Hail rarely puts a hole in a roof. What it does is fracture the mat underneath the surface, which you can’t see from the ground and often can’t see from the roof either. The shingle keeps shedding water, so nothing leaks, and then the roof fails five or ten years early.

That gap between when the damage happens and when it shows is the whole problem. Here’s what to look for, what your policy will and won’t do, and what Tennessee law says about the contractors who show up after a storm.
What Hail Actually Does to a Shingle
Two things, and only one of them is visible.
The obvious one is granule loss. Hail knocks the ceramic granules off the surface, leaving dark spots where the asphalt underneath is exposed. Those granules are the shingle’s UV protection, and once they’re gone that spot ages far faster than the rest of the roof.
The one that matters more is bruising. A hailstone that hits hard enough fractures the fiberglass mat inside the shingle without breaking the surface. Press on it and it feels soft, like a bruise on fruit. The shingle looks fine and keeps working, but the mat is what gives it structure, and a fractured mat fails early.

This is why leaks almost never show up right after a hailstorm, and why a roof that looks fine from the driveway can still have a claim on it.
How Big Does Hail Have to Be?
As a rough rule, hail around an inch across, roughly a quarter, is where asphalt shingles start taking real damage. Golf ball sized and up does obvious damage.
Two things move that threshold:
- Roof age. An older roof that’s already lost granules and gone brittle can be damaged by hail well under an inch. A two-year-old roof might shrug off the same storm.
- Wind. Hail driven sideways at 60 mph hits harder than hail falling straight down, and it concentrates damage on whichever slope faced the storm.
So the honest answer is that hail size tells you whether to look, not whether you have damage.
How to Spot It Without Getting on the Roof
Stay on the ground. This is all visible from there, and it’s the same evidence an adjuster looks for.
Check the soft metal first. It dents before shingles bruise, and it’s at eye level:
- Gutters and downspouts, especially the flat faces
- Metal vent caps, flashing and roof vents
- The aluminum fins on your AC condenser
- Mailbox, garage door, grill lid, anything metal in the yard
- Window screens and vinyl siding on the storm-facing side
If those are dented, the roof took the same hits. If none of them are marked, the roof probably came through it.
Then look at where the water goes. A pile of granules at the bottom of a downspout or on the splash block after a storm is granule loss coming off the roof. Some granule shedding is normal on a new roof; a sudden pile after a hailstorm is not.
One more tell: hail damage is random. It’s scattered across the slope with no pattern. Damage in a straight line or concentrated in one area is usually something else, like foot traffic or a tree limb.
Why Waiting Is the Expensive Choice
Insurance policies have notice requirements and time limits for filing. They vary by carrier and by policy, and some are shorter than people expect, so the date on your policy matters more than any rule of thumb.
The practical risk is this. Wait long enough and the carrier can reasonably argue the damage came from a later storm, or from ordinary wear, and you lose the connection to a specific covered event. Documentation right after a storm is worth far more than documentation two years later.
An inspection after a significant storm costs you nothing and either clears the roof or starts a claim while it’s still clean.
What Insurance Does and Doesn’t Cover
Hail is a covered peril on essentially every homeowners policy. What varies is how much of the roof they’ll pay for and on what basis.
- Replacement cost versus actual cash value. Replacement cost pays what a new roof costs. Actual cash value pays the depreciated value, which on a fifteen-year-old roof is a fraction of it. Carriers have been moving older roofs onto actual cash value, so check which one you have before you need it.
- Cosmetic damage exclusions. Increasingly common on metal roofs. The carrier pays for a roof that leaks, not one that’s merely dented.
- Your deductible. On many Tennessee policies wind and hail carry a separate, higher deductible than the rest of the policy, sometimes a percentage of the dwelling value rather than a flat amount.
- Matching. Whether the carrier owes you a full roof when the damaged shingle is discontinued is a recurring fight, and it’s worth asking your agent how your carrier handles it.
What helps every one of those conversations is documentation: dated photographs, the date and time of the storm, an inspection report that identifies the damage and ties it to that event, and a written scope from a contractor.
What Tennessee Law Says About Roofers and Storm Claims
This is worth knowing before you sign anything, because Tennessee has rules specific to residential roofing that most homeowners have never heard of.
A roofer cannot act as your public adjuster unless they’re licensed as one. Tennessee Code section 62-6-605 says a residential roofing services provider shall not act or hold out as being a public adjuster unless licensed under the state’s public adjuster rules. So a contractor promising to handle your claim for you, negotiate with your adjuster, or get your claim approved is describing work they may not be licensed to do.
That doesn’t mean a roofer can’t help. We can inspect, document what we find, provide a written scope and meet the adjuster on site to walk the roof together. That’s normal and useful. Representing you in the claim is a different thing.
You can cancel if your insurer denies it. Tennessee Code section 62-6-602 gives you the right to cancel a residential roofing contract if your insurer tells you in writing that all or part of the claim isn’t a covered loss. You have to give the contractor written notice before midnight on the third business day after you receive that written notice from the insurer.
That exists specifically so you’re not locked into a roof you assumed insurance was paying for. If a contractor wants you to sign a contract before the claim is settled, that provision is the one to know about.
We’re roofers, not lawyers, and this is a summary rather than legal advice. If you’re in a dispute, talk to someone who does this for a living.
About the Contractors Who Appear After a Storm
They’re a real thing and they follow hail. Out-of-state plates, door knocking within days, high pressure, and gone by the time the roof leaks.
What to check before you sign anything:
- A Tennessee contractor license, and insurance certificates you can actually see
- A local address that isn’t a hotel or a PO box
- How long they’ve been in this market, not how long the company has existed somewhere
- Who honors the workmanship warranty in year six, and whether they’ll still be here
- Whether they’re asking for money up front. Tennessee regulates deposits and payments on residential roofing work.
- Anything sounding like an offer around your deductible. Your deductible is your obligation under your policy, and a contractor offering to make it disappear is telling you something about how they do business.
None of that means every out-of-town contractor is a problem. It means the checks are cheap and the consequences of skipping them aren’t.

I’m a bit surprised that there’s really nothing that isn’t safe from hail. Hail storms are actually a bit common where my friend moved to. She said that it’s a good idea to have your roof inspected after a big storm.
I’m glad you said that a roof that’s meant to last 50 years might last 10 if it’s damaged by hail. A large storm passed through my area last week, and there were pieces of hailing the size of coins falling on the roof. Maybe I should have a roof repair service take a look at the shingles to see if they’ve been damaged by the storm.
