How Long Does a Flat Roof Last?
Mineral felt: 15–20 years. EPDM: 30+ years. GRP: 25+ years. Liquid systems: 20–25 years. Single-ply: 25–30 years. All assume manufacturer-trained install — the detailing is what fails first, not the membrane.
Why this matters
Most roof failures we attend could have been avoided by acting on the warning signs six months earlier. The cost of acting early is usually 10–20% of the cost of acting after the leak.
