PVC Roofing vs TPO Roofing Systems

Class A Roofing Consultants works extensively with Duro-Last® PVC roofing materials for low-sloped and flat roofs for commercial buildings in the Oregon and Northern California areas. The PVC roofing membrane is prefabricated off-site with stronger seams and measured to fit precisely for your roof.

Difference between PVC vs TPO

TPO is a type of single-ply roofing membrane and one of the most widely used roofing materials in the industry. It's made from a single layer of synthetics for commercial and industrial flat roofs and cost-efficient, making it a popular type of roofing material. However, there are some major durability and longevity concerns with TPO roof installation. The TPO roofing system can help keep buildings cooler, but it can also bring serious problems when the heat becomes too high. Additionally, TPO uses seams that offer similar durability to PVC, but has the tendency to shrink over time causing gaps at curves for potential leaks.

PVC Roofing Alternative for TPO Roofing

PVC is a great alternative to TPO for its high durability and longevity. Although PVC is typically known for being more expensive, this material requires less installation time reducing labor costs and less interruption to business.
