TPO Roofing vs EPDM
EPDM roofing is made from ethylene propylene diene monomer (or a kind of rubber.) Its primary advantage over TPO roofing is simply that it’s cheaper. Otherwise, EPDM roofing has worse performance and weaker seam strength, meaning there is a greater risk of water intrusion where the sections of roofing connect.
Though more expensive, we recommend TPO roofing over EPDM roofing simply because it offers better rain protection and better performance. You’ll get a longer lifespan from TPO, which helps to offset its higher cost. Plus, TPO is simpler to repair than EPDM. With TPO roofing, a repair job is as simple as cutting out and replacing the damaged sections.
We can install TPO roofing as peel-and-stick or with heat application, whichever best suits your roof.
When to Choose EPDM
While TPO is a better choice for most roof, there are a few circumstances where we may recommend EPDM roofing. For example, if you’re reroofing an exceptionally large roof, you may need to choose EPDM to stay under your budget.
Or, if you’re close enough to the coast that your roof will be exposed to salt and cold winds, EPDM may be a better choice to withstand these stressors than TPO. That being said, Metacrylic is an even better choice if your roof is exposed to coastal conditions.
What About Metacrylic?
While Metacrylic is neither TPO roofing or EPDM, it is among our two top choices for flat roofing in California. Metacrylic handles our climate perfectly, as it is resistant to high temperatures, earthquakes, salt spray and high winds. While Metacrylic is a newer roofing material, it offers superior weather protection for roofs in California. In fact, it is so durable that it is also used as ground cover, even under high traffic.
