The difference between EPDM and TPO roofing is that EPDM is a rubber material, while TPO is a plastic blend. Both are single-ply roofing systems used on flat or low-slope roofs. EPDM lasts 20 to 30 years, while TPO typically lasts 15 to 20 years. TPO costs less upfront, but EPDM is often more durable. According to industry data, 91% of commercial roofers use single-ply roofing systems like TPO, EPDM, and PVC.

What Is Epdm Roofing?

EPDM stands for ethylene propylene diene monomer. It is a rubber roofing material that has been used for over 50 years. EPDM comes in large sheets and is often glued or mechanically attached to the roof deck.

EPDM resists UV rays and extreme weather well. It also stays flexible in cold temperatures. This makes it a good choice for northern climates.

What Is Tpo Roofing?

TPO stands for thermoplastic polyolefin. It is a newer plastic roofing material made from rubber, plastics, and other compounds. TPO sheets are heat-welded together to create a seamless roof.

TPO is lighter than EPDM and reflects more sunlight. This helps cool your building in hot weather. TPO is easier to install than EPDM, which lowers labor costs.

Which Should You Choose?

Choose EPDM if you live in a cold climate or want a longer-lasting roof. EPDM performs better in freezing temperatures and resists punctures well.

Choose TPO if you want lower upfront costs and better heat reflection. TPO is ideal for hot climates where energy savings matter. According to industry data, 38% of commercial roofers use TPO systems. In comparison, 30% use EPDM, and 18% use PVC. Both materials are solid choices. Your climate, budget, and roof shape should guide your decision.
