The average life of a flat roof depends on several factors, including the type of roofing material, the quality of installation, the climate, and the level of maintenance. Here are some estimates for the average lifespan of common flat roofing materials:
- Built-up roofing (BUR): 15-30 years
- Modified bitumen roofing: 10-20 years
- EPDM roofing: 20-30 years
- TPO roofing: 15-25 years
- PVC roofing: 20-30 years
It’s important to note that these are just estimates, and the actual lifespan of a flat roof can vary based on the specific conditions of each installation. Regular inspections and maintenance can help extend the life of a flat roof by identifying and addressing potential issues before they become major problems.
