Hail Damage Roof Inspection Guide: What Hail Damage Actually Looks Like

How to Identify Hail Damage on a Roof Before Filing a Claim

Homestead Roofing owner Tracy Bookman walks an actual hail-damaged roof and shows homeowners exactly how to identify hail damage themselves, from the obvious black bruises to the subtle dimples you can only find by touch.

After a hail storm moves through a neighborhood, the roofing salesmen are not far behind. They canvas streets, knock on doors, and offer free roof inspections. The homeowner who cannot independently verify what they are being told is at a disadvantage. Tracy Bookman believes homeowners should be able to do their own preliminary inspection before ever picking up the phone. He walks an actual hail-damaged roof and narrates what he is seeing in real time, showing both obvious damage and the subtle signs that are easy to miss.

The roof he chose for the demonstration is especially useful because the storm hit with different intensity on different sides. One slope took the brunt of the impact and shows heavy, immediately visible damage. The opposite side has lighter, more subtle damage, the kind a less experienced inspector might miss entirely.

What Hail Damage Actually Looks Like

The most visible sign of hail damage is the black spots that appear scattered across shingles after a significant storm. These are not just discoloration. A hailstone, in this case roughly an inch and a half in diameter, strikes the shingle with enough force to dislodge the protective granules from the asphalt layer beneath. Rain then washes the loosened granules away, exposing a dark asphalt bruise that is visible from the ground if the damage is severe enough.

An insurance adjuster will look for these bruises systematically. The standard method is to chalk out a 10-foot by 10-foot square on each major roof slope and count the number of hail strikes inside it. Most adjusters want to see between eight and twelve identifiable hail hits per test square to consider the damage significant enough to warrant a claim. The threshold varies by insurance company and individual adjuster, but the principle is consistent: the damage has to be distributed across the roof, not concentrated in a few isolated spots.

Why You Need to Be on the Roof, Not Looking at Drone Photos

Tracy Bookman is direct about drone inspections: he does not believe in them for hail damage assessment. A drone photograph taken from several feet above the roof surface will capture large, obvious hail bruises. It will miss the subtle ones. And the subtle ones matter, because on a roof slope that caught the edge of the storm rather than the center, the difference between a claim that is approved and one that is denied can come down to whether the adjuster can find enough hail hits to meet the per-square threshold.

The advantage of being physically on the roof is touch. A hail strike leaves a small dimple or indentation in the shingle, a depression where the stone compressed the asphalt on impact. Tracy Bookman demonstrates by running his finger over suspected damage spots. The dimple confirms that something struck the shingle with force, as opposed to a manufacturing defect or random granule loss. He also demonstrates a simple rub test. Lightly rubbing a suspected hail bruise with a fingertip will cause loose granules to come off if the spot is genuine impact damage. Rubbing the same way on an undamaged section of shingle will not produce granule loss.

Where to Look and Where Not to Bother

Not every hail bruise carries equal weight with an insurance adjuster. Damage in the middle of the shingle is what adjusters consider most significant, because that is where the shingle is most vulnerable to water infiltration if the protective granule layer is compromised. Damage at the very edge of a shingle or right at the bottom reveal is less likely to influence the adjuster's determination.

Ridge shingles often show extensive hail damage because they sit at the highest point of the roof and take direct hits at a flatter angle. Tracy Bookman points out ridge damage on the demonstration roof that is heavy and immediately obvious. But ridge shingles can be replaced independently without touching the field shingles, so adjusters typically do not count ridge damage toward the per-square threshold used to determine whether the entire roof needs replacement. The field shingles, everything that is not ridge, hip, or starter shingles, are what the adjuster is evaluating.

Metal fixtures on the roof provide supporting evidence. Furnace vent caps, plumbing vent covers, attic power vent housings, anything metal on the roof surface, will show denting from hail that is large enough to damage shingles. These dents do not usually affect how the fixtures function, but they serve as objective proof that hail of damaging size struck the roof. Tracy Bookman calls this ammunition for the homeowner: evidence that supports the shingle damage findings, especially on slopes where the granule loss is harder to see.

How to Do Your Own Pre-Inspection

Tracy Bookman demonstrates on the lightly damaged slope by chalking out two separate 10-foot by 10-foot squares and marking every identifiable hail bruise inside them with a small dot. The purpose is to know what is there before anyone else climbs onto the roof, to have your own count, your own photos, and your own assessment of whether the damage meets the threshold. If you find 10 to 12 identifiable hail bruises in a test square and you can replicate that across multiple roof slopes, you have a strong basis for filing a claim. If you struggle to find more than a few isolated spots per square, the damage may not meet the adjuster's threshold.

For homeowners who are not comfortable getting on the roof, the next best option is to hire a roofing contractor who physically walks the roof and shows you photos of what they find, with test squares marked. The key distinction is whether the inspection is done from the roof surface or from a distance, and whether the findings are demonstrated with specific marked evidence rather than vague assurances.

Frequently Asked Questions

How many hail hits per square does an adjuster need to approve a claim?

Most insurance adjusters want to see between eight and twelve identifiable hail hits inside a 10-foot by 10-foot test square on each major roof slope. The exact threshold varies by insurance company and adjuster. The damage must be distributed across the roof, not concentrated in isolated spots.

Can you spot hail damage from the ground?

Severe hail damage is visible from the ground as black spots on shingles where granules have been knocked off. Lighter damage requires being on the roof to feel for dimples and perform the rub test. A drone cannot reliably detect subtle hail damage the way a physical inspection can.

Do insurance adjusters count ridge cap damage?

Typically no. Ridge shingles can be replaced independently without touching the field shingles, so most adjusters do not count ridge damage toward the per-square threshold. The field shingles, everything that is not ridge, hip, or starter shingles, are what the adjuster evaluates for full roof replacement.

How can I tell the difference between hail damage and normal wear?

Tracy Bookman demonstrates a rub test: lightly rub a suspected hail bruise with your fingertip. If loose granules come off, it is impact damage. Rub the same way on an undamaged section of shingle and no granules should come loose. A hail strike also leaves a small dimple you can feel, which does not occur with normal granule loss or manufacturing defects.
