White single-ply membrane roofs installed and repaired statewide
TPO Roofing Systems in Oklahoma Built for Hail, Heat, and Wind
TPO Roofing Systems in Oklahoma give commercial property owners a white, heat-reflective membrane that shrugs off hail, wind uplift, and 100-degree summers. We install, repair, and maintain TPO for warehouses, retail centers, schools, and metal buildings from Broken Arrow to Hollis. If your flat roof is leaking, ponding, or cooking your utility budget, we walk it, measure it, and quote it free.
What TPO Roofing Systems in Oklahoma Actually Involve
TPO Roofing Systems in Oklahoma means a single-ply thermoplastic polyolefin membrane, usually 45 to 80 mils thick, heat-welded into one continuous sheet across your flat or low-slope roof. We mechanically fasten or fully adhere the membrane over roof insulation board, then weld every seam with a hot air welder and roll it tight with a seam roller. Edges get flashing, termination bars, and fasteners set to code. The result is a white roof that reflects sunlight instead of soaking it up.
Oklahoma commercial roofs take a beating no coastal roof does. Spring hail dents membrane and insulation. Summer surface temps push past 160 degrees. Winter wind gusts test every seam and fastener. That is why we spec TPO membrane roofing Oklahoma buildings can actually survive: puncture-resistant sheets, reinforced seams, and drainage planned around ponding water. We also handle TPO roof repair Oklahoma commercial clients call about after every storm, from seam separation to flashing failures.
Every TPO Roofing System we install includes the membrane, insulation, fastening, flashing, welding, and testing as one package. You are not buying pieces. You are buying a finished roof with a manufacturer warranty in your name. Here is what shows up in the scope.
01
✓
TPO Membrane and Insulation
45 to 80 mil TPO membrane over polyiso or EPS roof insulation board, sized to your target R-value. We use Carlisle SynTec, Firestone Building Products, GAF, or Johns Manville membrane depending on the warranty tier you choose.
02
✓
Heat-Welded Seams
Every seam welded with a hot air welder and rolled with a seam roller. We probe-test welds before sign-off. This is what makes a TPO roof a single watertight sheet instead of a patchwork of glued strips.
03
✓
Flashing and Edge Detail
Curbs, drains, penetrations, parapet walls, and edges get flashing, termination bars, and fasteners set to code. Flashing failures cause more leaks than membrane failures, so we detail every one.
04
✓
Drainage and Ponding Fixes
We check slope and drainage during the roof walk. If ponding water sits more than 48 hours after a rain, we add crickets, tapered insulation, or new drains so water leaves the roof instead of cooking the membrane.
05
✓
Warranty Registration
We register your manufacturer warranty and hand you the paperwork. Warranties run 15 to 30 years depending on system. NDL coverage is available on qualifying installations through our manufacturer certifications.
How it works
How Our TPO Roof Installation Works
We walk the roof, check drainage, probe soft spots, and scan wet insulation with an infrared thermal camera. You get photos, measurements, and a written scope within 48 hours. No charge, no pressure. If a repair beats a replacement, we tell you that.
We remove the old modified bitumen, EPDM membrane, or built-up roofing felt down to the deck, or recover over it if code and moisture readings allow. Wet insulation board comes out. We inspect the deck for rust and rot, then repair what we find.
We lay polyiso or EPS insulation board to your target R-value, then install the TPO membrane. Mechanically fastened or fully adhered, your call. We detail curbs, drains, penetrations, and edges with flashing and termination bars before the first seam is welded.
Every seam gets welded with a hot air welder and rolled with a seam roller. We probe-test welds and water-test drains. A roof crawler and moisture meter confirm no wet spots remain. This is the step that decides whether your roof lasts 20 years or 8.
We magnet-sweep the lot for fasteners, haul off every scrap, and walk the finished roof with you. You get manufacturer warranty paperwork and a maintenance schedule. We come back at the one-year mark to check seams and drainage at no charge.

Tools & methods
Tools and Methods We Use on TPO Roofs
01
✓
Hot Air Welder
Fuses TPO membrane seams at roughly 1,000 degrees. A properly welded seam is stronger than the membrane itself, which is why we probe-test every one.
02
✓
Seam Roller
Presses the welded seam flat while it is still hot, closing any gap or air pocket. Skipping this step is the number one cause of seam separation.
03
✓
Infrared Thermal Camera
Finds wet insulation under the membrane without cutting the roof open. We scan before every quote and after every repair.
04
✓
Moisture Meter
Confirms wet or dry readings at specific points on the roof deck and insulation. Pairs with the thermal scan to map the exact repair area.
05
✓
Roof Crawler
Carries membrane rolls and equipment across the roof without dragging them over finished seams. Protects the membrane during installation.
06
✓
Power Broom
Cleans the deck and membrane surface before adhesion or welding. Dust and debris cause weak welds and adhesive failures.

TPO Roofing Systems
Broken Arrow Warehouse: EPDM to TPO
An 18,000-square-foot warehouse had a 15-year-old EPDM membrane with three active leaks, separated seams, and wet insulation across roughly 2,000 square feet. Summer cooling costs were climbing and the owner was patching leaks every few months.
After: We tore off the EPDM, replaced saturated insulation board, and installed 60 mil TPO membrane mechanically fastened to the steel deck. Leaks stopped immediately, and the owner reported about an 18 percent drop in summer cooling cost.
A spring hail storm punched holes across three tenant roof sections of a retail strip center. Water was dripping into two storefronts and the owner needed documentation for an insurance claim fast.
After: We tarped the same day, scanned with an infrared thermal camera, and documented the damage with photos and moisture readings. Repairs used matching TPO membrane and new flashing at every penetration. Tenants never closed.
A mini-storage facility had chronic ponding water on an old modified bitumen roof. Water sat for days after every rain, seams were failing, and the owner was calling for repairs monthly.
After: We corrected slope with tapered insulation, installed 80 mil TPO membrane for hail resistance, and replaced all flashing and drain details. Ponding is gone and the roof has been leak-free through two storm seasons.
Flat commercial roofs fail in predictable ways. Here are the ones we see most on Oklahoma buildings, and how we fix them without selling you a roof you do not need.
We scan with an infrared thermal camera and moisture meter to map the wet zone, cut out the saturated insulation, and weld in new TPO membrane. You fix the actual problem, not just the stain on the ceiling tile.
↗02
Ponding water sitting for days after rain
We correct slope with tapered insulation or crickets, clear or add drains, and verify drainage after the next rain. Ponding fixed at installation stays fixed for the life of the roof.
↗03
Hail damage and membrane punctures
We document hail damage with photos and moisture readings for your insurance claim, then repair punctures and replace damaged sections. If damage is widespread, we quote a full TPO replacement with upgraded hail-rated membrane.
↗04
Seam separation and wind uplift
We re-weld failed seams, add fasteners where uplift ratings were not met, and re-secure edges and corners. New installations get fastening patterns designed to SPRI wind-uplift standards for your building height and exposure.
“Our 18,000-square-foot warehouse roof was leaking in three spots and the old EPDM was shot. De La Cruz tore it off, added insulation, and installed 60 mil TPO in eight days. Summer electric bill dropped about 18 percent. They cleaned the lot better than they found it.”

“Hail punched holes in our retail center roof last spring. They tarped it the same day I called and had the TPO repairs done within a week. Photos and moisture readings went straight to my adjuster. No runaround, no surprise charges.”

“We got three quotes for a new flat roof on our fellowship hall. De La Cruz was the only one who got on the roof, scanned for wet insulation, and explained the difference between recover and tear-off. TPO install was clean, and they came back at one year to check seams like they promised.”

Good questions
Frequently Asked Questions About TPO Roofing Systems
Most Oklahoma commercial TPO installations run $6 to $12 per square foot installed in 2026, depending on membrane thickness, insulation R-value, and whether we tear off or recover. A 10,000-square-foot warehouse roof typically lands between $60,000 and $120,000. Repairs run $400 to $2,500 for most seam, flashing, or puncture fixes. We quote free after a roof walk.
Yes. TPO handles Oklahoma's hail, 100-degree summers, and high wind better than most single-ply options. The white membrane reflects heat, the heat-welded seams resist wind uplift, and 60 to 80 mil sheets take hail impacts that puncture thinner membranes. We spec thicker membrane and reinforced fastening in the hail belt from Lawton to Enid.
A properly installed TPO roof lasts 20 to 30 years in Oklahoma with annual maintenance. Hail and ponding water are the two things that shorten that. We recommend a yearly inspection each spring, plus a post-storm check, to catch seam separation and flashing failures before they turn into roof leaks.
TPO reflects heat and welds into stronger seams; EPDM is thicker, cheaper upfront, and handles UV well but uses adhesive seams that can lift in Oklahoma wind. For energy efficiency and hail resistance, TPO usually wins. For a tight budget on a low-risk roof, EPDM membrane still works. We install both and will tell you which fits your building.
