PVC, short for polyvinyl chloride, is made of thick, flexible thermoplastic material that, like TPO, is highly resistant to damage, versatile, and durable. PVC can be made to fit a flat roof shape and is incredibly easy to install. Although it does share some similarities with TPO it isn’t used as widely in areas that are susceptible to intense weather conditions, such as torrential rain, snow, or ice.
The lifespan of a PVC roofing system often depends on the weather conditions, as well as the quality of work by a contractor during installation. It is suggested that all PVC roofing systems be inspected twice a year.
PVC Roofing vs tpo roofing systems
As opposed to thermosets, which require the use of adhesives, the seams on thermoplastic single-ply membranes can be hot-air welded together to form cohesive laps. When thermoplastic membranes cool, they return to their original material type.
PVC and TPO are two of the most commonly installed thermoplastic single-ply membranes. According to SPRI, “Most thermoplastic membranes are manufactured to include a reinforcement layer, usually polyester or fiberglass, which provides increased strength and dimensional stability.”
Since these membranes are characteristically light in color, they provide excellent reflectivity, resulting in potential energy savings. PVC membranes are manufactured from a combination of PVC resin, stabilizers, pigments, fillers, plasticizers, biocides, and various processing aids. Unlike TPO membranes, which require additives to increase fire resistance, PVC membranes are natural fire retardants.
While problems with PVC membranes back in the 1960s may have colored some facilities professionals’ views on these thermoplastic roofs, the use of chemical plasticizers that evaporated (causing embrittlement and shrinkage) have long since been discontinued.
The other popular thermoplastic membrane on the market today is TPO. “TPO polymers are blends or alloys of polypropylene plastic or polypropylene and ethylene propylene rubber (EPR) or ethylene propylene diene terpolymer rubber (EPDM),” SPRI reports.

TPO can be installed in a multitude of ways. Plus, with the introduction of peel-and-stick products, installation time can be reduced significantly. Like PVC, TPO remains hot-air weldable throughout its service life, simplifying repairs and maintenance. This makes it a popular choice for homeowners, PVC roofing companies, and contractors alike.
