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.

What Could Go Wrong With Hiring the Wrong Contractor?

January 24, 2020 by Infinite Roofing Leave a Comment

The most expensive component of your home is your roof. If you’re thinking about getting a full roof replacement or even a repair job, the local roofing contractor that you consider hiring is not something that should be taken lightly. When you hire a good roofing contractor they will use top-quality roofing materials, the right roofing tools and equipment, and will provide professional installation techniques to ensure that the final result will add value to your home. However, some homeowner’s do, unfortunately, make the mistake of hiring the wrong contractor. The majority of homeowners have a horror story about a horrible contractor and their experience with them. Unfortunately, there’s no shortage of unqualified, unlicensed, or even scam artist roofers advertising their services. Hiring the wrong contractor can cause significant damage to your home and will cost a great deal of money to get it redone.

What’s the real risk of bad contractors?

Hiring a good contractor is very important when you’re looking for the best quality for your home. A roof is what truly makes a place a home and a shelter from the elements. One of the most important indicators of a good roofing contractor is that they have the right credentials, for instance, valid insurance. A bad contractor won’t be able to provide you with valid insurance which most likely puts you, the homeowner, in a predicament. Let’s say that there was accidental damage to your home or someone got injured during the job, the matter can become ugly without having any insurance.

Another issue that should be considered is the warranties provided on both the labor and the materials used. If you are only covered for one and not the other, if something is amiss you will end up paying out of pocket for work and materials you already paid for. One of the biggest issues with hiring the wrong roofing contractor is that it can result in a financial disaster. Even though you may pay more for a quality roofing contractor and quality home repair work, it’s worth every penny in the end. A great deal isn’t always a great deal in the long run.

Using a roofing contractor without a license

Knowing that getting a roof done can be extremely expensive, a full roof replacement can cost upwards of $10,000 and a lot more on a larger building or commercial roof. Therefore, some property owners decide to go to a local roofing contractor who would charge for less. Which in many cases result in having a local roofing contractor who is unlicensed. Unlicensed roofing contractors are often likely to be less expensive than those who are properly licensed and insured.

Unfortunately, taking this kind of financial shortcut with choosing a cheaper contractor could cost you a lot more than you realized. Therefore, when choosing a roofing contractor the first thing that you should do is make sure that they are licensed. Contractors who don’t have the proper training, knowledge, and expertise to be working on roofs may try to take roofing jobs without a license because they don’t have the necessary skills to become licensed. Going with a contractor like this means that you would be trusting your roof with someone that is going to do an inferior job. Poor workmanship often leads to more expensive repairs down the road where you need to have the original work redone. Depending upon where you live, hiring an unlicensed roofing contractor could also land you in hot water legally as well. If your unlicensed contractor fails to complete the job, you may be prevented from using them. And in some states, hiring an unlicensed roofing contractor can carry fines up to $5,000 as well, which could lead your cost-cutting techniques to backfire in a big way.

Lack of Certification

Many manufacturers that provide roofing products and shingles, such as GAF, offer certification to roofers. When a local roofing contractor has certification it means that the roofer has learned the necessary things to properly install their products. This often makes them a candidate for offering extended manufacturer’s warranties. A roofer who isn’t taking the time to get a proper state license would unlikely follow-through on a manufacturer certification as well. Therefore, it’s more than likely that you’re hiring an amateur who is untrained in installing the specific roofing materials that they are putting on your roof. And if something were to go wrong, you won’t be covered by the extended warranties that can help give you peace of mind and offset the cost of future repairs.

You may be liable for unpaid bills

Unlicensed local roofing contractors typically may fail to pay their subcontractors or their suppliers after the work is done. Unfortunately, that may leave you in the position of needing to pay them, even if you’ve already paid for the work in full. This can result in a lien being put on your property until you settle the bills. Remember, you often can’t take an unlicensed roofing contractor to court, so you have no recourse to pursue him if he doesn’t pay his bills.

Mechanic’s Lien

A lien is a notice attached to your property informing everyone that you owe the creditor money. It may seem essentially unfair that you can possibly end up paying for the general contractor’s irresponsible behavior. The justification for allowing the mechanic’s lien in the first place is that between the person with an improved property which would be you the homeowner and the person who supplied your new roof, the supplier’s need to get paid is greater. The law also concludes that you can, in turn, sue the general contractor. While this is true, this doesn’t really help you in the short-run. Suppose a supplier places a mechanic’s lien against your house because the general contractor failed to pay him when the general contractor lost all his money. You can certainly go file a lawsuit against the general contractor, and over time maybe garnish his wages or force him to sell his property, but that takes time and wringing money out of someone who doesn’t pay his subcontractors and suppliers can be difficult. Meanwhile, you owe twenty thousand dollars and have a matter of days or months to pay the supplier or else your house will be sold to satisfy the mechanic’s lien against you.

How do you protect yourself against a mechanic’s lien?

Here are three ways to help protect you and your investment:

Make sure you have a list of all the subcontractors, laborers and material suppliers that your primary contractor will be using, and ask for proof that everyone has been paid before releasing your final payment, otherwise you could be held liable.
Before making any partial or final payment to your contractor, ask for a Release of Lien or Partial Release of Lien and Affidavit. This just simply means that it reduces the amount claimed to be owed. These will either indicate that the contractor has paid all laborers or list out who is still owed money and how much. If you pay the subcontractor or laborers directly, make sure to get a release of lien.
Even if your state doesn’t require a written agreement, ask for one. Also, keep in mind that contract requirements vary by state. It should be clear and concise and include the who, what, where, when and cost of your project. It’s not a bad idea to have an attorney review the contract before you present one or sign one.

Can a homeowner file a lien against a contractor?

Not all mechanic’s liens that contractors file against a homeowner to secure payment are right. Sometimes, there can be a genuine dispute between the contractor, subcontractor, and/or owner about what exactly is owed and due. However, there are some instances where there is a subcontractor, contractor or even a supplier who exaggerates the amount of the lien that they filed. There can be a case where the lien amount is intentionally exaggerated, or filed with no legal basis. When dealing with a frivolously filed mechanics lien, there are some states that have legislation that specifically prohibits willfully exaggerated liens. New Jersey for instance, has a statute that creates liability for those who file such liens. They can face damages and penalties, and their lien can be stricken.

No permissions or permits

If a local roofing contractor is willing to work without pulling a building permit or completing the proper inspections, he’s not doing so to save your time or money. It’s typically because he is not qualified to pull the roofing permit, or he knows that he is doing sub-par work that won’t pass inspection. Whether performing re-roofing or new construction, when a contractor does not pull permits you are at risk for penalties, code compliance issues, possible tear out, the cost of rework and potentially the loss of a home sale. Depending on the type of roofing job, and whether the homeowner chooses the do it yourself option or hires a contractor, certain scopes of work will require construction permits. Failure to obtain necessary construction permits by either you or your contractor may become a safety issue or an unexpected expense far in excess of the cost of the original building permit.

When you hire the wrong contractor the majority of the time they don’t pull permits for the scope of work required and so the homeowner becomes the responsible party, often with no penalty to the hired contractor. The local governing authority establishes how penalties are assessed. For instance, penalties can range from charging a homeowner double the original fee for tearing out the complete work for an inspection. While passing off unpermitted renovations to a potential unsuspecting home buyer is nothing new, the seller’s maneuver will often be exposed by a qualified home inspector. If discovered, you may be required to provide evidence of valid permits for the work on a file with the local governing authority.

While a reputable contractor will complete the necessary steps to obtain a building permit and local city, county, or state permission for the jobs completed, an unlicensed contractor won’t. This can mean major problems down the road should you decide to sell your home. Even if you don’t sell, you could be held liable should something bad happen on your property due to faulty and illegal construction practices.

How to Help Prevent Roof Fires & Fire Damage

January 15, 2020 by Infinite Roofing 1 Comment

We understand that fires are one of the most unpredictable hazards that can happen in a home. We also understand that no one can prepare for everything that could come at them in life, but we like to think that these few tips on how to help prevent roof fires and fire damage could potentially save some sanity. These are not foolproof techniques that guarantee that no fire will happen in your home, but they are necessary steps that help decrease your risk for a roof fire and should be taken into consideration when inspecting or installing your roof.

Many may think that their roof is only the finishing touches that they need for their home, however, that’s not true. Your roof protects you, your family and everything that you own and is an essential piece to your home. If your roof becomes damaged, however, then it is not going to be able to provide that much-needed protection. As a homeowner, you should remember that roof fires can seriously damage homes and is an extreme threat to you. Fires often start without warning, as most attics do not come with a smoke detector installed. Let’s talk about how you as a homeowner can take the proper steps necessary to protect yourself, and your home from fire and the damage that comes with it. Here are the most important tips for preventing roof fires and limiting the potential damage caused by a roof fire:

Keeping Your Chimney Clean

If your home has a fireplace, then perhaps one of the most important steps you can take towards preventing roof fires is to clean your chimney regularly. Over time, a combustible layer of material known as creosote will start to form inside the chimney, which can easily catch fire if ignited by a spark. Creosote is simply a dark brown or black flammable tar which is deposited from wood smoke on the walls of your chimney. During the wintertime, your fireplace is used quite often, therefore, this material can build up quite frequently and leave open the possibility for a fire. It is highly recommended that your chimney is cleaned at least once a year before the start of winter so you can avoid any future fire damage.

Inspect Electrical Wiring / Leaky Roof

Electrical wiring is the leading cause of attic and roof fires. Usually, the number of cases of these fires is higher in the months where there is an increased use of light and heating appliances. It’s highly recommended having your electrical wiring inspected by a professional, especially if your home is an older home, or if you suspect that your home may have faulty wiring. We suggest that you keep a lookout for signs of flickering bulbs and light fixtures that unexpectedly fail to turn on. The reason is that these problems can be caused by burned wires in your attic and one wrong spark could be problematic.

Roof leak repairs should also be a major priority since water damage is a potential fire hazard. Roof leaks can lead to electrical malfunctions in the attic as well as leading to wire shorting issues. Many may expect the wires that are protected by junction boxes and insulation materials to be completely safe, however, that is definitely not the case. It is possible that water can seep around the hinges of a junction box or insulation clumps when left exposed to water. Be aware that if a live wire comes in contact with water, it can cause a spark and ignite the materials around it. So make sure you have any signs of water damage inspected by a certified roof inspector.

Ceiling Insulation

You may see ceiling insulation and might automatically think that having ceiling insulation is a fire hazard. Well, this isn’t necessarily the case, fire hazards in the ceiling are not caused by the insulation itself, however, it is caused by the way it was installed or the way an electrical cable was installed alongside the pre-existing insulation. When you’re getting your roof or ceiling inspected, investigators would look to see if your roofing material property is lacking sufficient insulation around the vent pipe for generators. Roof fires can be caused by a lack of sufficient insulation around the vent pipe and when that happens, the heat coming from the vent pipes deteriorates the roofing material over time. In return, in combination with high winds, an event like this would ignite a fire causing critical fire damage to your roof and home. A roofing contractor should ensure that your ceiling insulation is not fitted too close to a heat source, which will also ensure your home’s fire resistance.

Choose a Fire Resistant Roofing Material

Before choosing a fire resistant roofing material, you should understand what it means to have a fire resistant roof. Roofing materials are categorized to their relative fire resistance because it helps roofing contractors distinguish the safety level of the different fireproof materials. Depending on how flammable your roof is will determine how much fire damage a roof can withstand, therefore, the type of roofing material you choose is critical when thinking about the fire resistance of your roof and home. Roofing materials come in different fire resistant classes, with Class A being the most fire resistant.

Depending on your roofing material, it will determine how flammable your roof is and how much fire damage it can withstand. Roofing materials come in different fire retardant classes, with unrated or C being the lowest class, and Class A being the most fire resistant. If your roof is getting up there in years and it’s almost time for a replacement, then make sure that your new roof is installed with Class A roofing materials. If you live in an area that is prone to wildfires, then you should also consider a fire resistant underlayment. Your local roofing contractor will be able to let you know what your options are and what material will be best for your roof and safety.

Now you may be wondering what are the most fire resistant roofing materials. The resistance to fire for roofing materials is rated based on a series of test that is defined by a fire rating. A reliable roofer will be able to find the right option to match your style and budget while maintaining your safety. There are a few different materials on the market that are effective in withstanding fire damage.

Before getting into the different fire resistant roofing materials, we should understand how the fire ratings work first. Knowing what the fire rating for roofs is about will help you better understand when choosing the right fire resistant material for your roof. As mentioned before fire ratings for roofing materials are classified as either Class A, Class B, Class C or are unrated if a roofing material cannot meet the requirements for any of the classifications. Class A is the highest fire rating, offering the highest fire resistance, and unrated being the worst. Examples of Class A roof coverings include concrete or clay roof tiles, fiberglass asphalt composition shingles, slate, and metal roofs. An example of an unrated roof covering is an untreated wood shake roof. If wood shakes and shingles are saturated with fire retardant chemicals, they meet the requirements for a Class B fire rating and can meet a Class A rating if additional materials are included in the roof’s assembly.

A standard fire test is used to determine the fire rating of a roof covering material. This test evaluates the following performances:

Flame penetration through the roof covering into the attic space
Flame spread over the surface of the roof covering
And the propensity for the roof covering to become dislodged and generate embers.

Metal Roofing

Metal roofing is made of a material that does not ignite when on fire with a fire resistant barrier with a Class A protection. Most metal roofs are made of steel, zinc, copper, and alloys that are best for a dry environment. The benefit of metal tiles is that they are non-corrosive and sit strong on houses with a steep slope. If you have the budget, metal sheets can be designed to look like cedar shake or other materials while maintaining its fire resistant properties. Metal roofing is one of the few roofing materials that are truly fire resistant.

Concrete / Clay Roof Tiles

Clay is inherently fire resistant and can easily disperse heat. When the material is installed properly it achieves a Class A fire safety rating. Many homeowners usually don’t go with clay tiles because it’s a tad more expensive compared to shingles, however, clay tiles are still affordable. They are also extremely durable and have a good lifespan. Clay roof tiles are also known to withstand extreme weather conditions including high winds. The curved shape of the clay tiles allows for ventilation. Therefore, hot air isn’t trapped by clay tiles during hot temperature events, and their heavy thermal mass helps insulate your home during colder temperatures. Concrete roof tiles share most of these properties as they are also heavy, durable and fireproof.

Fiberglass-Based Asphalt Shingles

Asphalt shingles are a commonly used roofing material. What you should know is that the shingles you typically find on your roof are normal asphalt shingles, which are fire resistant on their own. Now, when it’s combined with fiberglass underlayment the structure becomes even more fire resistant making it a Class A fire rating. Plus, asphalt shingles require little maintenance and are quite durable. Though it requires less maintenance, it is important to take care of this type of roofing because of the fact that heavy winds can blow off the shingles which in the end would leave exposures in your roof that can make the roof vulnerable to water and fire damage. Keep in mind that although asphalt shingles are fire resistant, they are still flammable. They will withstand an external fire very well, however, if the fire happens to start on the inside of the home the fire is very likely to reach the roof and the shingles may burn.

Slate Tiles

Slate, although it is a heavy and thick roofing material, it’s naturally resistant to fire. The thickness of the material is part of what helps it achieve Class A rating because it’s not easily chipped where fire can penetrate through. Slate is a lot more expensive than asphalt or metal, but slate will last you a very long time and maintain your home’s protection throughout its life.

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.

New Year’s Roof Resolutions

January 1, 2020 by Infinite Roofing Leave a Comment

The Infinite Roofing Team is reminding homeowners and business owners of the importance of the roof over their heads. Your roof is one of the most important parts of your home or business, both aesthetically and functionally, so it makes perfect sense to keep a close eye on it to keep it in good health. We’re recommending that you add your roof to this year’s list of important New Year’s Resolutions.

Scheduling A Professional Inspection

Most homeowners and business owners are unable to spot faults on their own in a roofing system until it’s too late or until water has penetrated the surface. Therefore, by scheduling an inspection with your local roofing contractor, they can help pinpoint any potential problems before it is too late. The point of having a roofing contractor is so that they can provide a complete and thorough inspection of your roofing system. As a homeowner possibly without very much roofing experience, it would be much harder for you to spot any problems than a trained and experienced professional. A professional roofing contractor could find any leaks, roof membrane damage, and membrane deterioration. Your local roofing contractor can also give you advice and recommendations on how you can improve the safety, longevity and durability of your roofing system.

Think of a roof inspection as a preventative measure that could save you thousands of dollars in per year. A professional roof inspection can reveal structural weaknesses in your roof, deficiencies, or damage that can lead to much more expensive roof repairs if left unchecked. A roof inspection also includes a thorough check-up of your home’s ceilings and interior walls for possible water infiltration such as ceiling tile stains, incorrect roof flashing, excessive debris, and curb or pipe penetrations. A comprehensive roof inspection can catch membrane deterioration early and have it fixed, if possible.

Make your new year’s goal, getting your roof checked at least twice per year! Some warranties won’t be completed without a thorough roofing inspection by a reputable local roofing contractor. Roof penetrations and incorrect flashing could potentially void the manufacturer’s roof warranty. Deterioration and damage can lead to premature roof leaks and cause serious emergency situations or disruption to your property. Preventative action always pays off! Therefore, we strongly recommend that you make scheduling a professional roof inspection a New Year’s Resolution.

Keep An Eye On Your Gutters

It’s critical to keep your gutters in working order to allow water overflow to drain from your roofing system. You want to ensure that water flows away from your roof without pooling in corners. You can also check your gutters to find out if you have significant and threatening shingle or tile breakage as well. The role of gutters is to route rainwater away from your home. It can be difficult for homeowners to identify minor gutter issues before they become full-blown failures. Neglect leads to clogs, which can cause leaks in the gutters. These leaks typically form at the joints, at the areas where gutters lengths and downspout meet. These areas are often sealed using a sealant, which can get worn out due to weather exposure. Gutters will also tend to overflow if clogged, so cleaning them regularly at least twice a year is important. Holes from rust spots are yet another source of leaks and can develop from the smallest exposed metal surfaces.

Water pooling around your home’s foundation is the biggest risk you would face when neglecting your gutters. This weakens the ground that the foundation sits on, which could cause the house to settle inappropriately. Also, your home’s foundation is made of concrete and concrete absorbs water. Water pooling around the foundation due to faulty gutters can weaken the foundation, causing irreparable damage. The fascia boards that hold the gutters in place could get damaged as well. The exposed wood will begin to rot if soaked in water. Gutter hangers could come loose, necessitating a complete gutter replacement.

Replace Missing Shingles Or Tiles

If your home or business has loose or missing shingles or tiles, you may wind up facing much more than an aesthetic problem. With missing or damaged shingles or tiles, your roof is much less likely to remain weatherproof.

When shingles from your roof fall from their adhesive backing or nails give out, they leave the insulating and adhesive layers open to the elements. This exposure can cause roof leaks, structural damage, weatherproofing damage and dry rot. Even if the open patch of a roof is small, average amounts of rainfall are enough to soak the layers between the exposed area of your roof and the inside of your home. Unwanted wetness in your home will cause roof damage as well as weaken floorboards, soak the insulation, and let moisture into your foundation.

Over time, the water from roof leakage can weaken your home’s structural beams and foundation, causing much larger, permanent problems. If your support beams fail to provide support for the weight of your house, you may experience foundation cracking, roof caving, and wall breakage.

Dry and hot as well as frequently changing weather conditions will stretch, condense, and water down the weatherproofing and adhesive layers beneath your roof tile. After these layers are exposed to dry air and direct sunlight due to missing shingles, they will lose their protective properties.

In hot weather areas, unprotected parts of your roof will experience dry, scorching air throughout the entire day. The air saps the moisture from places that need oil and moisture to function properly, causing them to expand without pliability. They will crack and weaken, leaving them vulnerable to breakage. These problems can also occur in combination. When they do, small problems with over-dryness or excessive moisture can cause much larger problems for the entirety of your house.

Since residential and commercial roofs in the region have to put with so much constantly changing weather, the cause of slipped, broken, and missing roof tiles or shingles can be one of a combination of the following:

Wind – Even if your roof is built with consideration for wind damage, strong, gusting winds can still pull shingles from their place if the come with enough force.
Trauma- Unusual weather events such as hail, rainstorms, or blizzards can pull tiles from their place. Tiles will slowly weaken and break from too much impact.
Dryness- Most types of roofing require moisture to stay weatherproof and secure. Droughts and severely hot weather will pull that necessary moisture from the tiles.
Weakening- Underlayment and sheathing underneath your tiles will start to give in to the elements over time. This allows your shingles to slip and opens them up to damage.

Consider Roof Cleaning

Cleaning your roof not only helps to please the eye, but it also helps in keeping it in efficient working order. Eliminating leaf and debris buildup can reduce the risk of mold and mildew that can seriously threaten the functionality of your roofing system.

Roof cleaning is commonly overlooked, however, when the siding of your home is dirty or the paint is peeling, it becomes an obvious sign that it is time for maintenance. However, the roof of your home tends to be a bit more out of the line of sight. As they say— “Out of sight, out of mind”. What many homeowners fail to consider is that a roof that is not properly cleaned and maintained can lead to damage which will shorten the lifespan of perhaps the most important protective feature of your home.

Your roof is exposed to the elements all day, every day. Dirt and debris will collect on it. Natural rainfall is typically enough to wash off the appearance of most superficial dirt. However, the dark stains and green areas that appear on your roof are caused by other natural elements. Some of these elements are algae, lichens, and moss.

If you have ever noticed any black stains on your roof, these stains are a growth called algae. Algae feed off both asphalt and limestone roofing in moist, cool and shaded areas of your roof. When there is minimal light, algae forms a blue-green color. The more shaded areas of the roof are more likely to have this algae, which can also harbor various types of molds. This explains why some roofs are stained only on one side. These algae spores are transported by wind or animals and can quickly spread from rooftop to rooftop in neighborhoods of single-family homes, townhomes, apartments and commercial complexes.

Lichens are essentially a combination of algae and fungus. Lichens are a fungus that grows along with algae. These plant-like organisms from a branching growth of root-like tentacles that penetrate deep into the shingle’s base for nourishment. Lichens are tough to remove from the roof and can reappear from humidity and rain.

Unlike algae and lichens, moss is an actual plant. Moss has a shallow root system and requires a lot of moisture to survive. Areas with less sunlight remain damp longer. Overhanging tree branches not only provide more shade, but they also drop debris that serves as a food source for moss. Like algae, moss spores are often transferred by wind or animals and can easily spread throughout neighborhoods.

The staining and growth patches caused by algae, fungi and moss can damage your roof through shingle deterioration and wood rot. Both lead to expensive repairs and can shorten the life of your roof. A thorough, professional roof cleaning can help minimize or reverse this damage.

Use these top roofing tips to get the year started right. Happy New Year from the Infinite Roofing team.
