Closely related to TPO roofing, PVC roofs are another popular single-ply membrane material. While both are thermoplastics with similar qualities, they differ slightly in a few aspects, including:\
Per square foot, TPO is cheaper than PVC with both materials requiring similar installation times. However, at times, TPO can be slightly more labor intensive to install.
Depending on whether you select glued or welded seams for your TPO installation, it may require slightly more work than a PVC roof.
Both TPO and PVC have natural reflective characteristics, which significantly increase the energy efficiency of your building during hot summers. The smoother the surface, the better the reflectivity characteristics because it’s more difficult for dirt and debris to build up over time.
Longevity and Durability
Since TPO roofing membranes lack plasticizers, they generally last slightly longer than PVC roofing systems. They tend to weather better and stand up against long-term heat exposure. However, PVC roofs offer better chemical resistance.
