Depending on the material, a properly installed flat roof can last 15 to 30 years. EPDM and TPO systems typically last 20-25 years with regular maintenance.
The best material depends on your property, budget, and needs. EPDM is durable and affordable, TPO offers energy efficiency, and modified bitumen provides superior waterproofing. We help you choose the right option.
We recommend inspecting flat roofs at least twice a year — in spring and fall — and after any major storm. Regular inspections help catch issues early and prevent costly repairs.
