Types of Commercial Roofs


Types of Commercial roofsThe typical roof in America is designed to last around 30 years. While many roofs tend to last homeowners longer than that, some roofs may need replacing or repairing in a much shorter time for a number of reasons. One thing that is always true is that if your roof needs replacement, you do not have the option to avoid it, especially when it comes to commercial roofs. 

Commercial roofs do much more than protect your staff and clients from the outside elements. They are an essential aspect of your business establishment’s appearance and demonstrate the professionalism of your business. On the market, there are many different types of commercial roof options. CertainTeed will dive right into six of these types of commercial roofs to help you make an informed decision when it comes to your next roofing project.

Shingle Roofing

Shingle roofs tend to be the most popular for residential roofs, but the material is also commonly used for steep-slope commercial roofs. These shingles are made from a variety of materials, but the two most common types of shingles are asphalt and architectural.

Asphalt shingles are the most commonly used type of shingles, and they are known for their affordability. On the other hand, architectural shingles are multilayered and heavier, as well as more aesthetically pleasing.

Single-Ply Roofing

A Single-Ply Roofing System typically is made up of either PVC, TPO, or EPDM. These materials generally are prevalent amongst consumers due to their flexibility and strength. These materials resist cracking, peeling, and many other forms of weathering. Single-Ply Roofs are installed in one single layer, hence the system's name.

Now, we will take a closer look at these three different materials found in Single-Ply Roofs.   

  •  PVC

Also known as polyvinyl chloride, PVC roofs are made up of two PVC layers with polyester reinforcement. The top layer of these roofs contains specific additives to make the roof resistant to UV radiation, and the bottom layer has plasticizers for added flexibility, making installation easier.

The durability and longevity of these PVC roofs make them one of the best and most preferred commercial roofing systems on the market. A bonus is that PVC is highly recyclable, making the roof very eco-friendly.

  • TPO

Thermoplastic polyolefin is a very popular roofing material in terms of low-slope roofs. These roofs contain reinforced sheets that feature heat-welded seams and tend to be very reflective. 

  • EPDM

Finally, EPDM or ethylene propylene diene monomer roofs are known for their toughness and elasticity. These types of commercial roofs are great for resisting UV lights and are very affordable.

Metal Roof

Commercial metal roofs are one of the oldest options on the market. Typically, galvanized steel is used for these roofs, but tin and aluminum are also sometimes used. Metal roofs are typically very light in weight, making it easy for contractors to install a new roof over an existing roof. Additionally, a coating can be added to protect the roof from rust and UV radiation.

Metal roofs tend to be very cost-effective, and there are a wide variety of designs and colors. Additionally, metal roofs are very stable and can withstand extreme weather conditions.

Built-Up Roofing System

Built-up roofing systems are the oldest roofing option on the market. These systems consist of 3 to 5 layers that provide added protection for your roof and withstand the most extreme weather conditions.

Modified Bitumen Roofing System

Combining both asphalt and a chemical polymer, modified bitumen roofing systems tend to be very flexible and temperature resistant. These roofs are applied in multiple layers in a variety of ways. These systems are highly rated for withstanding fire, wind, and weather.

Liquid Applied Roofing

These unique commercial roofing systems have a membrane constricted in place using polyester and resin, providing excellent waterproofing qualities. These roofing systems can be installed by a roller or sprayed on in separate coats.
