TPO Flat Roof

TPO (Thermoplastic Polyolefin) is a single-ply membrane roofing system designed for flat and
low-slope roofs.

The membrane is heat-welded at the seams, creating a continuous watertight surface.

TPO reflects sunlight and heat, helping keep buildings cooler in summer while protecting against rain, snow, and standing water — making it ideal for Ontario weather conditions.

How TPO roofing works
Large membrane sheets are rolled out across the roof deck and mechanically fastened or adhered to the surface.

Seams are heat-welded together, forming a sealed barrier that prevents water infiltration.

Because there are no overlapping shingles or exposed fasteners, water cannot penetrate the roof surface.

The flexible membrane also expands and contracts with temperature changes without cracking.
