What Hail Damage Looks Like on an Oklahoma City Roof
Hail damage on an asphalt-shingle roof usually looks like dark, soft bruises where granules have been knocked off, often in a random pattern. Much of it is not visible from the ground — which is why a professional inspection after any significant Oklahoma hail storm is the only reliable way to know.
Signs you can often see from the ground
- Granules collecting in gutters and at downspout splash blocks
- Dents in metal vents, flashing, gutters, and gutter screens
- Dings on the AC fins or fence and deck surfaces (a hail-size indicator)
- Shiny spots or dark bruises where protective granules are gone
Hail size and what it typically does
Hail size is the single best predictor of whether an asphalt roof took functional damage. Adjusters and inspectors think in these rough bands, though age, shingle line, and the angle the stones fell all shift the outcome — an older, brittle roof bruises at sizes a newer one shrugs off.
| Hail size | Common comparison | Typical effect on an asphalt roof |
|---|---|---|
| ¾ inch | Penny | Usually cosmetic; granule loss on older or worn shingles |
| 1 inch | Quarter | Threshold where functional bruising commonly begins |
| 1¼–1½ inch | Half dollar to ping-pong ball | Bruising and granule loss likely; soft metals dented |
| 1¾ inch+ | Golf ball and larger | Functional damage probable; full replacement often warranted |
Cosmetic vs. functional damage — the distinction that decides claims
Carriers separate cosmetic damage from functional damage, and it is the difference between a denied claim and an approved replacement. Functional damage means the shingle's ability to shed water has been compromised — the mat is bruised or fractured beneath the surface, so the granule layer protecting the asphalt is gone and UV will now break it down. That bruise is soft to the touch, like a dent in drywall, and often invisible in a photo taken from the ground.
If hail of an inch or more fell on your address, get a documented inspection even if the roof looks fine from the driveway — functional bruising is specifically the kind of damage you cannot see from the ground, and it is the kind that gets claims approved.
What to do after a hail storm
- Note the storm date — every deadline that follows runs from the date of loss
- Photograph soft-metal evidence now: gutters, downspouts, vents, and AC fins
- Get a free, documented inspection before assuming you're fine
- Don't sign anything authorizing work before you understand the scope
- If damage is found, file the claim and let an experienced contractor meet the adjuster
How long you actually have
Oklahoma law sets a floor on the filing window. Under 36 O.S. §1250.5(7), a policy that limits the time to file a wind or hail roof claim must still allow filing up to twenty-four months after the date of loss when the damage was not evident without an inspection — which is precisely the situation with hail bruising. That is a backstop, not a plan: separate and shorter deadlines usually govern filing suit, and replacement-cost policies commonly require the repair itself to be completed within six months of the loss before the withheld depreciation is released. Read your own policy for the specific numbers.
Frequently asked questions
Can I see hail damage from the ground?
Sometimes — dented gutters and granules in downspouts are visible. But functional shingle damage usually isn't, so a professional inspection after a hail storm is the only reliable check.
What size hail damages a roof?
Functional damage to asphalt shingles commonly begins around 1 inch (quarter-sized) hail, and becomes probable at 1¾ inches (golf ball) and above. Smaller hail is often cosmetic, though an older or already-worn roof can bruise at sizes a newer roof would shrug off.
What is the difference between cosmetic and functional hail damage?
Cosmetic damage affects appearance only. Functional damage means the shingle can no longer shed water properly — the mat is bruised or fractured under the surface and the protective granule layer is gone, so UV begins breaking down the asphalt. Carriers approve claims on functional damage, and it is usually invisible from the ground.
How long do I have to file a hail claim in Oklahoma?
Under 36 O.S. §1250.5(7), a policy limiting the filing window for wind or hail roof damage must still allow claims up to 24 months after the date of loss when the damage was not evident without inspection. Shorter deadlines often apply to filing suit, and replacement-cost policies commonly require repairs completed within six months of the loss to release withheld depreciation.
