What Is The Difference Between EPDM And PVC Roofing?

What Is The Difference Between EPDM And PVC Roofing?

The main difference between EPDM and PVC roofing is that they are made of different materials. Simply put, EPDM is a synthetic rubber material, while PVC is a thermoplastic. 

Although they have some similarities in terms of durability and weather resistance, PVC is oil resistant and EPDM has subpar oil resistance. On the other hand, EPDM tends to have better water absorption resistance than PVC does. Additionally, compared to the lifespan of other commercial roofing materials EPDM can last much longer than PVC with a lifespan of up to 50 years for EPDM compared to 20-30 years for PVC roofing systems. Lastly, EPDM and PVC handle temperature differently, which is another aspect to consider when looking at commercial roofing systems. For example, EPDM does better in extreme cold temperatures, whereas PVC can become brittle when exposed to frigid temperatures and can even crack or break if walked on during its exposure.

EPDM vs PVC Cost

When looking at different roofing materials, it is important to look at your budget to determine which roofing system will work best for you. And, of course, EPDM and PVC vary in price. EPDM is cheaper than PVC on average, coming out to $4.50 to $5.50 per square foot, whereas PVC can cost up to $12 per square foot (although the range is somewhere between $4 to $7 or up to $8 to $12 per square foot).
