Hail Damage on Your Roof: How to Spot It and What to Do Next
Hail is the most misunderstood kind of roof damage, because the worst of it hides. A hailstorm rarely punches an obvious hole. Instead it bruises the mat under the shingle and knocks off the granules that protect it — damage you often cannot see from the ground, and sometimes cannot see from the roof without knowing exactly what to look for.
That invisibility is why so many hail claims get missed until the roof starts leaking months later, long after the insurance filing window has closed. Here is what hail damage actually looks like, why it matters, and what to do after a storm in Western North Carolina.
What does hail damage on a roof actually look like?
On asphalt shingles, hail leaves round bruises — spots where the impact cracked the mat and dislodged the protective granules. Run a hand over one and it feels soft, like a bruise on an apple. Around it you will often see clusters of missing granules exposing the darker asphalt underneath.
The easiest place to confirm a hailstorm, though, is the soft metal. Hail dents gutters, downspouts, valley flashing, vent hoods, and AC fins in a way that is obvious and hard to argue with. If those are dimpled, your roof was hit too — even if the shingles look okay from the ground.
Why hail damage matters even if the roof is not leaking
A bruised shingle has lost the granule layer that shields it from UV. Exposed to the sun, that spot dries out, cracks, and fails years earlier than it should. So a roof that looks fine today can spring leaks in two or three winters — after the storm is a distant memory and the insurance claim window has closed.
That is the trap with hail. The damage is real and the clock is ticking, but nothing looks urgent, so homeowners wait. By the time the leak arrives, the carrier can argue the damage is old wear rather than a specific storm, and the claim gets denied.
What to do after a hailstorm
Move quickly but safely. The steps below protect both your home and your ability to file a claim.
- Stay off the roof. Check from the ground and from soft metals — gutters, downspouts, screens, and vents — for dents.
- Note the date and time of the storm. Carriers cross-reference claims against weather records for that location.
- Photograph what you can see safely: dented gutters, dinged flashing, granules washed into downspout splash zones.
- Book a free professional inspection soon, while the damage is fresh and provable.
- Do not file a claim before you know you have one. An honest inspection tells you whether the damage will support a claim, so you do not spend a claim on nothing.
How a hail inspection should work
A proper hail inspection uses the same method your insurance adjuster does: a marked test square, usually 10 feet by 10 feet, where the inspector counts and documents impacts. That is what makes the findings hold up in a claim. The inspector should also check everything the storm touched — gutters, downspouts, vents, screens, and siding — because hail rarely hits shingles alone.
You should come away with photos and a straight answer: an honest repair quote if the damage is light, or carrier-grade documentation and a claim recommendation if it is real. Either way, the inspection is free and the decision is yours.
How big does hail have to be to damage a roof?
There is no universal cutoff, but a rough guide holds up well. Hail around 1 inch — about the size of a quarter — is where asphalt shingles start to bruise. Stones from 1.25 inches up (half-dollar to golf-ball size) routinely cause damage that supports an insurance claim. Wind matters as much as size: driven hail hits far harder than hail falling straight down, so a smaller stone in a violent storm can do the work of a larger one.
The roof itself changes the threshold. An older, sun-baked, or already-brittle roof bruises and cracks at smaller hail sizes than a newer one, which is why two neighbors can walk out of the same storm with very different damage. A hail-size chart is a starting point, not an answer — the roof has to be looked at.
- Pea to marble (under 1"): usually cosmetic, occasionally damaging on old roofs.
- Quarter (1"): the common threshold where asphalt bruising begins.
- Half-dollar to golf ball (1.25–1.75"): routinely claim-worthy damage.
- Larger than golf ball: expect widespread damage, often a full replacement.
Does hail damage every roof the same way?
No. On asphalt shingles, hail knocks the protective granules loose and bruises the mat underneath — the classic damage that fails early. On metal roofs, hail dents panels and, more important for a claim, can microfracture the coating, so a metal roof rarely leaks right away but can corrode years later. Wood shake splits along the grain, and older, brittle tile cracks.
Soft metals tell the story fastest. Gutters, downspouts, valley flashing, vent hoods, and AC fins all dent visibly and are the easiest proof your property was hit — even when the shingles look fine from the ground. If those are dimpled, get the roof looked at before the claim window closes.

Frequently Asked Questions
How long after a hailstorm can I file a claim?
Policies carry filing windows that vary by carrier, and fresh damage is far easier to prove than old damage. The safe move is a free inspection within days of the storm, even if you decide to file later.
Will one hailstorm really justify a new roof?
Sometimes. It depends on the density and size of the impacts across the roof. Light, scattered damage may only need a repair; widespread bruising across multiple slopes can justify a full replacement under your policy. The test-square inspection settles it.
Does hail damage metal roofs too?
It can dent panels and, more importantly for a claim, microfracture the coating. Metal rarely leaks immediately from hail, which is exactly why post-storm documentation matters.
