Single-ply roofing membrane that chemically bonds rubber, ethylene, and propylene—as well as numerous filler materials—TPO roofs have been vastly growing in popularity ever since their introduction in the early 1990s.
Part of what is fueling TPO's recent rise is its energy-efficiency, as these types of commercial roofs are more readily available in white and light gray (as well as in black) compared to their closest competitors: PVC and EPDM. TPO is said to offer the best of both EPDM and PVC in one package. The material is closer to a rubber roof in cost, but it also features welded seams for durability—like PVC membranes.
PVC Single-Ply Membrane
PVC membranes are a single layer of thermoplastic material. PVC roofs are especially strong and durable, featuring a minimum breaking point of 300 pounds per inch, compared to the industry-recommended 200 PPI.
Seams are heat-welded (i.e. hot air welded) to form a watertight bond. The welded seams are actually stronger than the material itself. Most PVC membranes, especially while-colored ones, provide energy efficiency, as they reflect the sun’s energy instead of absorbing it. The PVC membranes often come with lifetime warranties.
Commonly known in the industry as a rubber roofing system, EPDM's biggest advantage over a PVC roof membrane is its lower cost. PVC and EPDM typically go 1-2 in terms of popularity for commercial flat roofing, depending on what area you live in.
The seams of EPDM are not as strong as the PVC, however. EPDM also tends to absorb heat, which can drive up utility bills for the property owner.
