Most homeowners never see their own roof. So when a storm rolls through and someone knocks on the door offering a free inspection, it is genuinely hard to know whether you have a problem or whether you are being sold one.
Here is what hail damage on a roof actually is, what it looks like, how to tell it apart from ordinary wear, and how to form your own opinion before anyone climbs up there.
The short version
- Hail damage is a bruise, not a hole. A dark round spot where the granules are gone, soft when you press it.
- Check the soft metal first, from the ground. Gutters, screens, the AC unit. Hail big enough to hurt shingles almost always dents metal.
- One inch is roughly where shingle damage starts. Below that, expect damage to screens and paint before the roof.
- Six common things look like hail and are not — blistering is the big one, and it is the fastest way to a denied claim.
- Photograph everything in the first few days. Fresh damage looks different from old damage, and that difference decides claims.
What hail actually does to a shingle
An asphalt shingle is three layers: a fiberglass mat for strength, asphalt to waterproof it, and a coat of ceramic granules on top that shields the asphalt from ultraviolet light.
When a hailstone hits hard enough, two things happen at once. The granules scatter, exposing the asphalt. And the mat underneath fractures, even though nothing has punched through.
That is why hail damage is so easy to miss and so easy to argue about. The roof does not leak. It just lost the sunscreen protecting it, and the asphalt now ages far faster than it should. A roof that had fifteen years left might have four. That loss of remaining life is what insurance is paying for, not a hole.
It is also why you cannot judge a hail claim by whether water is coming in. Most valid hail claims are on roofs that are completely dry.
Start on the ground, not the roof
Do not get on your roof. It is the single most dangerous thing a homeowner does after a storm, and you do not need to — hail big enough to damage shingles leaves evidence at eye level first.
Walk the whole property and look at the soft metal and soft surfaces:
| Where to look | What hail leaves behind |
|---|---|
| Gutters and downspouts | Dents in the rounded face, worst on the side facing the storm |
| Window and door screens | Tears, or a dished, stretched look |
| Air conditioner condenser | Dimples across the aluminum fins on the top and one side |
| Roof vents, turbines, flashing | Round dents on the caps and collars |
| Mailbox, garage door, siding | Dents and chipped paint, especially on one elevation |
| Wooden deck rails and fence caps | Small round bright spots where paint or stain was chipped off |
| Downspout outlets | A fresh pile of granules that was not there last month |
The AC unit is the single best indicator on most properties. It is a large sheet of very soft aluminum, it sits in the open, and nothing else in a normal yard dents it.
If none of these show anything, it is unlikely your shingles took a beating the metal escaped. If several do, and the dents concentrate on one side of the house, you have a real reason to look further.
What hail damage looks like on asphalt shingles
If someone does get up there — a contractor, an adjuster, or you looking at their photos — this is what a genuine hit looks like:
- A dark spot where granules are gone and the black asphalt shows through
- Roughly circular, though not perfectly round
- Random in size and placement, because hail falls randomly
- Soft or springy when pressed, like the skin of an overripe fruit — this is the fractured mat, and it is the single most reliable test
- Sometimes shiny, where the asphalt has been exposed and compressed
- No repeating pattern and no alignment with the shingle edges
Fresh damage looks noticeably brighter than old damage. Newly exposed asphalt is dark and clean; after a season in the sun it weathers and starts to look like ordinary wear. That difference is one of the first things an experienced adjuster reads.
What it looks like on other roof types
Not every roof is asphalt, and the evidence changes:
- Metal roofing and metal panels. Hail leaves clean dents. It rarely causes a leak, which is exactly why many policies carry a cosmetic damage exclusion for metal — worth checking your policy before you assume dents are covered.
- Wood shakes. Look for splits with sharp, unweathered edges, often with an impact mark at one end. A split with gray, rounded, weathered edges is old.
- Tile and slate. Hail leaves chips, cracks and corner breaks. Damage tends to be dramatic but localized, and a partial repair is more common than a full replacement.
- Flat and low-slope membranes. Look for circular fractures or "starring" in the membrane, and dents in the metal edge details. This usually needs a professional to assess.
What is NOT hail damage
This is the part nobody at your door will tell you, and it is the part that gets claims denied:
| What you see | What it usually is |
|---|---|
| Small raised bumps that pop open into craters | Blistering — moisture escaping the shingle, not impact |
| Granule loss in straight lines or along edges | Foot traffic, a manufacturing pattern, or normal aging |
| Cracking in a regular, repeating pattern | Thermal splitting from heat cycling |
| Scuffs, scrapes, gouges | Mechanical marks from a ladder, a branch, or a past repair |
| Heavy wear on the south-facing slope only | Sun exposure |
| Curling, cupping or clawing edges | Age, or an underventilated attic |
Blistering is the one that catches people out. It is extremely common, it looks convincingly like hail to an untrained eye, and any adjuster recognizes it instantly. A roof full of blisters does not just fail on those spots — it makes the adjuster skeptical about everything else on the roof, because it suggests a claim filed on a worn-out roof.
A roof can be genuinely old and finished without a single hailstone ever touching it. Insurance covers sudden accidental damage, not age. That distinction is doing all the work here, and it is worth reading our guide to why roofing claims get denied if you want the full list of ways it goes wrong.
Size matters, and there is a rough threshold
Not all hail damages a roof. Storm reports use everyday objects for size, and here is roughly where the risk sits:
| Reported size | Diameter | Typical effect on an asphalt roof |
|---|---|---|
| Pea | 0.25 in | None |
| Penny | 0.75 in | Unlikely; may mark screens and paint |
| Quarter | 1.00 in | Where shingle damage generally starts |
| Half dollar | 1.25 in | Possible, more likely on older roofs |
| Golf ball | 1.75 in | Common |
| Tennis ball | 2.50 in | Likely, often severe |
| Baseball | 2.75 in | Severe, frequently full replacement |
One inch is also the National Weather Service threshold for calling a thunderstorm severe, which is why so much of the industry treats quarter-size as the line.
Three things move that line:
- Roof age. A brittle twenty-year-old roof fractures at a size a two-year-old roof shrugs off.
- Wind. Hail driven sideways at 60 mph hits harder than hail falling straight down, and it concentrates damage on the windward slopes.
- Impact rating. Class 4 impact-resistant shingles are built to survive a 2-inch steel ball. Many carriers discount premiums for them, and they genuinely change the threshold.
Why one slope is wrecked and the next one is fine
Hail arrives at an angle, pushed by the storm's wind. So it hits the slopes facing into the storm hard and the opposite slopes barely at all.
It is completely normal for the north and west faces of a roof to qualify for replacement and the south and east faces not to. This is the single most common source of homeowner frustration during an inspection, and it is not the adjuster being difficult — it is physics. We cover how that plays out on inspection day in what an insurance adjuster looks for on your roof.
The same logic applies at neighborhood scale. Hail falls in narrow paths, so one block can be destroyed while the next one over is untouched. Your neighbor's new roof is a hint, not evidence about your own.
Your twenty-minute walkthrough
- Write down the storm date. Every policy ties a claim to a specific date of loss, and a claim without one is hard to move forward. If you are not sure, check the radar record before you guess.
- Photograph everything, right now. The dented gutter, the torn screen, the AC fins, the granules in the downspout, the chipped fence cap. Timestamped phone photos are exactly the right kind of evidence, and they are worth more the sooner you take them.
- Take wide shots as well as close-ups. A close-up of a dent proves nothing about which house it is on. Get the whole elevation in frame too.
- Check the radar record for your address. Confirm hail actually reached your area and roughly what size, before you rely on anyone's opinion.
- Look inside. Attic for daylight or damp sheathing, ceilings for new stains.
- Then decide whether to get an inspection, and read how to choose a roofer after a hailstorm before you let anyone on the roof.
Do not let anyone rush you. There is real urgency in a storm claim — most policies require you to report damage promptly — but "sign right now, today only" is a sales tactic, not a deadline.
What to do if you find damage
Finding evidence is not the same as having a claim worth filing. The deductible math, your policy's replacement cost terms and your state's filing deadline all still have a say. Work through do I actually have a hail damage roof claim next — it is the honest version of that decision, including the cases where the right answer is to do nothing.
If you do file, what happens after you file a roof claim walks through the whole sequence, including the second check most homeowners never collect.
Check your own address first
Before you call anyone, find out whether hail actually reached your area and how big it was. Our free hail tracker reads the same NOAA radar record the industry uses, and it takes one address and about ten seconds.
If the radar shows a real storm over your house, you can ask us to pass your details to one vetted local roofer for a free inspection. That is your choice and a separate box — we do not share your name, address or phone with anyone unless you tick it.
