— TPO Roofing
Heat-welded TPO membrane systems for commercial, industrial, and low-slope buildings — reflective, energy-efficient, and backed by manufacturer warranties. Serving Dallas, Fort Worth, and the surrounding DFW communities.
TPO — thermoplastic polyolefin — is the go-to membrane for commercial flat roofs in Texas. The bright white reflective surface keeps rooftops dramatically cooler, lowering HVAC bills for retail, warehouse, and multifamily buildings.
Knox Roofing installs TPO systems with heat-welded seams (the strongest seam type in the industry), proper insulation, and manufacturer-backed 20-30 year warranties. Our commercial crews handle projects from small retail to 100,000+ sq ft warehouses.

— Why Knox
Four things we do on every TPO project — the details that separate a 10-year roof from a 30-year roof.
Up to 30% lower cooling costs versus black roofs — meaningful in Texas summer.
TPO seams are welded, not glued — stronger than the membrane itself.
TPO carries the highest UL fire rating, standard on every install.
Manufacturer-backed membrane warranties — real, transferable, and enforceable.
We'll assess your building, scope the right TPO assembly, and give you a transparent, warranty-backed quote — no pressure.
Schedule Free InspectionFrom site assessment to warranty registration, here's how a Knox TPO install runs.
We measure, inspect substrate condition, count penetrations, and document the existing system to scope the project accurately.
Polyiso insulation, cover board, and substrate prep sized to your building code, energy targets, and hail exposure.
Membrane rolled, fastened, and heat-welded by our commercial crew — every seam probed before we leave the roof.
Final water test, punch walk with the building owner, and manufacturer warranty registration on your behalf.
20–30 years for quality membranes installed properly. The seams — welded, not glued — are TPO's secret to longevity.
For commercial cooling costs in Texas, yes. The reflective surface typically pays for itself within 5–7 years.
Yes — with adequate insulation and a quality cover board underneath. We can specify Class 4 impact-rated assemblies.
Standard rolls are 10–12 feet wide, so seams are minimized. We plan the layout to limit the seam count over high-traffic areas.
