Commercial flat roof repair across the Tulsa metro — parapet flashing, seam failures, drain corrections, hail punctures. Written scope and documented repair with no replacement upsell pressure.
Many of our Tulsa repair clients have been told by a prior contractor that the entire roof needs replacement. We verify that claim with moisture cores and a systematic surface inspection. When replacement is genuinely warranted, we say so and explain why. When repair extends serviceable life another eight to twelve years at a fraction of the replacement cost, we scope the repair and document the reasoning.
Parapet flashing separation: Tulsa commercial buildings experience parapet flashing failures from two compounding forces — thermal cycling that swings from sub-zero Uri-event lows in February to 165-degree-plus surface temperatures in July, and wind uplift at parapet caps during spring storm events. Parapet walls on pre-2000 commercial buildings were typically detailed without the slip-sheet provision that allows wall movement under thermal stress. The result is a gap at the base of the parapet where water enters laterally, wets the insulation, and corrodes the deck below. Repair scope: remove the compromised flashing, install a new base flashing with a movement-accommodating detail, and terminate with a properly embedded counter-flashing.
Seam separation on TPO and EPDM: Heat-welded TPO seams and factory-seamed EPDM laps fail at under-quality installation points or at areas of unusual membrane stress — near roof drains, at HVAC equipment curb corners, and along the perimeter where tornado-alley wind-uplift loads are highest during severe weather events. Repair scope: clean and dry the failed seam area, apply compatible seam repair tape or re-weld with a hot-air gun, and probe-test the repair. Seam failures running more than fifty linear feet in a concentrated zone shift the conversation toward membrane field section replacement.
Hail puncture and surface damage: Tulsa County's position in one of the highest hail-frequency corridors in North America means hail impact damage is a routine repair category, not an occasional one. Post-storm, we distinguish surface impact marks and granule loss — which are cosmetic and repairable — from actual membrane breach that requires patch or section replacement. Impact damage that penetrates to the insulation layer requires immediate repair because Tulsa's spring humidity will saturate exposed insulation within weeks if left unaddressed.
We pull moisture cores in five to ten representative locations on any Tulsa commercial roof where insulation saturation is suspected — near drains, at parapet corners, mid-field, and anywhere the building's facility manager has reported ceiling staining below. If more than twenty-five percent of cores read wet, repair economics no longer work. Recovering saturated insulation traps the moisture below the new membrane, voids the manufacturer warranty, and accelerates metal deck corrosion — a particular concern on the light-gauge steel deck common in Tulsa's 1970s and 1980s commercial construction. In that scenario, replacement is the honest recommendation.
When cores read dry and the failure is localized — a parapet run of forty linear feet, a cluster of failed seams near one drain, a single ponding area without systemic saturation — repair is the right call and we scope it as repair. We do not recommend replacement on roofs that have serviceable life remaining. Our work in this market is built on long-term facility relationships, and those relationships depend on straight recommendations.
Every repair we close out includes a photo-keyed map of repair locations on the roof plan, before-and-after photos at each repair point, the product data sheets for every material applied, and a written service record that goes into the building's roof asset file. In Tulsa's hail climate, this documentation matters operationally: manufacturer warranty claims require evidence of documented maintenance, and post-storm insurance documentation requires a legible repair history that demonstrates the building was properly maintained before the event.
For buildings on our maintenance contracts, repair documentation feeds directly into the annual condition report. The building owner accumulates a running asset record across inspection cycles — not a collection of disconnected invoices that no one can reconstruct at property sale or insurance claim time.
Fixed scope after a documented inspection. We do not run time-and-materials repair on commercial roofs. After we walk the roof and document the failure points, we deliver a fixed-price written scope. If we open a repair area and discover additional damage that changes the scope, we stop, photograph it, and call you before proceeding. The invoice reflects what we scoped, not what we encountered on the fly.
Yes. Most manufacturer NDL warranties allow any credentialed contractor to perform repair work, as long as repair materials are compatible with the existing system and the repair is documented per the manufacturer's protocol. We submit repair documentation to the manufacturer's warranty department after closeout so the repair is on record and does not create a gap in the warranty maintenance history.
Downtown Tulsa, Midtown, and the Arts District — including the BOK Tower corridor and ONEOK Plaza area — we mobilize within four business hours. Inner suburbs including Broken Arrow, Owasso, Bixby, and Jenks are same-day. After-hours calls for active water intrusion into occupied space route to an on-call project manager who can dispatch an emergency crew same-evening or first light. Buildings on our maintenance contracts receive priority dispatch.
