How to Tell If Your Roof Has Hail Damage: Signs by Material

Stay off the roof — hail-loosened granules make slopes slick, and most storm evidence shows up at ground level anyway. Walk the perimeter within a few days and check soft metals and painted surfaces.

The most reliable ground-level indicators are:

• Dents in gutters, downspouts, and gutter guards
• Dings or flattened fins on the AC condenser
• Torn or dimpled window screens and chipped window trim
• Dark splatter marks on driveways, decks, or electric meters
• Shredded leaves or stripped plants on one side of the house
• Piles of shingle granules at downspout outlets

Several of these together mean the roof almost certainly took the same stones, and one-sided damage tells an adjuster which slopes faced the storm.

On asphalt shingles, hail damage shows up as random, dark, roughly circular bruises where impacts knocked granules away and exposed the mat underneath. Fresh hits look shiny or black with sharp edges; ordinary wear looks gray with feathered edges. A true hail bruise often feels soft to a gentle press, like a bruise on an apple, because the impact fractured the fiberglass mat below.

Pattern matters as much as the marks. Hail scatters hits randomly across a slope, so neat lines or repeating spots usually point to something else. Adjusters also check collateral evidence first: dents in ridge vents, pipe boots, and flashing confirm hail actually reached the roof.

Metal roofs dent, which makes hail damage easy to see but sometimes harder to collect on. Many policies carry a cosmetic damage exclusion, so insurers pay only when the damage is functional — a fractured panel, a disengaged seam or fastener, or coating damage that lets water through.

Wood shingles and shakes split on impact. A fresh hail split has sharp edges and an unweathered, orange-brown interior, while old splits are gray inside — a distinction Haag Engineering field researchers use to date the damage (Marshall et al., 2002).

Tile, slate, and concrete roofs chip, crack, or shatter at the impact point rather than bruise. Concrete tile is far tougher than asphalt, so broken tiles usually mean very large stones fell — or that foot traffic, not hail, did the breaking.

Hail around 1 inch in diameter — quarter size, the National Weather Service threshold for a severe thunderstorm — is where functional damage to common asphalt shingles begins. Field surveys by Haag Engineering researchers (Marshall, Herzog, Morrison & Smith, 2002) documented where damage starts for each material:

Age moves these thresholds down. In the same study, 11-year-old organic-mat 3-tab shingles were damaged half the time by 1-inch ice stones, while new S-shaped concrete tiles needed 2-inch stones before damage appeared.

Blistering is heat damage from inside the shingle, not impact damage: blisters have raised, hollow edges and no bruise in the mat underneath. Craze cracking from thermal aging runs in patterned lines, while hail scatters randomly. Uniform granule loss with soft, feathered edges is ordinary weathering, and circular scuffs with smeared granules usually mean foot traffic, not hailstones.

The distinction decides claims. Wind and hail is the most frequent homeowners claim — 2.8 claims per 100 insured homes per year, averaging $14,747 per claim from 2019 to 2023, per the Insurance Information Institute (2026) — so adjusters are trained to separate storm damage from wear and tear. Claiming aging as hail is one of the fastest routes to a denied roof claim.

Document first, decide second. Write down the storm date, photograph every ground-level clue plus any roof damage you can shoot safely, and keep the date stamps — hail evidence weathers fast.

Then get a professional inspection before calling your insurer. A reputable local roofer or independent inspector can confirm whether the damage crosses the functional threshold adjusters use — knowing how to tell if your roof has hail damage from the ground triggers that inspection; it does not replace it. Be wary of door-knocking storm chasers.

The stakes are real: State Farm alone paid more than $5.6 billion in hail claims in 2025, per its April 2026 claims report, and NOAA Storm Prediction Center data compiled by the Insurance Information Institute (2026) counted 5,432 hail events that year.
