Flat roofs don't drain like sloped roofs. Water sits instead of running off. That fundamental difference means flat roofing requires specialized materials, installation methods, and drainage solutions. Best Roofers Near Me | Oklahoma City installs and repairs TPO, PVC, EPDM, and modified bitumen flat roofing systems throughout Oklahoma City.

PVC membrane is the only flat roofing material that resists animal fats and chemical exposure from rooftop grease exhaust. If you own a restaurant or commercial kitchen in Oklahoma City, PVC is the right choice. TPO and EPDM will deteriorate when exposed to kitchen grease venting.

Flat Roofing FAQ

Flat roofing in Oklahoma City runs $5-$12 per square foot depending on the membrane type, insulation requirements, and drainage design. TPO and EPDM are mid-range, PVC is higher, and coatings are the most affordable for qualifying roofs.

Ponding happens when the roof lacks adequate slope to drains or edges. Causes include compressed insulation, clogged drains, building settlement, or the original installation didn't include tapered insulation. We fix it with tapered ISO boards that create positive drainage.

TPO and PVC: 15-25 years. EPDM: 20-30 years. Modified bitumen: 15-20 years. Lifespan depends on proper installation, drainage, and maintenance. Regular inspections catch small issues before they shorten roof life.

TPO is more energy-efficient (reflective white) and has stronger seam welds. EPDM is proven over 50+ years and typically costs less. Both are solid choices. We recommend TPO for energy savings and EPDM for budget-conscious projects.

A roof coating is a liquid-applied membrane, usually silicone or acrylic. That extends the life of an existing flat roof by 10-15 years. It works when the existing membrane and insulation are in reasonable shape. We core sample and moisture test to determine if your roof qualifies.
