Should metal roofs be grounded?

by Leave a Comment

When you decide it is time for your home or commercial building’s roof to be done, you have many options available to choose from. Shingles, rubber, and metal are among the most popular choices of roofing materials, and each tailor to different needs. Shingles take the lead for most sought after roofing material on residential homes but metal is becoming a popular choice. Metal was reserved for warehouses, factories, and sheds in the 1850’s, and in recent years people have been enjoying the sleekness it adds to their homes.

Metal roofs offer a long list of benefits that include its longevity of 40-70 years, a wide range of colors, its durability, energy efficiency, and value it can add to your home. Of course with all the positive attributes a metal roof adds, there are some cons to think about. The cost of labor, insurance, and materials have gone up and continue to rise each year. What does this mean for you? Well a metal roof is expensive, but if you are looking for a roofing system to install once and not have to ever again, then a metal roof is for you.

The reality is that no matter what you choose for a roofing system it will be costly, so it’s best to figure out how to get the most bang for your buck, and the most years. Seeking out the best roofing company in your area that specializes in metal roofing is a must. Metal is more complex than laying down shingles so you don’t want to cheap out on a roofing crew that doesn’t know what they are doing.

Now that you have weighed all of your options and finally chose a metal roof for your home, you may have some questions or concerns. Lightning strikes on a metal roof may be a concern of yours, as it is of many others who are thinking about installing metal on their homes. After much research it has been established that a metal roof is not more likely to attract lightning than any other roofing material. In fact a metal roof is thought to be even safer than other choices because of its non-combustible highest class A fire resistance rating. Metal roofs are most popular in lightning prone regions because of their fire safety.

When lightning strikes a building, it channels through the material and works its way to the ground, through a home’s pipes and electrical systems. If a roof is covered in combustible material such as flammable asphalt shingles or wooden shakes, lightning can ignite them. Comparing these materials to metal, there is just no chance of that occurring because of its fire resistance rating.  

What is grounding?

Grounding is to provide an alternative pathway for an electrical surge of electricity when lightning strikes a roof or another surface. When a metal roof is installed on a residential home, a grounding system can be formed with copper wires that are attached to each electrical box in the home, this is done to ensure that the current is dispersed. When choosing the best roofing company for the job, ask them if they have experience in grounding metal roofs or installing conducting rods. Most reputable roofing companies agree that metal roofs do not need to be grounded, and is not a necessary step.

There is no building code that requires a homeowner to ground their metals roof, assuming that all other building codes are in place. Including the use of PVC for piping to extend out of the home being strictly followed. We can all agree that metal is definitely an electrical conductor but what’s more important is the type of roofing materials that are being used. If lightning were to strike the metal roof of your home it would be grounded throughout the entire roofing structure, and no damage would be done to the roof or your family. There is no reason to be afraid to place a metal roof on your home, they are beautiful and will last almost as long as your life.

A lightening protection system (LPS), is a rod or lightning conductor made from metal and mounted on a housing structure or building to protect it from lightning strikes. Placing this rod on top of a structure will advantageously strike the rod and transfer the energy through to the ground instead of passing through the building itself.

If you think you live in an area with high amounts of storms you can take this risk assessment to ensure the protection of your metal roof and building. This assessment enables the consumer to make better informed decisions to meet the expected building requirements of safety. Lightning protection is not mandated by the national building codes, but it is required in some local codes and certain governments.

Shingles

Shingled roofs are the most common roofing material on the market in North America, covering about 85% of homes. Shingles are usually made of asphalt but there are other options you can choose from. Architectural shingles are the go-to for shingle roofs because they are much thicker with an appealing textured appearance.

There is variety of shingle types, colors, and patterns to choose from to make your home stylish.

Cons

Shingle roofs have the shortest life expectancy from about 20-35 years, this may not be as appealing to you as other materials that can last upwards of 70 plus years. Shingles can also only be installed during certain seasons, if you live in the New England area winters are a factor. The freezing temperatures and lack of sun will hinder the process of the roof installation.

If you are having your roof replaced in the winter season because of major issues, freezing temperatures can easily damage shingles and cause sealing problems. The cold makes shingles more susceptible to lifting and cracking. Although it is possible to have your roof replaced in the winter months it is always best to wait until temperatures are more favorable. Looking for the best roofing company in your area to make sure the job is done correctly, especially during the winter season is important.

Metal

Unlike shingles, metal roofs have a life expectancy of about 40-70 years. Metal is a fantastic choice if you are looking for a long term solution for your homes roof. You can easily identify metal roofs by their sleek, large interlocking panels. Metal is the most expensive option so be sure to seek out the best roofing company in your area to do the job.  

Pros

The most obvious appealing quality a metal roof possess is its long term life expectancy. If you are looking for a roof that will last as long as you own the house or even out-live you, metal is your best bet. Metal roofs do not absorb as much heat as a shingled roofs which makes them much more energy efficient. You can save up to 40% on your energy bills during the summer months by switching to a metal roof.

This type of roofing system is made up of 25-90% of recycled materials, making metal roofs the most environmentally friendly option. There are a wide range of styles and colors to choose from, so you don’t have to sacrifice the appearance and style of your home.  Fire resistance is another great feature that a metal roof offers, they won’t ignite if a fire breaks out or a lightning strike occurs. Metal is very durable in all types of weather conditions, including heavy snow and salt water areas.

Cons

The cost of a metal roof is more expensive than the other options and its installation is more complicated. Metal roofs require specialized tools and extensive knowledge to install, consulting with a qualified roofing contractor that excels in metal is important. Noise can be an unattractive feature especially during heavy rain or hail storms. Adding more insulation during the installation process can help. The materials used in metal roofs tend to contract and expand, if they are not installed properly the panels can loosen.

Slate

If you are looking for a roofing system that offers a “lifetime” of superior durability and a distinctive touch of timeless beauty, then you should consider slate. Slate shingles are made from natural stone and are commonly used on sloped roofs. This roofing material has been around for hundreds of years and is the most durable. The life expectancy of a slate roof is between 70-200+ years!

Pros

The longest life expectancy of any roofing material is slate, some reports even show roofs lasting as long as 200-300 years. As long as the stone is good quality it will last many lifetimes. Slate is high in density which makes it fully waterproof. This material is also resistant to any temperature fluctuations or inclement weather conditions, making this material ideal for areas with heavy rain or snow falls.

Another benefit to a slate roof is its properties that make it mold and fungus resistant, meaning little to no maintenance for you. The installation of a slate roof on a house greatly increases its value, and resale potential. The longevity of this material makes this the most environmentally friendly roofing system.

Cons

Because slate is formed naturally there can be variations in the rock which affect its quality. If the iron content is too high then the rock can shale, splitting into many tiny pieces. Slate is also very heavy, which is great as a roofing material but difficult to install. This is the most complicated material to install, requires special equipment and extensive knowledge to only be completed by a qualified roofing contractor. It is imperative to find the best roofing company in your area that has experience in dealing with other material besides shingles.

Wood Shakes/Cedar

A wooden or cedar roof is made up of overlapping wooden tiles, not known for its extensive longevity but a certain look that people are going for. Wood may not last as long as asphalt shingles, metal or slate but it does offer a variety of attractive qualities.  

Pros

Cedar roofs have a very high resistance to wind, temperature variations, and are eco-friendly. Their energy efficiency provides two times the amount of insulation compared to asphalt shingles. Although cedar tiles are not as long-lasting as the other materials, they still hold a lifespan between 30-40 years. Most people who install wood roofs choose them because of their aesthetic appearance.

Cons

This roofing material is not the cheapest to install, and it must be specially treated with a fire retardant. Wood is extremely flammable and some neighborhoods no longer allow cedar shingles as a fire prevention measure. Cedar shingle roofs also require more maintenance than asphalt shingle roofs.

Rubber

Synthetic rubber, well known as EPDM (ethylene propylene diene monomer) is a durable roofing material used on commercial buildings. If you wanted to install EPDM on your home, it would have to meet certain requirements to be install properly. This material is very durable, cost effective, and requires little maintenance.

Pros

Rubber roofs are less susceptible to leaks compared to other roofing materials, and have little maintenance because they are waterproof. If a leak does occur it is fairly simple and cheap to fix. EPDM is recycled after its lifespan making is an environmentally friendly roofing material. It is also very durable and can withstand high winds, ice, snow, and hail, along with the suns UV rays.

Cons

The biggest drawback of a rubber roofing system is the installation obstacles and inexperienced roofing contractors. Where HVAC units, chimneys, and other roofing features meet, become culprit too future leaks if not done correctly. When Considering EPDM for a large commercial unit or home it is important to find the best roofing company in your area that is welled experienced in this roofing material.

What are the best roofing systems? How are they trending?


Mixed Material Roofing

There are a lot of popular and latest roofing trends. One of them being mixed material roofing- combining metal and shingle roofs is one of the latest architectural trends. Some homeowners may realize that standing seam metal roofs and flat seam metal roofs are consistently one of the popular choices for reroofing and new roofs. The newest metal roofing trendsetter is a Hybrid Metal and Shingle Roofing System. The combination of metal roof panels and laminated shingles on separate pitched roof sections delivers the visual bang of a metal roof at a much lower cost. 

Solar Panels and Solar Shingles

The rise in the popularity of solar power has people continuously expressed a desire to have more options in terms of solar products. The average homeowner is starting to wonder how much solar could save and how simple making the switch could really be. Increasing your home’s energy efficiency, minimizing your carbon footprint and saving on your energy bills makes going solar very appealing to many people.

When solar panels first became available, they had a very clumsy appearance, lack of energy efficiency and were extremely expensive. Making the switch back then just did not seem worth it. Eventually, technology development has allowed solar roofing to become a much more legitimate option for residential homes. Modern solar panels look very stylish and striking, are very energy efficient and are now much more affordable.

The cost of these materials has fallen dramatically in recent years, although it is still by no means a cheap solution. However, as the technology continues to improve, you can expect the benefits to increase and the costs to go down even more. New York is also one of the top states in the country for offering considerable state and federal solar incentives.

Cool Roofing

One of the latest trends local roofing companies get asked about is cool roofing. It is a relatively new technique. Cool roofs have the ability to reflect the visible, infrared and ultraviolet wavelengths of the sun, therefore reducing the heat transfer to the building.  It also has the ability to radiate absorbed, or non-reflected solar energy. The best thing about this technique is that it can be applied to a variety of roofing materials, colors, and designs to not only enhance curb appeal but also fit your unique style. A cool roof can significantly improve your energy efficiency, reduce your power bills and reduce wear and tear on your HVAC system. It can also make being inside a lot more comfortable.

Metal Roofs

As a top local roofing contractor, each year we’ve seen a steep rise in the popularity of metal roofing materials. This is definitely a trend we’ll be seeing more of in 2020 and beyond. Due to its aesthetic appeal and functionally, various homeowners with different home types request for metal roofs. 

Metal roofs give homeowners a chance to achieve the exact look that they want for their homes since there are a lot of styles, types, and colors to choose from. Metal roofing is stylish and able to mimic other expensive materials through metal shaping and finishing. Also, the metal roof still has a long lifespan without needing any regular maintenance. While the initial expenses for its installation can cost two to three times more than asphalt, homeowners can save money long-term as the highly reflective and insulative aspect of metal roofing reduces heating and cooling costs.

As many people are highly concerned with the environment, metal roofing materials such as aluminum and steel hold much appeal as it contains high percentages of recycled content. Aluminum roofs are also 100 percent recyclable, so there’s no need to worry about roofing materials being dumped in landfills. Thanks to its incredible durability, a metal roof is also a great choice for homeowners concerned with storm damage and costly roofing storm repairs.

Designer Options

This is a varied approach that’s not limited to a single style, material, or design. Instead, a designer roof is one that is built with specific qualities. Live in a storm heavy environment? A designer roof can be installed with storm protection in mind. Live in wildfire heavy areas? Roofs that are fire resistant are available to meet your needs. This is one trend that won’t go away thanks to its high level of customization and sustainability. 

Concrete

Today, homeowners want style, texture, and above all durability so they don’t have to worry about costly roofing repairs. With concrete tiles, those desires are easily satisfied. Although extremely heavy, the tiles are incredibly durable and versatile.

Green Roof (or Living Roof)

A more uncommon option right now, but one that is continually growing in popularity, is the living roof. We all know that moss, fungi, and other plant life are hazardous to the roof’s health. However, with professional installation, you can actually have plant life as your roof’s visible exterior, thanks to the protective materials underneath. Homeowners are finding this option saves them money on their energy bill thanks to the extra insulation provided with this roofing choice.

These green roofing systems are easy to distinguish with their multiple layers of engineered soil, protective fabric, a waterproof membrane, and a layer of vegetation to top it all off. The plant life doesn’t just add to the overall aesthetic of your property, it also comes with a multitude of benefits for your home and environment. 

Green roofs can be more expensive to install, but they can save you money in the long run. Their insulating properties lowers your home’s electricity bill, and they require very low maintenance. Green roofs work best on a sloped roof where if it storms, plants can absorb some water and drain the excess.

Synthetic Materials

The traditional asphalt shingles are desirable because they’re cheap. Slate, shake, metal, and other sturdier materials are much more expensive. Synthetic shingles made out of recyclable materials such as plastic and rubber are today’s best choices for more sustainable roofing that’s eco friendly. The material can be shaped and designed to look like the more expensive options, but at a fraction of the cost. In addition, the energy efficiency and overall of the product is nothing to scoff at. 

With the roof playing such an essential part of the home, it’s no wonder that people are always looking for ways to help it stand out. After all, just because a roof is meant to protect your home, doesn’t mean it can’t look good too. This idea has led to some new and innovative roofing possibilities. You may notice that some of these trends that will be listed were popular in the year 2019.

Asphalt Shingles

For decades, asphalt shingles have been the roofing material of choice for many homeowners, and it’s still going to stay by 2020. Asphalt is a sturdy material with a long lifespan and withstands even the most severe shifts in weather. But besides its excellent performance, these shingles have always been popular because of its affordability. 

While they don’t last as long as metal roofing, a good asphalt roof can still last for a long time. Just perform regular maintenance to increase its lifespan for even longer.

Lighter Colors 

Gone are the days when people should favor a dark colored roof over a light roof. Some people may be tired of having to look at dark, drab roofs all the time. Also, recently roofing manufacturers have become increasingly aware how much dark colors absorb rather than reflect the sun’s rays. Lighter colors are much better for your building’s energy efficiency. Lighter roofs cost less to cool and you have more control over the heating process. The longevity of the roofing materials can also be increased, since the sun’s UV rays can be destructive over time.

This means such roofs are emerging as a very popular style choice as well as an economical one. Many roof shingles are being produced in shades of soft greens, warm blues, and even neutral colors like taupe, beige and off white. While dark neutral or brown tones will never go out of style, light colors have been gaining popularity every year and are expected to gain more traction for the years to come. However, if you still prefer a dark-colored roof, you can still just add a hint of color to your roof without turning it into a terrible eyesore.

Residential Flat Roofing

As modern styles become more and more popular, local roofing contractors are now seeing flat roofs have also entered the trends for residential homes. Their style perfectly fits into the minimalistic approach many people are favoring these days.

Flat roofs are generally less expensive compared to other roof types and offer more design choices. You can also add solar panels and turn it into a green roof without too many additional expenses. Additionally, they’re easier to install, safer, and more accessible than any other roof type. It’s also possible to utilize a flat roof as an additional living and recreational area for you and your family.

Commercial Flat Roofing

by Leave a Comment

Making a decision on what type of commercial roofing system you want to have or replace on your current commercial roof, there are many options to choose from. Therefore, trying to decide exactly what you want can be extremely stressful especially when you do not know a lot about commercial roofing. So the question you should ask is, how do I decide and what should I consider in order to make my decision? Well, for starters, flat roof systems have different types of roofing materials for your needs and budget. Therefore, you should consider each of the advantages and disadvantages before making any final decisions. You would also need to consider where you’re located, the use of the roof, your climate, and roof maintenance. Therefore, when considering buying a commercial flat roof system you need to know the materials that you want to go with. There are five types of commercial flat roofing materials that are the most commonly used on modern commercial flat roofs. These five materials are EPDM roofing, TPO roofing, PVC roofing, metal roofing and modified bitumen.

Some factors that you would want to consider when purchasing a new commercial flat roofing system is price. Price is one of the biggest factors many building owners and residential owners consider when purchasing a roofing system. When you’re basing your decision on price, take into consideration if your roof will need any extra attention or expense after the initial installation. For instance, your new roof may require regular maintenance and repair. Some roof types require far more maintenance than others do. Therefore, if you have a budget in place, you will want to consider how much you will be paying for a regular maintenance program to keep the roof running in good shape. Modified Bitumen roofs, for example, require frequent roof maintenance compared to EPDM, TPO or PVC roofs. Another thing is the price of any repairs, so you should ask yourself the question, is this roof system easily repairable and how quickly would it need to be repaired? This question should be based on your roof use, roof material and weather conditions in your area.

Now, if the system that you choose or already have is not one that has a long lifespan then you will most likely have to repair it within a ten year period. Especially if it requires frequent maintenance and repairs. Now, which one is going to cost you more annually? Is it going to be the flat roof that does not usually have a very long lifespan and requires more maintenance? Every roof system needs to be maintained, however, the amount of time and the cost to maintain it can vary quite a lot. Therefore, consider what the roof system may cost you on an annual basis over its lifespan. Hiring a commercial roofing contractor that has experience in commercial flat roofing can be a useful source of advice to help you make the right choice. The majority of the time the cheaper roofing material can be the most costly in the long run, when you factor in the cost of regular repairs and maintenance.

Another factor that you want to take into consideration when investing in a new commercial flat roof is the quality. As mentioned before, some roofs last much longer than others because of the maintenance requirements, the lifespan of the material, the roof itself and how it is used, and even the location of your property. So you might ask yourself; what is the quality of each roofing material you are considering? Is the material reinforced? Is it flexible? Is it a well-known brand? Is it durable enough for my roof?  You’re going to want the quality to be high, affordable and you want to know if its performance truly meets your expectations.

The qualities that you would want to look for are durability, lifespan, sustainability, reputation, the characteristics of the material and so on. You want to ask, what puts that roofing material above the others?

Prefabrication is another factor to consider. Prefabrication generally means the material is fabricated at the manufactures so when applying on the job site, it would consist of more focus on installing the system than having to go through the full process of measuring, cutting and welding. The product would come pre-fitted for your roof which can take away from the labor costs to install and the roof can be installed much faster. This can help minimize disruptions to your business which can be an important issue in any commercial roof installation process.

Metal Roofing

Metal roofing is different from most other commercial flat roofing materials for a few reasons. A metal roof is an ideal choice with a roof slope that is greater than 2 inches. Metal roofs are mainly favored by facility managers because it is extremely durable, non-combustible and is able to reflect heat off your roof. The surface of the metal roof can be extremely hot when the sun beams down on it, however, a lot of that heat ends up being prevented from entering the building and saving on energy costs.  Metal roofs are immune to cracks that affect single-ply roofs. However, metal roofs can be vulnerable to leaks around the seams and roof edges. Metal roofs can be customized and formed around angles and protrusions. While they are typically manufactured in large standardized sheets, there are some customization options available to commercial roofing contractors as they prepare to install.

When talking about the installation process and disruptions, keep in mind that some flat roofing materials need more time, space and heavy equipment for their installation. Other materials, such as PVC and TPO, require less installation time and little equipment to install. Some job sites can also become very messy and if you do not require a tear-off with certain roofing systems, then the debris will not be in the way of your business operations.                 

TPO

TPO is a very popular roof type and compared to PVC it is also the best flat roofing material to install. TPO is one of the fastest-growing commercial roofing systems on the market. It is made up of a single layer of synthetic and reinforcing scrim that can be used to cover flat roofs. Not only is TPO roofing material inexpensive, but it also has a decent lifespan between 10 and 20 years. In addition, the white coating that appears on many TPO roofs has all the same energy-saving properties as PVC roofs. They even require less maintenance than EPDM roofs. 

When properly installed and maintained, your commercial single-ply membrane roof can last longer than 20 years. There are a lot of benefits when it comes to single-ply membrane roofing systems. For the fact that single-ply membrane roofing does not include the insulation factor, as a customer, you have more options to choose from to be able to insulate your facility’s roof. The most common TPO material is usually bright white with highly reflective properties. With the bright white roof installation, it is able to reflect UV rays and heat from the building, which end up saving you money during the summer months from decreased energy usage to cool the building interior. Single-Ply Membrane Roofing Systems have been the go-to roofing system for commercial, industrial, and manufacturing facilities for decades.

EPDM

When talking about EPDM rubber roofs compared to the other flat roofing materials, it is one of the most inexpensive roofing materials around. It’s extremely easy to install, therefore you are able to install it yourself or hire a professional roofing contractor. One of the biggest advantages that EPDM rubber roofing has is that it’s very lightweight, therefore, the roof deck doesn’t need any kind of reinforcement. The way that it is installed is by stripping everything right off the roof and applying an adhesive then roll out the roof. There are few seams, which would mean that leaks are fairly rare and an extremely good quality EPDM roof can last you for up to 20 years. This roofing material is fairly durable, it doesn’t scratch or scuff easily, and it can be easily repaired if a leak was to occur. Roofing contractors would use liquid roofing membranes, latex tape or adhesives, and a type of rubber shingle to install over the EPDM roofing in order to repair and patch the leaks. The material may be black and doesn’t absorb heat, it isn’t easy for it to be damaged by UV rays, which in turn helps it hold up well in sunny climates. 

PVC Roofing

PVC roofing is another commercial flat roof material on the market, some building owners usually prefer to use it. However, some roofing contractors usually don’t recommend it as a first option. PVC roofing is one of the most expensive roofing materials compared to other single-ply flat roof materials. However, for the extra expense, PVC roofing offers a good amount of benefits. One benefit would be that the reinforced membrane makes PVC roofs resistant to impact damage and cracking, which in any case would normally shorten the lifespan of single-ply roofs. With a PVC roof, commercial buildings, for instance, manufacturing facilities, wouldn’t face roofing problems that result from chemical exposure because PVC is extremely resistant to chemical damage. PVC roofing requires low maintenance and has a long lifespan, making a very popular material among commercial roofing contractors.  With a PVC roof, it will keep your business building temperature cooler, reducing energy demands. 

Modified Bitumen Roof 

When you compare modified bitumen roofs to other commercial flat roofing materials, modified bitumen stands out as the more low-budget option. Modified bitumen roofs mainly use asphalt membrane as the base to the roof. The surface is vulnerable to cracking and blistering, which greatly reduces their typical lifespan. While this lifespan is less than the more advanced options, the installation savings can still make modified bitumen roofs a serious consideration for some businesses. However, some roofing contractors go back and forth with this option. Modified bitumen roofs are a single-ply membrane system that is most often roll-applied to the surface of your roof. Modified bitumen is quite similar to asphalt roofs, but they have additional polymers in their materials that provide added protection from the elements and help to increase the lifespan of the product. When comparing how popular this roofing material is to the other flat roofing materials, modified bitumen is the least popular flat roofing system. However, it is still pretty common on older roofs. Modified bitumen roofs are installed by rolling out the roofing material after it has been heated with a blow torch. This heating process allows the material to mold itself to the roof surface. However, many roofing contractors try to avoid using this roofing material because installation requires a heated blow torch which ends up being a liability. As well as it requires a lot of maintenance, therefore becoming a hassle.

Metal Roofing Vs Shingles

Metal Roofing Vs Shingles
Metal Roofing Vs Shingles

Where you live is more than just a basic shelter. The roof can be what makes the difference between a house and a safe, secure home. A roofing system should fit the structural design, protect you from the elements, and insulate you from the cold of winter and the summer’s heat. We will discuss the difference between metal roofing systems and asphalt shingles, so you can pick which one would be a better choice for your home.

Varieties

Metal roofing systems come in a variety of styles, largely dependent on the metal used and coatings applied. Aluminum is a metal that needs no coating. Steel, on the other hand, requires specialized treatment to prevent rusting. Other options for your property are zinc, stainless steel, titanium and copper roofing.

Asphalt shingles come in two varieties, the traditional organic ones and the newer fiberglass shingles. The difference is in their layered make-up. There is a 3 core fiberglass covered with an asphalt layer in the fiberglass shingles and the organic shingles have a heavy felt layer under the asphalt.

Roofing Materials - Choose the right look for your property

Appearance

The layered look of asphalt shingles is by far the more popular of the two types. The vast majority of homes in the United States has asphalt shingle roofing, largely because asphalt is the material most builders trust and what homeowners are accustomed to seeing on houses. Asphalt shingles can vary in colors to match the paint or brick of a home, and the variety of their colors is more than with metal roofing. The three-tab shingles give a flat appearance while the more expensive architectural shingles appear more three dimensional.

Metal roofs are rarely seen in urban and suburban areas. The sleek, metallic appearance seems more suited for an agricultural setting. Metal roofing systems are available in a variety of colors and styles to match the rest of the home. The metal can be in panels, tiles, or shingles, but the appearance of a metal roof still can be jarring in a neighborhood full of asphalt shingle roofs.

Installation

Metal roofing installations are much harder than installing a shingle roof, but due to the weight of shingles, especially the traditional ones, the previous shingle materials may need to be removed first. Also, warranty and insurance requirements may demand the removal of previous asphalt shingles. A roofing square of three-tab shingles, which is 100 square feet, can weigh 200 pounds, and a square of architectural shingles can weigh up to 500 pounds. Because the installation is easier, even with removing a previous roof, installing asphalt shingles can take as little as a day or two of labor, depending on the size of the house.

Metal roofing, on the other hand, is much lighter and can be installed directly over the previous roof. The weight varies by the material used. Aluminum weighs only about 50 pounds per square while steel weighs 100 to 250 pounds. One reason why roofing with metal takes longer is the extra step of laying plywood 4 or oriented strand board (OSB) under the metal. This additional step eliminates the added noise of metal. With proper installation, rain or even hail should sound no different inside a home with a metal roof than it does inside a home with an asphalt shingle roof.

Both of these jobs are best left to professional Albany roofing contractors. Working on a roof can be dangerous, and installing roofing materials is a very precise and demanding job. Areas around vents must be properly sealed, and flashing must be carefully put into place. Also, some warranties may be voided if the materials are not installed by a professional Albany area roofing contractor.

Costs

A metal roofing will cost approximately $265 to $600 per roofing square or $2 to $6 per square foot for steel or aluminum shingles, $120 to $150 for corrugated steel panels, and $700 to $900 for copper or zinc. After adding installation, a steel or aluminum roof will cost about $500 to $1,000 per square. For a home with a 1,500-square-foot roof, this comes to about $7,500 to $15,000. For a home with a 2,500-square-foot roof, this comes to $12,500 to $25,000. This is, on average, about three times the cost of asphalt shingles and is another reason many homeowners opt for an asphalt shingle roof instead.

Energy Efficiency

Asphalt shingle roofing is much less expensive at about $60 to $90 per roofing square for three-tab asphalt shingles or $100 to $120 per square for architectural shingles. Felt is installed under the shingles at $40 per roll of synthetic underlayment, at $85 per 400 square feet. Installation costs about $80 to $200 per square, and removal of a previous roof shingles adds about $80 to $150 per square. If architectural shingles are used, the labor rises to $200 to $400 per square. A highly pitched or steep roof will add even more to the installation cost. For a property with a 1,500-square-foot roof, the cost of a three-tab shingle roof comes to about $2,100 to $4,800 without the removal of the previous shingles, an additional $1,200 to $2,250. For properties with a 2,500-square-foot roof, the cost comes to between $3,500 and $8,000 without the removal of the previous shingles, an additional $2,000 to $3,750. These prices make asphalt shingle roofing an almost certain choice for first-time home buyers and contract builders. Newer fiberglass varieties can be even less expensive.


A metal roof will lower your energy bills by about 40 percent in the summer. The reflective surface lessens the transfer of heat into the home. On the other hand, asphalt shingles absorb the sun’s heat, transferring it through the roof to the home, making the home’s cooling system work harder. This is why asphalt shingles are recommended more strongly for temperate climates.

In winter, asphalt shingles perform better, using the heat absorbed from the winter sunlight to make the home much warmer. However, metal roofs also perform well in winter. The year-round energy usage will still be lower with metal than with asphalt.

Even so, some asphalt shingle styles are designated as cool roofs and join some metal roofs in carrying an Energy Star rating for higher energy efficiency. These roofing materials are certified to reflect more of the sun’s energy, lowering the roof’s temperature by up to 50 degrees Fahrenheit. Even though other factors can affect the amount of savings offered, they can decrease demand on the home’s cooling systems at peak times by 10 to 15 percent.

To offset the cost of installing a new roof, you can look for Energy Star certified asphalt shingles or metal roofs. When using these energy-efficient materials, 10 percent of the materials cost, up to $500, can be received as an energy credit.

Durability

The higher cost of metal roofing is also offset by its long-life expectancy. A metal roof can last for 60 years or more with little maintenance. Most roofing manufacturers offer a 50-year warranty on metal roofs. However, an asphalt roof will need to be replaced two or three times during that same 60-year period. Warranties for asphalt shingle roofs vary from 20 to 25 years.

Asphalt shingles are susceptible to hail and high wind damage, although fiberglass shingles are more durable than organic ones. Also, if asphalt shingles do not get adequate sunlight, they can accumulate mold, algae, or mildew. Metal roofs, on the other hand, are superior performers in high winds and bad weather, and they are impervious to molds, mildews, and bugs.

Metal roofs perform so well under harsh conditions that homeowners in over 25 states are eligible for insurance discounts when they install impact- and fire-resistant metal roofs.

If the metal roof is a low-quality steel without an adequate rust-resistant coating, then use near salt water is not advised. More expensive, rust-resistant metal alloys and coatings should be used instead.

Fire Resistance

Some manufacturers’ asphalt shingle lines are rated Class A for fire safety, especially the fiberglass varieties. Also, all metal roofs are fire resistant, steel and copper more so than aluminum. This makes metal roofing a good choice in areas prone to wildfires.

Recyclability

Metal roofing systems win the day regarding recycling issues. Some are made with recycled materials, and all are completely recyclable. About 1 million tons of asphalt shingles are disposed of each year, and they can be recycled into a variety of products. The cost to recycle them is generally less than to place them in landfills. However, available recyclers for asphalt shingles are few, but the development of more recycling availability is underway.

Maintenance

Repairs are more difficult with metal roofing since most of the metal used is made in sheets and must be replaced that way. When damage occurs to a roof, asphalt is easier and less expensive to repair or replace. Metal roofs require little maintenance and need to be repaired far less frequently.

Resale Value

Because a metal roof is strong, durable, and energy efficient, it should increase a home’s resale value. By some estimations, the resale value will increase by 1 to 6 percent over a house with asphalt shingles. The buyer must appreciate the look of a metal roof, however. Any new roof will help sell a home since buyers want to feel secure about the condition of the roof over their heads.
