Severe thunderstorms and tornado-warned storms move through the Tulsa metro every spring. We document wind damage to commercial roofs for the insurance claim.
Tulsa's severe-weather season runs roughly April through June, when the same upper-air pattern that produces tornado warnings across northeast Oklahoma also produces straight-line wind events and derecho-style thunderstorm complexes that don't make headlines the way a tornado does but still put sustained gusts across a commercial roof for the better part of an hour. Buildings near the American Airlines maintenance base, along the I-44 industrial belt, and in the Broken Arrow and Owasso employment corridors all sit under that same seasonal pattern.
Wind damage on a commercial low-slope roof rarely looks dramatic from the ground. What actually fails is the membrane's attachment at the perimeter and at penetrations — edge metal that lifts under uplift pressure, flashing that pulls loose at a curb or a parapet, seams that separate where the membrane wasn't fully adhered or welded. The field of the roof can look intact while the edges and details, where wind load concentrates, have already failed.
We inspect the perimeter and every penetration first, because that's where uplift damage starts. We photograph displaced or lifted edge metal, separated seams, and flashing pulled away from curbs, parapets, and equipment mounts, and we note the displacement pattern — which direction the membrane moved, which side of the building took the worst of it — because that pattern is what confirms wind as the cause rather than an installation defect or age-related failure. We distinguish wind-related displacement from pre-existing conditions the same way we do on any claim: the scope only includes what the storm actually caused.
For storms that carried a tornado warning or a documented wind speed, we pull National Weather Service storm reports and Oklahoma Mesonet wind data for the nearest station to establish the wind speed the building experienced during the event. That record ties the roof damage to the specific storm rather than leaving the cause as a general assertion.
A wind damage scope typically includes re-securing or replacing displaced edge metal and flashing, resealing or replacing separated seams, and — where uplift damage is extensive enough to have compromised the membrane's wind-load performance across a section — a broader repair of that section rather than spot patching individual failure points. Where code requires updated fastening patterns or edge securement details on the repaired section (a common requirement when the original installation predates current wind-uplift standards), we include that in the written scope so the repaired roof meets current code, rather than a like-for-like replacement of what failed.
We're your roofing contractor, not a public adjuster — we document and substantiate the wind damage so you and your adjuster work from an accurate scope.
Wind damage typically shows up at the perimeter and penetrations — lifted edge metal, separated seams, displaced flashing — rather than as impact marks scattered across the field. We inspect those failure points first on a suspected wind-damage claim.
Yes, if the roof shows wind damage consistent with the storm. We pull National Weather Service storm reports and Mesonet wind data for the event regardless of whether a tornado was confirmed — straight-line wind from the same storm system can cause the same category of roof damage.
Almost always. Perimeter and penetration damage on a low-slope roof isn't visible from the ground or from inside the building unless it's already caused a leak. That's why we inspect the whole perimeter and every penetration on a suspected wind event, beyond the areas visible from an elevated vantage point.
If the original installation predates current wind-uplift fastening standards, code may require the repaired section to meet the current standard rather than a like-for-like replacement. We include that requirement in the scope where it applies.
National Weather Service storm reports and Oklahoma Mesonet station data for wind speed and timing at the nearest reporting point to the building, tied to the specific storm date.
We'll inspect the perimeter and penetrations, document what the storm did, and put a written scope in front of you and your adjuster.
