Choosing the Right Roof for a Historic Home

November 17, 2020 by Infinite Roofing Leave a Comment

Owning a historic home can be challenging to restore and maintain but preserving its beauty is worth it. If you are lucky enough to own a home in a historic district then you know that there are certain guidelines that you must follow to be sure all the details are correct. The roof is arguably the most important feature in any home because it protects everything beneath it. The roof keeps the structure of a historic home and all its features safe from the outside elements and water intrusion.

Historical homeowners main concern when preserving its features is water intrusion, as this will damage the home in ways that oftentimes cannot be fixed. Most of these older homes are made from less durable materials than homes that are built today, this means that water intrusion has a much larger impact. When preserving the roof as it was in the past, you can usually keep the home in good condition that is time-period appropriate with hard work. If you diligently conduct routine roof inspections, and work with qualified local roofing contractors from the best roofing company, who have mastered historical techniques it is very possible to keep your historical home intact.

If you own a historic home chances are it is located in a historic district, and in these districts there are guidelines that must be followed. We at Infinite Roofing have replaced many roofs on historic homes located in historic districts within Saratoga Springs and we must adhere to their guidelines. These rules and regulations are to keep important character defining features of the building in or as close to the original as possible. The shape of a roof, materials used, and its details all contribute to the historic character of the home. As a roofing contractor it is our job to research specific guidelines that a city implements to properly conduct the job. Saratoga Springs has supplied historic district design guidelines so you clearly know how to preserve the building.

Oftentimes restoration experts decide to install a modern roof on a historic home, keeping all the details in place with the best interests of the property and budget. When working with the best roofing company they will agree that adding modern materials provides superior protection and much less maintenance costs, also adding a new roof will increase the homes value. Always check with the historical authority to make sure the materials you plan to use are approved, it is possible to use newer materials while still keeping the look of the past. Installing a more modern roof doesn’t ruin the architecture, in fact many newer materials can replicate older styles and details to match original materials.

The first thing you should do is start researching your type of historic home’s roof, this can take several months, especially when you need approval from a historic authority. If you are experiencing major leaks or other issues you might need to temporarily path up the roof yourself in order to protect the home. If you have your local roofing contractor patch an area of your roof, make sure they are careful about how to patch it. You don’t want them removing evidence you might need later on, such as an old layer of roof under the current one. In this case it’s best to not opt for a DIY patch, using a roofer with restoration experience is recommended.

Review Documents

If you have access to any documents pertaining to the house such as old pictures, journals, original blueprints, or newspaper clippings, review them for ideas on original materials and colors of the roof. This can be helpful to keep the integrity of the roof preserving details, an example of this would be if wooden shakes have been cut in unusual angles or shingles that were laid non-traditionally. It is important to take down any details to give to your local roofing contractor.

Look at the Physical Evidence

Try to keep all previous materials such as old wood pieces, nails, and scraps that may be helpful to tell which type of roofing system was used. Your local roofing contractor may be able to tell what kind of roof was used and also which materials can be swapped out for optimal preservation. Choosing a roofer with previous knowledge and experience with restorations is crucial to have the best chances of replicating the home’s previous roof.

Consulting with Historical Organizations

As stated previously if you own a historic home chances are that it is in a historic district, and within these districts there are rules and regulations that must be followed. You may have to face many restrictions about which changes you plan on implementing to your home’s roof. Some other restrictions include building codes but some areas will make expectations for historical homes. Even if you have to use traditional roofing materials that are available, oftentimes the use of modern underlayment can be used. This is because it better protects the roof from weather influences and is not visible or interfering with the outer appearance.

Types of Historic Roofs

Time	Style	Materials used
Pre-Revolution	Georgian or Federal	Wood Shingles
18th Century	Federal Style	Wood shingles or Slate
19th Century	Italianate, Greek, Gothic	Metal, Wood, Slate
20th Century	Bungalow, Craftsman	Asphalt shingles, Slate

Historic Roofing Materials

Material	Time Period	Details
Wood Shakes	All periods	Type of wood used was dependent on the area.
Clay tiles	Starting at the 17th Century	Primarily used where there was a Spanish influence.
Slate	18th Century	Seldomly used because of its price and difficulty to install.
Metal Roof	19th Century	There were several styles and materials used.
Shingles	20th Century	3 Tab asphalt shingles.

Wood Shakes/Shingles

This was the most common historical roofing material in the earliest days to the 19th century. The type of wood material used and techniques varied so if your home had wood shakes or shingles you will need to gather more information on how to replace it. Wood is the fastest roofing material to deteriorate so it must be treated in order for it to last.

Clay Tile

This type of roofing material was mostly used in the colonial period where there was Spanish influence. When clay started to be used in the Northeast the tiles were flat compared to traditionally rounded tiles, this was due to English and French influence. Replicating the shape and colors of old clay tiles can be very challenging, if your home has clay tiles you might need to explore other materials.

Slate

Slate began being quarried in America starting in 1785, it was rare to see on many homes but it was available. Once the railroad was developed slate spread and made it much easier to transport the heavy slabs. Because of its limited availability and significant weight, slate was not a popular choice when comparing it to wood shakes/shingles. Although it has many benefits clay tiles are a much cheaper alternative.

Metal

Metal was a popular roofing material but it was very expensive and at the time only lead and copper were suitable. This roofing material was more common on churches and government buildings rather than residential homes. In the 1870’s metal was cut from sheets and made into shingles, some had patterns and mainly used for gable roofs. Metal gained more popularity in the 1920’s also when asphalt became popular.

Asphalt Shingles

This roofing material was introduced in the 1900’s but did not become widespread until the 1920’s, the look resembled our 3-tab shingles today.

When restoring a historic home using substitute roofing materials has become more popular although some historical societies vote against it, others do agree protecting the home as a whole is more important. Modern materials provide a longer roof performance and keep the original structure intact. Seeking out alternative materials can also be very cost effective while keeping the same style of the original roof. Many more homeowners may choose to restore historical homes if the cost and hassle are reduced.

How To Inspect a Roof

November 10, 2020 by Infinite Roofing Leave a Comment

When it comes to doing maintenance around your home, the roof is easy to forget about. Doing a professional inspection once a year is recommended but you can easily inspect your roof on your own. Being aware of the condition of your roof will help you get the most out of it, by correcting any issues you see before more damage is done. The most common cause of water damage is from a leaky roof so it is important to be sure to properly inspect it at least once per year, and also after any major storms. We can easily help you identify things that may be problematic on your own, so you can then make a decision if a repair or full replacement is needed. Inspecting your roof has never been easier with these steps!

What happens during a roof inspection?

First step would be to walk around the exterior of your home, inspecting your roof from the ground to see what you can see at eye level. Inspecting your roof from the ground can still give you a good example of its condition if you don’t have a ladder or you’re afraid of heights. Look for signs of any damage, sagging, or ageing and take notes on what you think might be an issue to let your local roofing contractor know. While you are looking up at your roof, be sure to check out the flashing. Flashing is the main entry point for water and needs to be kept in good shape to work properly. Damaged flashing can cause immense damage under the surface of your roof. If you see damaged flashing a professional inspection may be necessary to be sure there are no underlying issues.

If your home has skylights examine the inside where the seams meet your ceiling and also on the exterior, where the shingles meet the skylight. If you see old shingles around your skylights you may have water damage. Looking closely at soil stacks, if your home has one. This is important to check for any cracks and issues with the “stack boot,” and not to opt for a cheap version that will not last you. Installing a soil stack that won’t last you as long as your roof will only cause you bigger problems down the road.

Inspecting your chimney is an area that you are able to check out without having to hop on top of your roof. Make sure to look around the perimeter of the chimney where water is directed away from your house, during heavy snow or rain, precipitation lands right at the chimney which can cause leaks or damage over time.

Look for moss, algae, or piles of leaves on your homes roof, these areas are notorious for costly leaks and water damage. Moss can severely damage the integrity of a roof because moss absorbs moisture and puts down roots causing degradation. These roots can lift shingles allowing constant moisture which can lead to mold and many other problems. Algae can adhere to the roof causing permanent stains and eventually damage underlying materials. If moisture seeps into the wood of your roof, it will cause rotting and compromise the strength of your roof.

As you are walking the perimeter of your home looking up at the roof, check to see if there are any curled or cracked shingles. Hot air from the attic often can cause shingles to curl away from the roof, putting you at risk for water damage and poor ventilation. Another important place to inspect is the attic, checking for rotted wood on the roof, and how well the insulation is holding up. If the insulation is poor there might be excess wear on the roof where heat can leak through. During cold winter months your homes heat leaking out can create serious issues causing ice dams to form. This happens when snow melts on the roof and runs down freezing along the way.

As you are looking at the condition of the shingles on your roof, also try to check for granule loss. Granules are the texture part of the shingles that feels slightly like sandpaper, these help deflect UV rays, make shingles fire resistant, and also makes packaging much easier. If you see loss of granules it may indicate your shingles have aged or been largely affected by severe weather. If you have a lot of granular loss then the shingles are no longer protecting your home from the elements, and you should consider calling your local roofing contractor for a professional inspection.

Another area commonly overlooked by homeowners is the gutters. Cleaning out your gutters is so important because that is why most water damage is caused by being clogged. A gutter system can accumulate up to 300 pounds of water and debris each year. The best time to clean out your gutters is in late spring, this is the prime opportunity to remove the buildup that accumulates from blooming and lingering winter. Along with maintenance for your gutters, pressure washing them out along with your roof at least once per year is suggested.

When should you inspect a roof?

Inspecting your roof should be a year routine maintenance, like we have said previously it is a great idea to get a professional roofing inspection once per year, usually in the spring, but you should inspect your roof and exterior of your home every few months. If you always have your eye out for potential problems it is much eraser to address the issues before they get too big and expensive.

You’ve completed inspecting your roof, now what?

After you have finished inspecting your roof with the help of these easy tips, review your findings. If you have found potential problems or concerns contact your local roofing contractor and make an appointment. Being proactive as a homeowner will save you a ton of money in the long run. As always when seeking out the best roofing company be sure to read reviews from their customers and look at pictures of their work.

Better roofing standards to protect against wildfires

October 27, 2020 by Infinite Roofing Leave a Comment

The year 2020 has been filled with terrible wildfires in the west, in areas that were not considered to be in the “danger zone,” such as Oregon, Washington and parts of California. Unfortunately these fires are still raging in many of these areas which resulted in destruction and evacuations. Many believe the top priority should be put on being better prepared and enforcing roofing materials to protect against wildfires.

California updated its residential fire code for building new construction in early 2008, requiring fire-resistant roofs, siding and other safeguards. This has protected 51% of the new construction homes built after 2008 that were in the path of wildfires. In contrast to the 12,100 homes built prior to 2008 with only 18% avoiding destruction. Many other states that are affected by wildfires have yet to consider adopting the same fire codes as California. The metal roofing alliance (MRA) is leading the trade organization to adopt the basic standard and create incentives to help homeowners protect their homes against wildfires in certain states and regions.

The most important factor to provide and protect against wildfires starts with how a home or building is constructed and designed. This all determines the behavior of wildland fires. Implementing mandates such as fire-resistant roofs, siding and other safeguards, help people and homes survive. Research supports that homes built after 2008 sustained far less damage than home prior. In areas such as the Gulf Coast that have been devastated by destructive hurricanes have had to learn hard lessons in the need to build homes that are more resilient to severe climates. Miami Dade is the first in Florida to certify hurricane resistant standards for structures which the Florida Building Code subsequently enacted across all requirements for Hurricane resistant buildings. It is important for the west coast to adopt a similar mindset for regional climate conditions for homeowners in wildfire prone areas.

Homes with fire-resistant materials vs Homes without

Your home’s roof is the most vulnerable part for ignition in the presence of a wildfire, certain materials like quality metal for a roofing system are essential. Metal roofs have a Class A rating for fire resistance and living in wildfire prone areas it can make or break you. Building materials that are fire resistant are not particularly expensive and when you factor in how long a metal roof will last you, it is definitely worth every penny. You should consult with your local roofing company to see what you can do to upgrade your home with fire-resistant materials.

Recent studies show that a new home built completely to wildfire resistant codes can be built for roughly the same cost as the typical home, and much less costly than potential fire damage. Fires are still raging on the West Coast so they are still being assessed, but the MRA urges builders and local officials to help better prepare homeowners for future wildfire seasons.

Mandate fire-resistant building materials

Similar to California, populations located in wildland areas have grown and continue to grow in recent years. These homes are located near flammable vegetation close to forested areas, raising a constant threat of wildfire destruction to land and homes. Newer standards that mandate fire-resistant roofing systems discourage potentially flammable materials like asphalt shingles and wooden shakes. It should be mandatory that every local roofing company in fire prone areas, educates their customers on fire-resistant materials, better roofing standards and strictly enforce the use of them.

Incentives to improve fire safety

Low interest loans, tax credits, local grants and other incentives are available in some areas to help people living in locations threatened by wildfires. Some owners of older homes that do not have the means to make fire-resistant upgrades on their own, so these incentives are a huge help. In 2009 California passed an ordinance declaring that a wood shake roofing system is a severe fire hazard. They then offered a cash incentive to replace their roof with a fire-resistant version and $4,500 to do so. Now because of this, the amount of wood shake roofs are very rare and no new home is built without a fire-resistant roofing system.

Providing education about fire safety

Communities that live in fire prone areas need to better educate their people on better roofing standards, the most resilient maintenance, home improvement, and preparation planning for fire season. There are many ways to help increase the odds that your family and home will be protected during a wildfire. There are various free resources from insurance companies that have a history in dealing with wildfires and in your local communities. “As we witness the horrible destruction wildfires have and are causing, the more we can do as an industry and community to help homeowners protect themselves against these increasing threats, the better,” said Ramey. “Investing in preventative measures now that help decrease risks is essential to guarding against costly devastation and suffering in the future.” (Ramey, MRA executive director)

Preparing your home for a wildfire

Even if you have purchased top of the line Class A fire-resistant roofing and home materials, sometimes nothing can prevent a wildfire from approaching your home. In these cases there are some tips to prepare your home and family for what could be coming. We suggest creating a home evacuation checklist to ensure you don’t forget anything, in the case that you and your family will need to evacuate your home. On this checklist we suggest having:

An evacuation bag ready to go ASAP
Make sure to know your communities emergency response plan to map out routes to drive
Shut all windows and doors of the house
Remove flammable curtains and window shades
Shut off your gas at the meter and be sure pilot lights are off
Leave your lights on in the house so firefighters can see your home in smoky areas
Shut off your air conditioning
Turn off your propane tanks outside and move BBQ away from the house
Connect garden hoses to outside valves and make sure water is on for firefighters to use
Do not leave water sprinkler on outside, it affects critical water pressure needed
If you have a ladder leave it against your home in the case that firefighters need to go on your roof quickly
Seal your attic vent with plywood
Clean up leaves and flammable debris
Continuously check your property and surrounding areas, do not wait for an official evacuation order, if you feel it’s time to go, the GO!
Check on your close neighbors and of course your pets

Why Does My Roof Look Wavy?

September 30, 2020 by Infinite Roofing 1 Comment

Although a wavy roof is unaesthetically pleasing, a common concern is if it affects the performance. It is agreed that a wavy roof takes away the appeal of a home, no matter the cost of materials that were used. Determining the underlying issues as to why your roof is wavy is the first step. There are a few possibilities for the reasonings behind a waved roof some more problematic than others. As always, contact a local roofing professional to determine a more thorough inspection of your roof to figure out the cause.

Installation

We can not say this enough “Not all work is created equal,” if you are looking for the cheapest roofing company, chances are you will get the cheapest work. Poor installation is a direct result of a wavy roof. It is urged to find the best roofing company in your area, who is trusted by customers who have left mostly positive reviews. Thankfully there are many platforms where a customer can leave a review for a company. Of course there will be a few disgruntled customers that no one can make happy, try and look at the overall rating of the company.

Materials

Depending on the type of roof you have, certain products or roofing materials are more prone to waving than others. For example asphalt shingles have the highest probability to wave and curl. Asphalt shingles are the lowest quality material and if not installed properly will cause your roof to resemble the ocean.

Foundation

Many people would not assume firstly that the issues they are having with their roof is because of their foundation because the roof is on top of their home, but this can be the case. The framing of your home has a huge impact on the way that your roof sits. The decking or “plywood,” is the foundation for your shingles, this can be an issue if it was not laid properly. Any issues with the decking on your home can result in a visible wave on the roof. Damaged decking can also be very dangerous, this could be an indication of water damage through shingles or issues with ventilation. If you think this might be the issue with your roof be sure to consult with a local roofing professional.

Underlayment

The roofs underlayment is a material that is placed between the roofs decking and the shingles. When asphalt shingles are being installed, felt paper is placed between them and the decking to act as a back up waterproof membrane. Felt is required as the first layer of roofing over the wood. If the felt paper is poorly placed beneath the shingles this will also result in a wavy roof. If the felt material was not fully dry pervious to installation or the day is extremely humid, chances are a slight wave can be seen. This type of roof wave is most commonly only seen after a new roof installation. Over time this issue is naturally corrected from the heat and is not a permanent issue.

Re-Roof

If you have a roofing company that suggests laying a new roof over your old one, we suggest you go with another company. This is a lazy way to install a new roof and will result in issues. If a new install is laid over an old roofing system, you will see an unnatural waviness that will never go away. Unfortunately your entire roof will need to be stripped down to the decking, if that is not damaged as well and reinstalled. Although you think you’ll be saving money by opting out of a the tear-off, it will likely cost you much more in the end if it was not done properly. Roofing warranties are another concern to think about, some warranties may not cover your roof if there is underlying damage unseen by the new roof laid over the top.

Shingle placement

The way shingles are laid out if they are not exceptionally precise, will result in a wavy roof. An inaccurate measurement or improperly sized shingle tab can be the culprit also. This is another reason that working with a trusted roofing company is essential. The lowest quote is usually not the best, you get what you pay for. If you want your roof done correctly, paying for experience is the key. Look for a roofing company that has been around for a decent amount of time, with reviews and pictures of their work to back up their claims on their website.

Sagging Roof

Roof lines should be as straight as an arrow, if you visibly see sagging, curling or dips then your roof has a problem. It is possible that it is caused by something basic that you could handle yourself, but it is more likely to require the intervention of a local roofing professional. As a homeowner you should become familiar with your home and roofs anatomy. If your home has an attic, climb up and take a look around, the horizontal boards under your feet are the roof joists or ceiling, the sloped board above your head are the rafters, this is all attached creating a triangle. This shape is meant to hold a large amount of weight, typically the weight of your roof and roofing materials.

A sagging roof can be the result of the ceiling rafters, the rafters are joined together in the center to create a longer span. With heavy snow, pressure is put on the roof and it can cause the rafters to push outward and turn. Together this causes sagging within your roof, even the slightest sag becomes noticeable from the outside. Problems should be evaluated by a local roofing professional so more damage is not done. The extent of the fix can be difficult to determine, unless you see visible broken rafters, beams, or joists.

Regardless of COVID-19, Solar panels still a great investment

September 16, 2020 by Infinite Roofing Leave a Comment

The global pandemic of COVID-19 has negatively impacted the renewable energy market but many suppliers are starting to recover after all these months. Although the virus has originated from China, they by far are the leading global producers of clean energy technologies which include solar panels. Since the pandemic began the demand for building materials has decreased, but interestingly the demand for solar is on the rise. Homeowners are seeing an increase in energy use since working from home or “sheltering in place,” this has led to an interest in solar energy to decrease energy bills.

Recent reports show a rise of 44% in solar system quotes from LG, the South Korean electronics giant, showing that people in quarantine are searching for solar power. Even more astonishing, a yearly increase of 50% has been reported as web traffic increases to solar power producers. The SEIA (Solar Energy Industries Association) has reported that the U.S. solar market will install around 100GWdc of solar between 2021-2025, this is a 42% increase over the last five years. 2020 may be full of unknowns, many factors point to rooftop solar being even more sought-out than ever before.

There is no other technology to generate electricity that is able to keep up with solar power, reduce costs, and improve performance. Over the past decade, solar panels have become more efficient and even cheaper to produce, this is giving natural gas and coal a run for its money. Solar power is out performing all other renewable energy sources in many ways. In 2010 the price per watt was around $2 fast forward to 2019, the price per watt dropped down to just around $.20. This 90% price reduction has helped push the global expansion of solar power on homes.

The efficiency of mono silicon based modules have replaced previous modules by increasing the watts to around 345, all for one-tenth of the cost from previous multi-silicon modules from 2010.

Over the last 12 years polysilicon production has more than quadrupled globally, while the average price of polysilicon has declined from $80 a kilogram in 2010, down to $8.40 a kilo reported in 2020. These numbers have created a momentum for the solar industry that will continue to grow well into the 2020’s.

BIPV or Building-Integrated Photovoltaics are dual purpose in that they serve as the outer layer of a building and also generate electricity. These systems provide savings on not only materials but on electricity costs as well, not to mention reducing pollution and adding architectural appeal to the building. BIPV can be used to replace the roof, façade, and other parts of a building. Larger commercial buildings favor the use of this technology because they have so much surface area exposed, giving them many options for solar.

With many color options and a steady decrease in material costs, BIPV is even more accessible to the average consumer. Many manufactures whom specialize in roofing have produced reasonably priced solar shingles to replace existing asphalt shingles. One famous company known for this is Tesla, they have innovated the solar shingle category and enhanced it with a 24/7 monitoring app. You are able to manage your solar system and energy consumption all from your phone, showing in real time each rise and fall of usage.

BIPV allows homeowners to reap the full potential of a solar powered roof without the draw backs of an unpleasant rack-mounted solar system on their roof. Many people have steered away from solar energy simply because it doesn’t look great on a home. As you can see what Tesla has done along with other companies, was to create a seamless beautiful roof without even knowing solar panels were there.

Another positive attribution to solar roofing systems, is that its increase in popularity has brought together roofing manufactures and solar installers. Previously each category was separate, now contractors are beginning to merge and train for both roofing and solar installation. This is great for the homeowner to be able to have solar installed with a highly knowledgeable roofing contractor, who knows the anatomy of a roof. You can look around and see if you have a local roofing & solar company for your installation.

Most states even cut tax breaks for homeowners that choose to have solar installed, in New York the federal tax credit gives a dollar-for-dollar reduction or a 30% credit. The value of the tax credit with decrease in 2021 to 26% and thereafter 22%. After the year 2021 the solar tax credit for residential homes ends.

Some states and local governments even offer cash rebates to homeowners who decide to purchase solar for their roofs. Usually these types of rebates or incentives are only available for a limited time so it’s best to take advantage if you see them in your area. In some cases these cash rebates can help reduce your solar system costs by 10-20%. Check with your local roofing & Solar company for more information.

Top 10 Benefits to an Asphalt Roof

September 8, 2020 by Infinite Roofing 1 Comment

In North America asphalt shingles are the top rated choice for a number of reasons that include, their versatility, weather resistance, and so much more. If you are thinking it may be time to replace your old roof, exploring the benefits to asphalt shingles is a good start. Remember your roof is the most important part of your home, it protects you and your family from all elements, so you want the best options available. Roofing materials are only as good as the roofing contractors laying them down, be sure to find the best roofing company in your area with positive reviews to ensure the job is done right the first time.

Versatility

The options are endless when you are looking for a certain color or shape of shingles. Asphalt shingles work with almost every type of roof no matter how large or complicated you think your roof is, these shingles will cover it seamlessly.

Variety & Design

Asphalt shingles come in a wide range of architectural shingle styles. Traditional 3 tab shingles work with many different home styles, dimensional and premium shingles are also available. Some architectural shingles are made to mimic the look of different roofing materials such as cedar shakes, wood or slate. Certain roofing materials like slate are beautiful but hard to work with and very expensive. The use of an architectural shingle that resembles natural slate gives you the advantage of your desired style but not the drawbacks that come with it.

For example, Owens Corning Berkshire shingles are laminated with a unique shadow line behind each tab to add dimension and mimic the look of slate. These shingles give a timeless and elegant look, resembling slate tabs and top of the line protection for your roof

Range of Colors

Not only does asphalt shingles come in a large variety of textures and patterns but many color options as well. If you are not only looking to replace your roof but give your curb appeal an upgrade, choosing a unique color will give it a boost. Up to 40% of your roof is visible from ground level so you should think of a shingle color that will blend harmoniously with its surroundings. Architectural shingle colors come in such a variety of colors, that you can be sure they will match your dream backyard and everything in it!

Affordability

Asphalt shingles are the most cost-effective roofing material and still offer high performance. Coming in at less than half the cost of wood and tile shingles, and significantly cheaper than slate and metal. The affordability of asphalt shingles goes well beyond the product and cost of installation.

Energy Efficiency

When your local roofing contractor installs your roofing system each component increases the energy efficiency of your home. Each layer including the roofs underlayment, decking, starter shingles, and outer shingles help your home to be energy efficient. Certain colors will reflect higher amounts of the suns UV rays which reduces the temperature on your roofs surface. In city areas the vast majority of roofs are covered in ‘Cool’ shingles, decreasing the overall temperature on hot days. This process will keep homes and buildings cooler so less energy is used to cool down the inside. Owens corning Cool Roof Collection are designed to reflect the suns energy and absorb less heat, without limiting style or color options.

Class A Fire Rating

Asphalt shingles can withstand a fire burning through a wooden structure for up to 2 hours, making them the most fire resistant roofing material.

Algae Resistance

You may not know this but algae is an issue in the roofing industry. Wood allows this type of growth on your roof that looks like black stains across the shingles, if this is a concern many companies offer shingles resistant to algae growth. Owens Corning created a stain guard plus shingle technology specially engineered to release copper over time to fight algae.

Installation Process

Out of all roofing materials asphalt shingles are the easiest to install. Each roofing contractor may not perform the same job but typically it is much easier to install asphalt shingles, compared to slate or metal. Be sure to do your research and find the best roofing company in your area to be sure the job is done properly.

Weight & Proportions

When you are thinking about replacing your roof there are certain aspects of your home you need to consider. If you have your heart set on a metal roof or slate roof you need to be sure that your home can structurally handle its weight. Fortunately shingles are not so heavy that this becomes a problem.

Ease of Repair

Although we don’t like to think about having to repair a new roof that you just had done, sometimes life happens and down the road you might need a repair. With certain roofing materials such as metal or tile, you might struggle to find a local roofing contractor capable to properly perform the repair. These roofing materials are more difficult to remove in order to get to the problem.

The Dangers of Asbestos

February 14, 2020 by Infinite Roofing 1 Comment

What is Asbestos? Why is it Dangerous?

Asbestos is a naturally occurring substance. In the environment, it poses virtually no threat to humans. However, the problem with asbestos initially arose out of the full-scale mining, extraction, and use of the substance in the roofing industry which led to an increase of the amount of asbestos in the air. Asbestos fibers are microscopic, so when they are exposed they can become airborne and inhaled. Once inhaled, they can lodge in the outer tissue of the lungs and abdomen, which over time leads to inflammation, scarring and the eventual formation of fatal diseases such as lung cancer. This is why many homeowners have begun to get asbestos roof removals done for their safety. Many homeowners today are seeking to get an asbestos roof removal once discovered.

How Can I Tell If It’s Asbestos?

The reliable way to know if your home contains asbestos is to hire an environmental consulting firm or asbestos building inspector for asbestos testing. They’ll take fingernail-sized samples and test them in a laboratory. You can’t see or smell asbestos, but exposure to loose fibers can cause lung diseases such as mesothelioma, asbestosis or lung cancer. The naturally occurring, flame-retardant mineral fibers are too small to identify without a microscope, so don’t believe anyone who claims you have asbestos but hasn’t done testing.

Is An Asbestos Roof Dangerous?

One of the widest uses of asbestos in the building industry was in roofing. Due to its heat and fire-resistant properties, asbestos was added to many roofing products including roofing tiles. Cement tiles were not comprised solely of cement. Cement roofing tiles were largely made from cement, with the now-banned product added into the cement mixture. Depending on the manufacturer, the cement tiles would typically be made with between 10 to 15 percent asbestos.

In addition to its heat and fire-resistant properties, asbestos has excellent strength and durability features. New homes built prior to the 1970s with asbestos roofs, were lauded for the longevity of their roof systems, as the roofs had a life expectancy of 30 to 50 years. Although asbestos serves as a formidable roofing material, it exposed people to a list of compromising health issues, which led to its eventual ban.

Do I Have to Remove My Asbestos Roof or Siding?

Many homes, especially the ones that were built at the turn of the twentieth century, have siding or roof shingles that contain asbestos. Asbestos has plenty of quality features, including its durability and fire-resistance. However, it also poses many significant health hazards. The inherent question that comes with this is whether it is necessary to remove your asbestos-containing roofing shingles or fiber cement siding to protect your family’s health?

We know that there are many homeowners who want a roofing company that does asbestos roof removal. A homeowner should be aware of the harmful effects that occur with asbestos when someone breathes in a tiny, sharp fiber, which irritates and inflames the lungs. If the asbestos is not airborne, it is not a danger. The asbestos in shingles, siding, and other home products is encapsulated, which is surrounded by a coating of something else that keeps it from becoming airborne. If your roof or siding shingles are in good condition, they are unlikely to pose a health hazard to you or your family. The U.S. Environmental Protection Agency recommends not disturbing asbestos if at all possible.

Unfortunately, while asbestos home products are durable and long-lasting, everything must be replaced eventually. In 1989 asbestos was banned, leading to the asbestos roofs and sidings to fall into disrepair. Many asbestos roofs and sidings are damaged, cracked, or broken. Asbestos siding in particular, however, has a tendency to chip, crack, and break with normal wear-and-tear of family life. This can release the fibers into the air, which poses a threat to your family’s and neighbors’ health.

How Can You Tell If Old Siding Has Asbestos?

Many manufacturers made their products to look like asbestos-free products, so it is not really possible to determine if your siding contains asbestos just by looks. You can easily send a sample to a lab if you suspect that it may contain asbestos. Or you can hire a specialist to take a look at the siding so that they can determine if you have an asbestos siding.

Can I Install New Siding Over Old Asbestos?

Some people try to attempt to solve the problem of deteriorating asbestos siding by installing vinyl siding over on top of it. This practice is not recommended for a number of reasons. First, the siding installation process itself, nailing into existing boards or tiles, is enough to disturb the existing material and create a dangerous condition. Second, installing vinyl siding over any existing materials, particularly those in poor condition, can lead to additional problems in your home and can hide the development of those problems until they become extremely large and costly to repair. Therefore, hiring a specialist or roofing contractor who has the right education for asbestos would help in asbestos roof removal.

Can You Pressure Wash Asbestos Siding?

Painting asbestos siding is not difficult at all, as one of its benefits is that paint easily adheres to it and it is very durable and can last for decades without chipping or cracking. However, when cleaning the siding before painting, the important thing to note is that you should avoid power washing asbestos siding as it can chip or damage the siding and release the dangerous asbestos fibers into the air. If you do pressure wash, use a gentle touch if possible and stop immediately if you find that you’re knocking pieces of siding off. This means that you’ll have to take some extra time cleaning and prepping the siding before painting and rely on a garden hose and sponges instead. If you manage to chip damage your siding and worry it may be made with asbestos, make an appointment to have the material tested to confirm.

Do You Have to Disclose Asbestos When Selling a House?

For starters, it is not illegal to sell a house with asbestos. Obviously, buyers would much rather buy a home with no asbestos concerns. However, outside of a thorough inspection, there is no way to tell if a home contains this potentially toxic material. If you know your house has asbestos, you might disclose the information to buyers. Again, it’s not illegal to sell a home with asbestos, but you can be liable for not disclosing the information to the buyer if you knew it was present beforehand.

Cement Asbestos Roofing

When asbestos came into the picture many manufacturers experimented with it. In the 1880s manufacturers used asbestos fibers in mixtures that resulted in building products like insulation for steam pipes and boilers. It was eventually being mixed in Portland cement and the paste was used as a roof repair compound. In 1907, process equipment was invented that produced rigid sheets from the cement-asbestos mixture. These sheets could be pigmented and cut into manageable shapes and were able to have textured patterns pressed into the surface. The result was very durable siding and roofing shingles that imitate traditional, natural products, both less expensive and lighter than slate. They don’t rot or warp like wood and are extremely fire resistant. It’s not at all surprising that the popularity of these asbestos sheets skyrocketed throughout two-thirds of the twentieth century.

The manufacturers of individual asphalt shingles, which were less expensive and more flexible than cement asbestos, were major competitors for market share in the roofing material industry by the 1920s. In the late 1930s, asphalt strip shingles, coated with granules in a wide variety of colors, were the most popular roof covering.

Asbestos-containing products, like the cement mixture, posed very little health risk if the material is kept in good condition and not disturbed. Severely worn or damaged asbestos roofs and walls, or improper repairs, alterations, or removals can allow the release of the fibers and risk the health of the occupants and neighbors. The EPA provides detailed information about managing asbestos-containing products on its web site.

The Problems

Cement asbestos roof shingles typically have a much shorter life than the siding panels. If a replacement is needed, removal can be a significant expense. If the shingles are severely weathered, to a point that the material can be crushed by hand, professional abatement is needed. Precautions should still be taken even if they’re intact. The fasteners securing them should be kept wet and lowered to the ground instead of being tossed down. Individual states and municipalities may also have additional requirements for the removal and specific requirements for disposal.

Like tile and slate roofs, occasionally there may be some cracked, broken, or missing tiles or slates, or flashing repairs that may be needed. Maintaining an asbestos tile roof can be difficult. Finding contractors willing to work with the material associated with the A word can be a challenge. It can also be a challenge to find contractors that are mindful of the brittle nature of these tiles. Some roofing contractors, experienced with slate and tile roof repairs are willing to repair and restore asbestos tile roofs. The tools, equipment, and techniques they use for their regular repairs are well-suited for working with the brittle shingles. There are also a few good sources of salvaged replacement shingles that with luck can be a close match to the existing roof.

Hopefully, the remaining cement asbestos roof tiles are in good to repairable condition and will be properly maintained for the maximum potential life. Those that are beyond safe repair will need to be properly and professionally removed, and will likely be replaced with a roof that looks like most other roofs, and will likely only last one-third as long.

Polyurethane Foam vs Duro Last

January 31, 2020 by Infinite Roofing Leave a Comment

Spray Polyurethane Foam and Duro Last go head to head in the market, the reason being that they both have the same benefits for your commercial roof. However, some may say that Polyurethane Foam is better than Duro Last and some may say the opposite. Well, we are going to compare them both and see exactly product is more beneficial for your roof.

What is Spray Polyurethane Foam?

When talking about Polyurethane Foam, the question you might ask is, what is the sole purpose of Polyurethane and how can my commercial roof benefit from it? What are the benefits of installing the spray polyurethane foam roofing system and how would it outweigh the advantages of other roofing systems? Many manufactures use SPF simply because of the ease of installation, the impressive performance, affordability, and durability. Property owners love the idea of it because of the protection it provides for their roof. Some of the benefits that SPF provides are energy efficiency, durability, a seamless surface and it’s environmentally friendly. Sprayed Polyurethane Foam has been used as a commercial roofing and insulation material for over 20 years.

Energy Efficient Insulation

Spray Polyurethane Foam provides the highest level of insulation against air and moisture, it also provides that perfect thermal barrier. Therefore, spray polyurethane foam carries out as an air sealant, where it closes the spaces that would allow the air to escape and add dollars to monthly energy bills. Based on the Environmental Protection Agency’s Energy Star program they estimated that when adding insulation and sealing air leaks, you can save about 20 percent on your monthly bill. Among other roofing and wall insulation, it has the highest R-value per inch. When a system has a higher R-value that simply just means that there is greater insulating power.

Durability

When applying a Spray Polyurethane Foam roofing system it is able to improve a building’s strength and effective lifespan. When SPF is sprayed on to the surface it conforms and adheres to the material, which creates a strong bond to protect the roof. That layer of spray foam is seamless, which can eliminate the ability of water to seep through weak spots. Therefore, if there was to be a flood on your commercial roof where spray polyurethane foam was sprayed, it would be highly resistant to water damage. When spraying the foam in the cavities of the walls it increases the durability of the wall system because of the foam’s ability to conform and adhere to the surface and create a strong bond where it’s sprayed. One of the best qualities that spray foam has, is that it is able to expand and contract with the changing temperature. Roofing contractors would be able to install the SPF in any climate or harsh environment and it will not be at the mercy of the conditions. Thus, guaranteeing a strong and legitimate bond.

Seamless Surface

The way that roofing companies apply SPF is by a liquid through a high-pressure spray gun. When the liquid lands on a surface it ends up expanding, covering the entire roof over a large area. Doing this provides a seamless membrane that fills in the cracks, holes, corners, and crevices along the base of the roof. Because spray foam roofs have no seams, there is a less chance for water to leak through. Spray foam is a solid, seamless barrier that is able to protect your roof from moisture and air.

Environmentally Friendly

Spray Polyurethane Foam is an environmentally friendly alternative to fiber insulation, such as fiberglass or cellulose. Spray foam insulation reduces the impact on the environment by using renewable resources and recycled plastic waste in their foams. Therefore, with the proper maintenance, your roofing contractor would be able to recycle the membrane of your roof whenever the time comes to replace your roof, and recycled materials would be used to create a spray foam. Also, keep in mind that Spray Polyurethane Foam insulation can improve the air quality by creating an impermeable air barrier against pollen, pollutants, and dust. With this, it makes it perfect for people who suffer from allergies, asthma or chemical sensitivity.

The Downside to SPF

We know that there are some great benefits to Spray Polyurethane Foam. However, here’s the downside, some people have poor thoughts on the spray foam because some commercial roofs were installed incorrectly using the foam insulation. This is one of the biggest reasons that there are negative reactions to the spray foam. To get the most benefits out of the Spray Polyurethane Foam roofing system, then your roofing contractor must install it correctly. Hiring a professional, certified roofing contractor would be able to provide your commercial roof with a special product that supply the savings in energy cost that SPF provides and they will reapply the SPF every ten years to ensure its quality. However, many believe that over time, these benefits will slowly disappear in comparison to the Duro Last roofing system. When compared to Duro Last, Duro Last uses a white or grey membrane that reflects the UV rays from the sun without having something additional applied to it.

What is Duro Last?

What makes Duro Last equivalent to SPF? What benefits from Duro Last could potentially outweigh SPF? For starters, Duro Last roofing systems contain the highest quality materials and undergo demanding quality control checks during the manufacturing process. A Duro Last roofing system is a reinforced thermoplastic (PVC) single-ply membrane that would be a perfect fit for your commercial roof or industrial building that has a flat or low slope roof. It is said that the Duro Last roofing system can last longer than the spray polyurethane foam. There are elastomeric coatings for roofs that can be applied and reapplied that can help make the spray foam last longer. When the PVC membrane is used and the ISO insulation is installed underneath the membrane, then Duro Last can last longer than the SPF. The only way that the spray foam can last longer than 20 years is if it is maintained and reapplied correctly. It would have to be recoated every ten years or so and would require a strict maintenance program in order to maintain all of its benefits. Duro Last offers a 15 and 20-year warranty on their products which many building owners prefer.

Prefabrication

With Duro Last, each roof is measured and manufactured to the exact size of the roof, accommodating for every rooftop penetration. When the Duro Last roof is prefabricated in the factory, it eliminates just about up to 80 percent of seaming that would’ve been done on-site during rooftop installation. Which in return improves the long-term performance of the roofing system. It is actually the only roof manufacturing company to offer prefabrication of the entire roofing system. Doing this provides an excellent fit and delivers leak-proof protection. A custom- fabricated Duro Last commercial roofing system is long-lasting and is one of the leaders in roof leak prevention.

Durability

Comparing Duro Last to SPF, the durability is quite similar in the sense that the Duro Last roofing system is resistant to any water damage. Duro Last has a custom flashing that is able to resist any ponding water, or collecting of water, which is very common in a commercial roof. Once the roof is installed, it is virtually maintenance-free, unlike other roofing materials that may require regular maintenance or other repairs. Not only is it resistant to ponding water, but it is also resistant to fire, chemicals, grease, high winds, and punctures. Just like the spray foam, Duro Last can easily accommodate for a wide range of temperatures.

Energy Efficient

The Duro Last roofing system has a white membrane that has the highest reflectivity retention of any single-ply membrane. Which means that you are able to save more money on cooling costs, very similar to Polyurethane Foam. Out of the white, single-ply products rated by the Energy Star program, Duro Last is the only roofing system that has a reflectivity retention of greater than 85 percent after three years of weathering. The sustained reflectivity rate is saving a lot of energy and money for building owners. The Duro Last roofing system is mechanically-attached, and insulation can be placed under the membrane during the installation of the roof, which would reduce the amount of heat loss in the winter.

SPF vs Duro Last: Which is Better?

Spray Polyurethane Foam is more costly than Duro Last because of the installation process. It is as easy as needing a piece of special equipment in order to install the spray foam, even to reapply it, but the special equipment is expensive to use. However, Duro Last is easy and quick to install as well without the required expense of high tech equipment to be used. Many know spray polyurethane foam is sprayed to secure the roof. Duro Last is installed with screws and plates which gives it that air and watertight fit. Duro Last can also be applied over EPDM rubber roofs, TPO single-ply, and metal roofs. It’s also affordable, plus it carries a longer lifespan and more benefits than polyurethane foam does. However, we are going to go against Duro Last a little. The reason being, that polyurethane foam can be applied to surfaces with irregular shapes and penetrations. Another benefit of SPF is that it can be applied over an existing roof, which eliminates the need for the cost of tearing off of an old roof. Sprayed Polyurethane Foam roofing systems are also much lighter than Duro Last. When placing the insulation on the outside, the foam insulation reduces building movement and thermal shock. Spray Polyurethane Foam is one of the best insulators that a building owner can buy. Closed-cell SPF is the only insulating material that does not soak up water. Since SPF is applied to the roof surface, it is recommended for your commercial roof that your qualified roofing contractor assures the material’s integrity.

So is SPF better than Duro Last? Or is it the other way around? The decision comes down to the requirements of your project, your budget, and personal preference. Both roofing systems are high quality products that will ensure the quality and protection of your roof. It is important to sit down with your commercial roofing contractor and discuss the pros and cons of each of these methods to come to the best solution for your commercial roof.

The Importance of Roof Flashing

January 7, 2020 by Infinite Roofing Leave a Comment

What is Roof Flashing?

Roof flashing provides protection for different areas of your roof and works in conjunction with your roofing material. Flashing is applied to roofing corners and valleys, as well as objects that jut out through your roof. So let’s talk about what exactly is roof flashing. How does it work? Where is it used? And the different roof flashing types such as counter flashing or step flashing.

Flashing is usually built out of metal, but it may contain steel, zinc, copper, aluminum, and even plastic or rubber. Flashing is used to keep roof components waterproof and prevent any damage. Without flashing, roof components such as the junctions between walls, dormers, or chimneys may come into contact with water which can saturate, leak, and damage the component or the structure of the house. In short, the roof flashing keeps the integrity of your home intact.

The way that flashing works is by connecting to various roofing components, and it can be overlapped and connected with one another in order to keep leaks from penetrating the roof or any of the structures on your roof. Flashing can be installed with nails, glue, and caulking in order to keep your roof waterproof.

Roof flashing installation occurs throughout your roof, including all of the following places:

Valleys and Joints – the joints found throughout your roof structure are more susceptible to penetration from water, as are roof valleys. Roof joints often aren’t watertight, and roof valleys collect more water than the rest of the roof. The roof flashing ensures that these critical areas of your roof are protected.

Roof Protrusions – If there’s anything jutting out of your roof, there should be flashing to protect it. If, for instance, you have cables that tie into a satellite that’s installed on your roof, flashing can protect the opening for the satellite cables free from water and prevent any future damage.

Drip Edging – Drip edging is flashing that is applied to the edges of roofs where there aren’t gutters. Think of drip edging as a specialized roof flashing at the edge of your roof that acts as guides to prevent water from getting behind gutters and ensure that all water is directed away from your roof.

Chimneys – Chimney flashing is necessary since water can run through and collect right at the base of a chimney. Chimney flashing should be installed at the base of your chimney to keep water from infiltrating the joint between your roof and your chimney.

Pipes – It’s likely that your roof has a few pipes that penetrate the surface of your home. For instance, you probably have drain-waste vents which keeps the pressure from building up in your plumbing. These pipes can compromise a waterproof roof if they are left unprotected. Specialized “pipe boots”, which work exactly as it sounds, can be placed around these pipes in order to protect your roof.

Kickouts – Kickout flashing is installed at the lowermost joint between your roof and your wall. The kickout flashing, also known as diverter flashing, diverts rainwater away from your wall and into your gutter to avoid any kind of saturation leaks in your roof.

If you have ever noticed that there are any leaks coming from around your chimney or vent, most likely your flashing was not installed correctly or is no longer sufficient. The main purpose of roof flashing is to protect your home from moisture & saturation. The flashing extends below your roofing and adjacent to siding to create a solid, weatherproofing seal on your home to protect you from the elements. It is also much more durable and lasts longer than trying to seal or caulk around the spaces. Before sheet products were available, builders had to use different methods to try to minimize water penetrations. These methods included angling roof shingles away from the joints, installing chimneys at the ridge, and building steps off to the sides of chimneys to divert water.

Furthermore, roof flashing is less susceptible to temperature variations. If and when the other components of your roof shift slightly, due to expansion from heat or ice, the flashing will still be able to act as a barrier from the elements. If you have any concerns or thoughts that you could be having leaks call your local roofing contractor.

Flashing also adds a clean, finished look to your roof. There are areas of roofs and exterior walls that are more susceptible to leaks and water damage such as the valleys or junctions where roof sections or walls meet. It is usually installed around structures that intersect with the roofline such as dormers, skylights, vents, and chimneys. Flashing comes in a variety of materials to accommodate the desired look for the consumer. Although you may see rubber or plastic flashing out in the market, metal flashing is the more prominent kind of flashing. One of the most common types of metal flashing material used is aluminum because it is usually the most cost-effective, durable, and weather-resistant.

Counter Flashing

For starters, counter flashing is only one type of flashing and is a technique that is used to help prevent moisture from penetrating into a home behind the vertical flange of a headwall or sidewall flashing. Pieces of metal are installed in order to prevent water from passing through a structure at its joint and ensure the water is directed away from the structure. Sometimes the material used, such as vinyl, for the exterior wall siding will be enough to serve as counter flashing itself and other times a separate element is installed. This is especially important in a structure where walls are either brick or stone. The counter flashing installation process is one of the most important parts of completing any roofing system. This type of flashing should be used in conjunction with base and step flashing, to help form a waterproof barrier.

The waterproof membrane is the first layer that is laid down before the shingles are installed, called the base flashing. This membrane not only covers the first layer of the roof but also gets turned up the nearby walls or chimneys to help with the flashing process of any joints or valleys between structures. Next, L-shaped pieces of metal, typically aluminum, are placed under each shingle that is installed next to a vertical wall. One side of the L-shaped aluminum flashing lays underneath the shingle while the other side attaches up against the side of the wall. This layer is called the step flashing.

In contrast to step flashing, the next layer is installed as a continuous strip. It is installed either behind or on top of the wall adjacent to the shingles and covers the step flashing. This final layer is called counter, cover or cap flashing and most commonly consists of aluminum or galvanized steel, but is also seen made with copper, tin or even plastic. Depending on the situation, a roof with step flashing installed could sufficient in itself when combined with vinyl siding that can double as counter flashing as long as the step flashing goes underneath it. Otherwise, counter flashing is a critical requirement for all roofs.

Counter Flashing Installation Methods

Counter flashing installation can be done using one of three techniques. The first is through-wall counter flashing, which secures the flashing material to the wall cavity and the exterior siding or masonry covers it. This type of installation is only plausible during a new construction project; otherwise, it typically proves to be cost-prohibitive.

The second technique used to install counter flashing is called surface-mount flashing. This technique attaches the flashing to the exterior siding by using a sealant, typically caulk, to seal the top of the surface-mount flashing. It’s the least expensive method of installation, however, the caulk seal will need to be monitored and eventually repaired or replaced over time because it will inevitably break down.

Reglet flashing is the compromise between through-wall and surface-mount flashing. A cut is made into the exterior masonry at a 90-degree angle and the flashing material is secured in the groove made by the 90-degree cut and bent down to run parallel the exterior masonry. Although it is a more expensive and invasive technique than the surface-mount flashing, reglet flashing does not need maintenance and will last much longer than a sealant. Because of this, reglet flashing is a more convenient, long-lasting option and is recommended over the surface-mounted flashing.

Counter Flashing at Brick Headwalls and Sidewalls

Installing headwall and sidewall flashing correctly becomes more time consuming when the exterior wall covering is brick or stone.“Time-consuming” can mean “more expensive”, which is why a lot of the counter flashing you’ll see at brick and stone walls will be incorrectly installed and will solely rely on some sort of sealant to prevent moisture intrusion. Sealant eventually dries, shrinks and cracks, leaving room for moisture intrusion and future water damage. This is why it is recommended to install regret flashing to ensure the most protection from moisture intrusion.

Step Flashing

Step flashing is an L-shaped piece of metal, typically aluminum or galvanized steel, and is used where a sloped roof intersects a vertical wall. Step flashing is interwoven with the shingles and act essentially as shingles with an unturned leg to allow a transition of the vertical drainage plane of the wall to the drainage plane of the roof. One side of the L-shaped step flashing is behind the vertical drainage plane or sealed to it with some sort of sealant and/or sheathing tape. The bottom leg of the step flashing is placed over the roof drainage plane. A critical component of the step flashing is the piece that is at the end of the slope of the roof is called the kickout flashing. This roof flashing directs water away from the adjoining wall and ensures that the step flashing is not collecting water on the surface of that wall.

Is Continuous Flashing Better Than Step Flashing?

Continuous flashing is sometimes seen where a roof meets a sidewall instead of step flashing, but in the long run, step flashing will do a better job of preventing water leaks.

Step flashing redirects the water back onto the shingle and away from valleys and joints. Even if one piece of step flashing fails, the next flashing and shingle below it start the process over again, providing a system to protect your roof from water damage. Continuous flashing against a sidewall is one way to install flashing on a roof, but it’s not the correct way. Some may think that a single piece of flashing would offer more protection than many pieces of step flashing, but it doesn’t work that way. Once even a small section of the continuous flashing fails, you’ll have a leak. Each additional rainstorm will add more water, and before you know it, you’ve got rotted wood and a roof inspector in your home.

Step flashing offers far better protection from leaks because even if a single piece of step flashing fails, the water just hits the next step of the flashing. The flashing then directs the water onto the shingle and the water drains down the roof.

Kickout Flashing

Kickout flashing which can also be called diverter flashing is a special type of flashing installed at the edge of the flashing that diverts rainwater away from the cladding and into the gutter. When your roofing contractor installs kickout flashing properly, the flashing will provide excellent protection against the penetration of water behind the exterior wall covering where the flashing ends. Kickout flashing is required regardless of the roofing material excluding brick or concrete block.

Yes, there can be several factors that can lead to rainwater intrusion, but a missing kickout flashing, in particular, often results in concentrated areas of water accumulation and potentially severe damage to exterior walls. If you happen to find saturation and possibly plant growth on the exterior siding of your home, you may have missing kickout flashing causing the water damage.

Apron Flashing

Apron flashing is the metal that covers the transition between a roof slope and a roof penetration such as a dormer or chimney. Having this flashing properly installed is crucial in protecting some of the most vulnerable areas of your roofing system.

Apron flashing is usually applied as part of the two-piece roofing system. The apron is the lower L shaped piece that replaces the normal step flashing, which covers the roofing material and extends up the vertical surface of the roof penetration. The second part of the system is something we’ve touched one, which is the counter flashing that extends parallel from the vertical surface and covers the vertical leg of the apron flashing.

The Importance

Now that you have had a breakdown of the important role that roof flashing plays when it comes to the protection of your roof, it is easy to see why it is needed on almost all roofing projects. Without roof flashing, our roofs would be much more susceptible to water damage, costing homeowners thousands of dollars in repair or replacement. So when having your next roof inspected or installed, be sure that your flashing is properly installed by your local roofing contractor to ensure the best protection for your roof.

Commercial Roof Maintenance

November 1, 2019 by Infinite Roofing Leave a Comment

Many people might ask themselves why they should maintain or how they should maintain their commercial roof. Well, preventing any problems that would require an emergency roof repair or replacement would be the best way to take care of your commercial roof. Taking care of your roof before the winter comes means that it will be in the best condition for the rest of the year. When your roof gets the proper maintenance, it helps it fair better during storms and extreme weather, which means there would be less of a chance of getting any leaks or other elemental damage. When something serious goes wrong with a commercial roof, such as severe weather damage, unforeseen circumstances, or lack of routine maintenance and routine inspections, this can cause an entire section of a building to be shut down. This is terrible for any commercial operation! Especially one that has business going on constantly. Therefore, any business, especially one that has a large amount of square footage dedicated to a roofing system, should have their roof maintained properly. Maintaining every part of your commercial roof is a key duty of the facility manager. Regular roof maintenance is essential to ensure the total integrity of the building, however, knowing how to approach it is a big responsibility.

Roof Warning Signs

A properly designed roof provides structural support, fire resistance and more. A minor issue like a tear in the outer layer or warped asphalt, sealant could pose a risk. Therefore, when hiring an experienced professional roofer they should do a routine inspection. During a routine inspection, they could look for some of the following warning signs.

Having bubbles or blisters on your commercial roof is a definite warning sign that should be taken care of as soon as it’s spotted. An improper roof application is typically a leading cause of roof blisters and bubbling. Bubbles appear on your roof when there is moisture that is trapped under the roofing materials, where the water evaporates, and the result is usually the formation of bubbles or blisters.

Your roof shouldn’t be uneven, simply for the fact that a roof is built to bear its own weight. If you happen to notice any part of your roof sagging, then contacting a commercial roofing contractor is your best bet so that they can look at your roof and determine what actions should be taken. A sagging roof could be caused by many different issues, among them, being accumulated moisture, additional weight on the roof due to the installation of new roofing materials on top of old ones for a long time and other factors.

Excess standing water also known as ponding is very dangerous for your roof. Standing water is defined as water on a roof that hasn’t been drained or evaporated within the 48 hour period after rainfall, flooding or any other causes. If it hasn’t evaporated within that period, you can be expecting it to remain for an extended period of time. The accumulation of standing water on a roof over time can lead to dangerous defects which would include leaks that may eventually allow hazardous mold to grow on your roof surface. When the standing water has been on your roof for a while it can begin to cause sagging, thus creating a larger dip/pool to hold yet more standing water. Once you get standing water, it often creates a vicious cycle that ends with roof repairs or even full replacements to counter the damage caused.

Regular Routine Inspections

Many commercial roofing companies recommend that facility managers, or their local roofing contractors perform a routine inspection of a roof twice per year, usually once in the spring and again in the fall. This will allow you time to address any concerns before bad weather could cause an issue or make any issues worse. It could be tempting to do the roof work yourself and you might even be lured into thinking that any roofing contractor is qualified for the job. However, hiring the wrong commercial roofing company will lead to more expense and wasted time correcting any issues they have caused. When hiring just any roofing contractor, they could be using inadequate materials or they could get injured while servicing your property. This can cause invalid warranties and cause your insurance costs to skyrocket.

An experienced commercial roofing contractor would be able to find any signs of a leak or any other type of damage. They would be able to pinpoint any loose materials that need to be replaced, overhanging branches that would need to be trimmed, along with any dirt and debris that would need to be cleared off. Hiring a professional commercial roofer, they would be able to visually survey the total roof system and check all the flashings, fittings and other roof-related accessories. Any blockage to drains or downspouts should be checked in order to prevent adequate water drainage. A routine commercial roof inspection would look for gaps or tears in penetration and flashings, proper seals on all rooftop vents and equipment, and any other signs of damage.

A proper commercial roof inspection would cover counter flashing as well. The purpose of counter flashing is to prevent moisture from entering behind the vertical flange of the headwall or sidewall flashing. Usually, the material covering the exterior wall serves as the counter flashing and often a separate slip metal flashing would be installed under the counter. Counter flashing is important mainly when it comes to brick walls. When properly installed, counter flashing sections are inserted into the mortar joints. Afterwards the joints would be sealed with an appropriate sealant. Counter flashing is also inserted into a groove cut into the brick, and then it is sealed.

During your routine inspection, your local commercial roofing contractor would conduct an interior and exterior exam. When conducting the interior inspection of the roof, you would be looking for discolored or water-stained ceiling and walls, raised or deteriorated areas on the wall, discoloration or water staining around window frames. There could also be rust or other deterioration of the roof decking, joists or other structural components, as well as mold on any interior surfaces.

With the exterior of the building, on the other hand, there could be excessive standing water on the roof’s surface that would most likely be caused by structural failing, broken purlins, broken joists, loose/buckled flashing or damage to the roof membrane. There could also be materials stored on the rooftop that should be stored elsewhere. You would also have to look for nails or screws in the roof deck backing out of the roof membrane, debris on the roof or in the drains and gutters, missing domes on drains and defective, damaged or missing masonry joints.

Maintenance Program

The most trusted providers of commercial roofing or re-roofing services often offer a commercial roof maintenance program that has a comprehensive plan. Proper maintenance can extend the roof’s life and reduce potential damage to the building’s interior, protecting one of a company’s biggest assets, their building. When setting up a commercial roof maintenance program, the recommendation is that once every two years you have a plumber check all the roof drain lines. For a comprehensive commercial roof maintenance program, you should create standardized documentation for each building that is being inspected to help maintain proper records. With that documentation, there should be a file for each roof, including the roof’s installation dates, records of repairs and updates, a map of any current leaks and every time roof maintenance is performed.

Proactive Vs. Reactive Roofing Maintenance

In order to know if proactive or reactive roofing maintenance is something that you want to go with, you should know what exactly they are. Proactive is to take control of the situation by actively preventing something from happening rather than responding to it after it has happened (reactive). On your roof, being able to spot minor problems before it becomes a bigger issue with a larger price tag, taking an active role in the maintenance of your roof by performing routine inspections and keeping up with minor repairs.

Reactive maintenance always happens after the fact. This simply means that the maintenance work and repairs aren’t addressed until there is very obvious evidence that a problem is present, such as missing shingles or water leaking into the home. Unfortunately, with reactive maintenance, warning signs of potential problems are often missed. The result is that damage and repairs often end up being more extensive and costly than they otherwise would have been. Many owners take an “out of sight out of mind approach” with their roofs. However, taking a proactive maintenance approach over the reactive maintenance approach not only extends the life of your roof but provides significant cost benefits.

Facility managers who choose to react to problems as they occur would generally pay an average of 25 cents per square foot annually for maintenance. On the other hand, facility managers who get their roofs inspected and repaired routinely before problems happen will spend less than 25 cents annually. Proactively maintained roofs last an average of 20+ years compared to an average lifespan of 13 years for reactive maintenance. The longer you can extend your roof’s life before replacement, the greater your total savings will be and the chances of a roofing disaster occurring on your property will decrease.
