The lifespan of a commercial building roof can range from 20 to 40 years, depending on the materials used and the quality of maintenance.

The lifespan of common commercial roofing materials…

1. Metal Roofing – Metal roofs are known for their durability and longevity, with lifespans ranging from 40 to 70 years or more with proper maintenance. Factors such as the type of metal used (e.g., steel, aluminum, copper), coating applied, and exposure to harsh weather conditions can influence the lifespan of a metal roof.
2. Single-Ply Membranes – Single-ply roofing membranes, such as EPDM, TPO, and PVC, typically have lifespans ranging from 20 to 30 years. Proper installation, regular maintenance, and protection from UV radiation and environmental factors can help extend the lifespan of these roofing systems.
3. Built-Up Roofing (BUR) – Built-up roofing systems, also known as tar and gravel roofs, have lifespans ranging from 20 to 30 years or more with proper maintenance. The number of layers, quality of materials, and protection from water ponding and UV radiation can affect the longevity of BUR roofs.
4. Modified Bitumen Roofing – Modified bitumen roofing systems typically have lifespans of 20 to 30 years. Proper installation, regular inspections, and timely repairs can help maximize the lifespan of modified bitumen roofs.
