What is the Life Expectancy of a Commercial Roof?
When considering the lifespan of commercial roof systems, the answer isn’t as simple as it might seem. Numerous factors influence how long a roof will last, from the materials used to the quality of installation and ongoing maintenance. To help you better understand what affects a roof’s longevity, we’ve compiled key insights to guide your decision-making process.
Factors That Determine the Lifespan of Commercial Roof Systems
Several factors influence the durability and lifespan of a commercial roofing system. Understanding these can help building owners and facility managers make informed decisions about their roofing needs.
Lifespan by Type of Roofing Materials
The type of roofing material used plays a significant role in determining how long a commercial roof will last. Here’s an overview of the most common commercial roofing systems and their average lifespans:
- EPDM (Ethylene Propylene Diene Monomer)
Known for its durability and flexibility, EPDM roofing is made from industrial-grade synthetic rubber that expands and contracts with temperature changes. A properly installed EPDM roof can last over 30 years. - Modified Bitumen Roofing
This modern version of the built-up roofing system (BUR) uses multi-ply roofing materials. With proper installation, modified bitumen roofs typically last between 10 and 20 years. - Metal Roofing
Metal roofing is one of the oldest commercial roofing systems. When installed correctly and with adequate slope, metal roofs can last 30 years or more. - TPO (Thermoplastic Polyolefin) Roofing
TPO roofing consists of heat-weldable sheets made from a blend of polypropylene and ethylene propylene rubber components. These roofs are flexible in cold weather and can last 20–30 years with proper maintenance. - PVC (Polyvinyl Chloride) Roofing
PVC roofing membranes are available in various colors, thicknesses, and reinforcements, making them a versatile choice. The average life expectancy of a PVC roof is up to 30 years.
Maintenance: The Key to Longevity
One of the most critical factors in extending the life of a commercial roof is regular maintenance. Studies from the National Roofing Contractors Association (NRCA) and the American Institute of Plant Engineers (AIPE) have shown that routine maintenance can increase a roof’s lifespan by 30% to 100%.
In addition to prolonging the roof’s life, a proper maintenance program:
- Ensures compliance with manufacturer warranty requirements.
- Reduces the risk of injuries or accidents.
- Protects businesses from costly shutdowns and equipment damage.
Regular inspections and prompt repairs are vital to keeping your roof in top condition.
