How long does a Firestone EPDM roof last?
How long does a Firestone EPDM roof last?
50 years
Studies show a life expectancy for EPDM membranes of more than 50 years, even when exposed to sunlight. On top of its exceptional service-life, the membrane is easy to repair, even several decades after its installation. Its lifespan can thus be extended to even more than 50 years.
What is a ballasted roof system?
A ballasted roof means that the roof membrane is not anchored or adhered in any way to the decking material. It is, however, ballasted, generally with gravel.
How do you maintain EPDM roofing?

How much does roof ballast weight?

Why do roofs require ballast?
The ballast is used to keep the roofing system cool and of out of the sun’s harmful rays, thus keeping energy costs down. The gravel top coat is also extremely resilient to heavy foot traffic and high-wind scenarios.
Can you repair EPDM?
Repairing Punctures in or Damage to the EPDM Membrane However, one of the main advantages to EPDM is that it can be very easily repaired using a patch. There are also puncture-resistant single-ply membranes available (such as RESITRIX®).
When should I replace my EPDM roof?
