Commercial Storm Response:After Hail Hits Your Flat Roof
Hail damage on a flat roof rarely looks like much from the ground. It shows up as a leak weeks later, after water has already reached the insulation.
The Tulsa metro saw hail and damaging wind several times in spring 2026.
Why Hail Damage on Flat Roofs Hides
Hail can puncture a membrane, crush the insulation below it, or weaken seams without leaving an obvious hole. Water then works in slowly. By the time a ceiling stain appears, wet insulation may have spread well beyond the original impact.
TPO
Hail can fracture the membrane or crack it at the seams, especially as the roof ages and the membrane loses flexibility.
EPDM
Impacts can bruise the rubber and crush the insulation underneath, leaving soft spots that hold water.
Modified bitumen
Hail knocks granules loose and can fracture the reinforcement inside the sheet, which weakens it over time.
Metal
Beyond visible dents, hail can damage panel coatings, seams and fasteners, which lets corrosion and water in later.
What to Do in the First 72 Hours
Make it safe
Keep people out of areas with active leaks, sagging ceilings or wet electrical. Don't walk a damaged roof yourself.
Photograph inside and out
Take photos of ceiling stains, wet floors, damaged equipment and anything you can safely see outside, including hail on the ground.
Note the date and hail size
Write down when the storm hit and how big the hail was. A coin or ruler in a photo helps.
Call for an inspection first
Stop active water if you can, but have the roof inspected and documented before permanent repairs are made.

What IGR Roofing Does After a Storm
You own and file the claim with your insurer. We are your roofing contractor, not a public adjuster.
Inspect
We walk the whole roof, not just the area over the leak.
Document
Dated photos and measurements of every damaged area.
Compare
We compare what we find against your Baseline Condition Record if one exists.
Meet the adjuster
We can meet your adjuster on the roof and walk the damage together.
Repair
Temporary repairs to protect the building, then permanent repairs with a Plain-Language Scope Sheet.
Plan members come first
Members of a Preventative Maintenance Agreement get post-storm checks after significant hail, and IGR contacts plan members first. Their Baseline Condition Record is already on file, so damage can be compared against a known starting point.
Local, Before and After the Storm
Out-of-town crews follow the hail and leave when the work dries up. Your roof and its warranty stay behind.
