What is TPO?
Roofing Glossary · Materials
Definition
Thermoplastic Polyolefin — a single-ply white or light-colored roofing membrane widely used on low-slope and flat roofs. TPO is heat-welded at seams to create a monolithic waterproof surface, and its reflective white surface qualifies for Energy Star and cool roof designations, reducing cooling loads. It offers a balance of material cost, installation ease, and long-term performance for commercial and residential flat roof applications.
