There is a plethora of roofing structures for commercial buildings other than built-up roofing. But learning what other options have to offer allows a more educated decision-making process. Single-ply roofing is the opposite of built-up roofing. Single-ply membranes are sheets of rubber, or plastic and other synthetic materials. The three main types of single-ply membrane are ethylene propylene diene monomer (EPDM), thermoplastic polyolefin (TPO), and polyvinyl chloride (PVC).
All of these single-ply roofing options are durable, cool roof systems, which means they’re UV resistant and energy efficient. Single-ply membranes are long-lasting, each with an average 25- to 40-year lifespan. Certified roofing contractors recommend these options for commercial buildings due to their proven track record and longevity. Years after they’ve been installed, single-ply membranes can be repaired or rewelded.
