TPO Roofing · St. Louis Commercial

TPO roofing
for commercial buildings.

Thermoplastic Polyolefin — the modern flat-roof standard. Energy-efficient, weldable seams, 20–30 year life. KPro is Mule-Hide Preferred.

What it covers

Why TPO is the right call for most flat roofs.

If you own a commercial building in St. Louis with a flat or low-slope roof, TPO is probably what you should be installing.

Heat-welded seams. Unlike older EPDM rubber roofs that rely on adhesive seams, TPO welds together with hot air. The seam is stronger than the panel itself.

Reflective white surface. Bounces sunlight, reduces cooling load. ENERGY STAR rated.

20–30 year life. If installed by a certified contractor (us), warranties run 20–30 years from major manufacturers.

Easier repairs. Patches weld in clean. EPDM patches don't.

Frequently asked

TPO Roofing FAQ

TPO vs. EPDM — what's the difference?+

EPDM is rubber, glued seams. TPO is thermoplastic, welded seams. TPO is whiter (more reflective), seams are stronger, and it's the modern industry preference for new commercial flat roofs.

Can you patch a TPO leak?+

Yes. We heat-weld a patch over the affected area. If the underlying issue is bigger (drain failure, structural movement), we address that too.

How much does TPO cost?+

Commercial TPO runs $7–$14 per square foot installed depending on building access, drain count, and insulation requirements. Smaller jobs sometimes higher per-foot due to mobilization.

Do you maintain it after install?+

Yes. We offer annual inspection programs that catch seam separation, debris buildup, and drain blockages before they cause leaks. Most commercial customers wish they'd started this years earlier.
