Do you have to make a decision soon about a new commercial roof? Let’s take some time to discuss TPO vs PVC commercial roofing membranes. We’ll discuss the benefits of these single-ply roofing systems and the differences between the two types. We’ll also give you a general idea of the costs of each of these popular roof systems.

Benefits of TPO and PVC Roofing Systems

Both TPO and PVC are single-ply membranes made for low slope and flat roofs.

TPO (Thermoplastic Polyolefin) and PVC (Polyvinyl Chloride) are flexible membranes that conform to the shape and movement of the roof of your commercial building. Besides being flexible, both PVC roofs and TPO roofs are resistant to chemicals, grease, and oil – with PVC offering more chemical resistance.

Additionally, TPO and PVC membranes are light-colored, which makes them more resistant to UV radiation. This means that both the TPO and PVC membranes are environmentally friendly, allowing you to reduce your energy usage during the summer.

TPO and PVC are also lightweight and odorless. In addition, they feature watertight heat-welded seams and can be installed in several ways (mechanically fastened, fully adhered, and self-adhered.)

Differences Between TPO and PVC Roofing Materials

PVC is the older material. It has been used on commercial roofs since the 1960s. TPO was designed decades later from a combination of PVC and another rubber membrane called EPDM (Ethylene Propylene Diene Monomer.)

Even though TPO was formed later, there are benefits to the older PVC membrane, as PVC offers excellent fire resistance and is generally less expensive. However, TPO is a stronger roofing material with a higher tear and break strength.
