TPO Roofing

TPO Roofing in Norman, OK

TPO — thermoplastic polyolefin — has become one of the most popular commercial roofing systems in the United States, and for good reason. It's a single-ply membrane rolled out across a flat or low-slope roof and either mechanically attached or fully adhered, with the seams between sheets heat-welded together to form one continuous, watertight surface. The membrane is reinforced with a polyester scrim that gives it real strength and resistance to tears and punctures. Norman Roofing Co. installs, repairs, and maintains TPO roofs across Norman and the OKC metro — and we back our flat-roof work with our promise: it won't leak — guaranteed.

We install quality TPO systems, including GAF EverGuard TPO, so you get a proven membrane with strong manufacturer backing on commercial buildings throughout the metro.

Why TPO Works Well in Oklahoma

• Energy-efficient & reflective. TPO's typically white, light-colored surface reflects solar heat (a true "cool roof"), helping lower cooling costs through brutal Oklahoma summers.
• Strong, welded seams. Heat-welded seams fuse the sheets into one membrane — far more leak-resistant than glued or taped seams.
• Durable. Polyester reinforcement resists tears, punctures, and dirt buildup; the membrane also stays flexible as the building moves.
• Fast, efficient installation. Wide sheets and straightforward attachment keep labor time and cost down on large roofs.
• Resistant to the elements. Holds up to UV, heat, and weather exposure year after year.

How TPO Is Installed

Deck Prep & Insulation

We prepare the deck, address any wet or damaged areas, and install the appropriate insulation board to set up a flat, sound base and good thermal performance.

Membrane & Welded Seams

The TPO sheets are rolled out and secured, then the overlapping seams are heat-welded with hot-air equipment so the membrane becomes one continuous, monolithic surface. Clean welds are the difference between a roof that lasts and one that leaks — and it's where our experience shows.

Flashings & Details

We finish the perimeter, curbs, drains, and penetrations with proper flashings, because on a flat roof the details are where leaks start. Done right, a TPO roof delivers years of dependable, low-maintenance protection.

Residential vs. Commercial Use

TPO is primarily a commercial and industrial system, ideal for the large flat and low-slope roofs on offices, warehouses, retail, and apartment buildings — a core part of our commercial roofing work. It also suits residential flat or low-slope sections. If you're comparing flat-roof options, it's worth weighing TPO against PVC, spray foam, and built-up roofing — and we'll help you choose the best fit for your building and budget.
