The Pros and Cons of Different Roofing Materials

September 1, 2020 by Infinite Roofing Leave a Comment

Whether your current roof is in rough shape or you are interested in an upgrade, an important part of the replacement process is determining which material to go with. There are many different roofing materials to choose from, but step one is to find the best roofing company in your area. A qualified roofing contractor will help you find the best roofing material for your home and provide an estimate. Before meeting with your local contractor it is best to do your own research so you know which questions to ask. If you are curious about the pros and cons of each roofing material, this will be a great guide for you!

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.

Pros

Shingles are the most affordable roofing material option that is available and the installation process is not complicated. Very little maintenance is required throughout the life of your shingled roof and its lifespan is around 25 years. 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.

Commercial Flat Roofing

November 18, 2019 by Infinite Roofing 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.
