Overview
Thermoplastic Polyolefin (TPO) is the most widely installed single-ply commercial roofing membrane in North America. Its white or light-gray surface reflects solar energy, reducing cooling loads year-round. Heat-welded seams form bonds stronger than the membrane itself, eliminating adhesive failure as a leak path. Evangel installs TPO across all major commercial substrates — concrete deck, steel deck, and wood — using mechanically fastened, adhered, and induction-welded attachment methods.
