What is TPO Roofing?

TPO-based products have been used in various applications, including the automobile industry since the 1980s, and have seen their usage continue to expand.

Since that time, the TPO single-ply roofing market has grown to hundreds of millions of square feet annually with TPO membrane comprising the fastest growing segment of the U.S. single-ply roofing industry.
