EPDM Roofing FAQs

Common questions about commercial EPDM roofing systems.

How long does EPDM roofing last?

EPDM has a proven track record of 30-50+ years when properly installed and maintained. Many original EPDM installations from the 1970s are still performing today.

Is EPDM suitable for Calgary's climate?

Yes—EPDM remains flexible down to -40°F and handles extreme temperature swings well. It's an excellent choice for Alberta's harsh winters and summer heat.

Can EPDM be repaired if damaged?

EPDM is one of the easiest membranes to repair. Patches can be applied using adhesive or tape, making repairs quick and cost-effective.

What's the difference between black and white EPDM?

Black EPDM is the traditional option with proven longevity. White EPDM offers reflective properties for energy savings but requires more maintenance to keep its reflective coating intact.
