Flat Roof Lifespan: How Long Does Each Material Last?
The lifespan of your flat roof depends on the type of material, installation quality, and regular maintenance. Let’s explore how long each option typically lasts.
TPO Flat Roofs
Thermoplastic Polyolefin (TPO) is a popular choice for commercial properties. A well-installed TPO roof can last 20–30 years with proper care.
EPDM Flat Roofs
Ethylene Propylene Diene Monomer (EPDM), also known as rubber roofing, is valued for its durability. With minimal maintenance, EPDM roofs can last 25–35 years.
Modified Bitumen
Modified bitumen roofs are reinforced with fiberglass or polyester, making them strong against foot traffic. Their average lifespan ranges from 15–25 years.
Factors That Affect Lifespan
Quality of installation
Local climate and weather conditions
Frequency of inspections and maintenance
