Flat roofing comes in a number of forms, and two of the most popular options for commercial establishments are thermoplastic polyolefin (TPO) and ethylene propylene diene terpolymer (EPDM) single-ply roofing. Both are great in their own right, and understanding their individual advantages will help you in choosing the best option for your property.
TPO is a roofing membrane that can be repeatedly softened or hardened when heating or cooling is applied. They are commonly white in color, making them a cool roofing option as they effectively bounce back heat from the sun and limit passive heating through the roof. TPO roofing also offers high resistance to punctures, which is ideal for anyone keen on avoiding a leaking roof.
EPDM roofing systems, on the other hand, are thermoset membranes, meaning they retain their form once they are “cured” after installation. Colloquially known as rubber roofing, EPDM roofs offer great protection against hailstorms, with hail bouncing off their rubberized surfaces without trouble.
What to Choose?
At the end of the day, it depends on what your needs are. Both are durable, for instance, but if you are in an area that sees a lot of hail, then EPDM is the better choice for you. However, if you are more concerned about puncture-like damage, you can’t go wrong with TPO. The best way to decide is to consult with a skylight and roofing expert. With a good understanding of your needs, they are in the best position to recommend the right flat roofing option for you.
