TPO and PVC are single-ply membranes designed to be used on low slope and flat roofs for either residential or commercial buildings. There are specific differences between TPO and PVC worth knowing when deciding which one to choose for your commercial roof.

TPO stands for Thermoplastic Polyolefin and PVC stands for Polyvinyl Chloride. TPO was designed to be an improved version of both PVC and another rubber membrane called EPDM or Ethylene Propylene Diene Monomer. TPO combines the benefits of PVC and EPDM, offering more flexibility and reflectivity, as well as being increasingly environmentally friendly and more weather-resistant.

The Similarities of TPO vs. PVC Roofing

Both thermoplastic materials are heat-weldable, making them more resistant to leaks. Both have fewer seams when installed properly, giving them fewer penetrable areas for potential leaks. Both are white in color, offering a reflective surface on the roof and making them more resistant to heat and the sun’s UV rays. This reflective, cool surface is energy efficient by helping to reduce AC usage during the summer months. Both materials are resistant to chemicals, grease, and oil, but PVC holds up better under exposure. Both are designed with flexibility, conforming to the shape and movement of your roof.

Benefits of TPO

TPO is less expensive than PVC, has superior weathering, and is slightly better at being tear and break resistant than PVC. TPO also utilizes materials that are designed to not break down over time, creating greater long-term durability over PVC.

Benefits of PVC

PVC, though slightly more expensive, does not absorb or get weakened by chemicals, oils, and grease, making it the best choice for restaurants and other buildings that have grease traps or risk of exposure to chemicals and oils. PVC is slightly more flexible than TPO, which is helpful during the installation process. PVC roofs hold up better than TPO roofs in intense heat and sun exposure.

Deciding between TPO and PVC can be a challenge, but having a trusted, knowledgeable commercial roofing contractor that understands your buildings’ needs is important, as they can guide you in making the right choice for your building.
