TPO Versus EPDM: Which Material Is Right For Your Flat Roof

TPO Versus EPDM: Which Material Is Right For Your Flat Roof

Flat roofing systems are the most common among commercial buildings. When it comes time to replace your flat roof system, you will have a lot of options. Two of the most popular options are TPO and EPDM. Both materials utilize newer polymer technology, and offer durability and long term protection for your commercial property. If you are considering these materials, here is a comparison to help you decide which of the two is best for your commercial roof.


What Is Thermoplastic Polyolefin (TPO) Roofing?


TPO is a type of single-ply roofing made of advanced polymers of thermoplastic and a filler like fiberglass, talc, or carbon fiber. TPO is extremely popular because it reflects the UV rays, which help insulate the building. This is not only environmentally-friendly, it can save building owners thousands on utility costs. TPO is installed in large sheets with the seams sealed. So installation goes quickly, which makes TPO roofing more affordable than some other options. TPO also lasts up to 30 years and is both fire and chemical resistant. Finally, TPO comes in a range of color options so property owners can get the look they want for their building.


What Is Ethylene Propylene Diene Terpolymer (EPDM) Roofing?


EPDM is a type of synthetic rubber that gets its name from the ingredients of the polymer. Like TPO, EPDM has a lifespan of about 30 years if properly maintained. It is extremely lightweight but is very durable with a high resistance to UV rays, hail, and extreme temperature shifts. EPDM comes in less color options than TPO and is only offered in black and white. EPDM is a green roof option as well because it offers insulation that reduces the costs of utilities. Like TPO, it also has a fast installation process, so it also is very affordable.


Which Is Right For My Roof?


TPO and EPDM have a lot in common, they are both long lasting, eco-friendly, single ply roofing materials. However, there are important differences between the two materials. First is the cost. TPO is often more expensive than EPDM. Secondly, the installation is different. TPO tends to be chemically adhered, while EPDM is mechanically fastened to the roof deck. These subtle differences make a big impact depending on the unique needs of your building.
