TPO (thermoplastic olefin) is a single ply roofing membrane that is energy efficient and has the benefits of EPDM roofing and PVC roofing, but without the drawbacks and extra costs. TPO roofing is as UV-resistant and as heat-resistant as EPDM roofing, and as heat-weldable as PVC roofing.

TPO roofing is an economical and efficient roofing alternative to PVC roofing products. TPO is a single-ply roofing system consisting of a thermoplastic polyolefin membrane. This membrane is composed of three layers: a TPO polymer base, a polyester-reinforced fabric center (scrim), and a thermoplastic polyolefin compounded top ply.

TPO Roofing is economical and fits different roofing styles. One of the factors that makes TPO roofing attractive both in residential and commercial construction is its reasonable cost. TPO offers many of the same benefits as PVC roofing, such as hot-air weldable seams and energy efficiency, but at a lower cost.
