If you live in North Georgia, hail damage is the single most common reason your roof gets replaced. Storm systems regularly drop golf-ball to baseball-sized hail across Forsyth, Hall, Gwinnett, Fulton, Jackson, and Barrow counties. The April 10, 2025 storm alone produced documented 3-inch hail in parts of the metro area. The August 30, 2024 event hit Roswell and Alpharetta with half-dollar-sized stones.
Most homeowners never realize they have damage. They look up at their roof, see no missing shingles, and assume they're fine. Then a year later they have a leak, the storm filing window has closed, and they're paying for a roof out of pocket.
This guide explains exactly what hail damage looks like, where to find it, and how to confirm it without climbing on your roof.
What hail does to a roof shingle
An asphalt shingle is built in layers: a fiberglass mat, asphalt coating, and ceramic granules embedded on the surface. The granules are what give the shingle its color and — more importantly — what protect the asphalt from UV light. When hail strikes a shingle, it can do four things:
- Knock granules loose in a circular impact pattern, exposing the asphalt mat below. This is the most common form of hail damage.
- Bruise the shingle — fracture the fiberglass mat without breaking the surface. The shingle stays in place but its waterproof barrier is compromised.
- Crack or split the shingle outright when impact is severe.
- Dislodge the shingle from its sealant strip, allowing wind uplift and water intrusion.
The first two — granule loss and bruising — are the ones that homeowners almost always miss because they don't show up clearly from the ground.
The five visible signs of hail damage
1. Circular granule-loss spots on shingles
This is the classic hail damage signature. Look for round dark spots, roughly the size of a dime to a quarter, distributed randomly across roof slopes. The center of each spot will look black or dark gray (exposed asphalt) compared to the surrounding shingle color.
Granule-loss spots are the most reliable indicator that hail of damaging size struck your roof. They form in patterns that are random and uniform across slopes — different from the predictable wear patterns caused by sun and water flow.
2. Bruising you can feel
Bruising is harder to see but easy to feel. When you (or a roofer) press a thumb against a hail-bruised shingle, the spot feels soft or rubbery — different from the firm, gritty surface of an undamaged shingle. Bruising means the shingle's mat has been fractured even though the surface looks mostly intact. These shingles will fail within months to years and need to be replaced.
3. Damaged metal roof components
Hail damage to softer materials around your roof is the easiest sign to spot from the ground. Look for:
- Dents in roof vents — pipe boots, exhaust vents, attic vents, and ridge caps all dent under hail impact
- Dents or scratches on flashings — chimney flashings, drip edge, valley flashing
- Damaged gutters and downspouts — dimples, dents, or paint chips on aluminum gutters
- Bent or damaged gutter screens or leaf guards
4. Damage to non-roof exterior surfaces
If hail damaged your AC unit, fence, or vehicles, your roof was hit harder than any of those (because the roof is the highest point). Look for:
- Dents in the aluminum fins of outdoor AC condenser units
- Splatter marks on wood decks, painted surfaces, or fences
- Pock marks on car hoods or trunks
- Damaged window screens, especially mesh tears
- Cracked vinyl siding (especially older brittle siding)
If anything else around your house was hit by hail, your roof was hit too. The roof is the highest, most exposed surface — it always takes the worst of any hail event. We've never inspected a hail-damaged AC unit and found the roof above it untouched.
5. Granule accumulation in gutters and downspouts
After a hail or wind storm, check your gutters and downspouts for granule buildup. A handful of granules is normal — they shed throughout the shingle's life. A heavy layer of granules at the base of downspouts is a strong indicator that significant granule loss occurred during a recent storm event.
What hail damage isn't (common false positives)
Not every dark spot on a shingle is hail damage. Here's what we often see homeowners mistake for hail:
- Algae streaks: long dark vertical streaks running down a slope are usually algae growth (Gloeocapsa magma), not hail. Algae is cosmetic and not insurance-covered.
- Foot traffic marks: dark scuff marks in straight lines are usually from someone walking the roof, not hail impact.
- Blistering: raised bubbles on shingles are usually heat-related blistering, not hail. These look raised, not depressed.
- Manufacturing defects: uniform color variations across multiple shingles in a single batch are often manufacturing flaws, not storm damage.
- Wear and tear from age: uniform granule thinning across all slopes, especially on roofs over 15 years old, is age-related.
An experienced roofer can distinguish these from real hail damage in 60 seconds.
Confirming hail damage without climbing the roof
You don't need to walk your own roof to know if you have damage. Here are three safer ways to check:
- Walk your property — look for hail dents on AC units, fences, gutters, and downspouts. If you find them, your roof has damage.
- Check the NWS storm event database at weather.gov/ffc/past_events. If a hail event of one inch or larger was reported within 5 miles of your home in the past 12 months, your roof should be inspected.
- Get a free roof inspection from a qualified contractor. We use a combination of physical walks and drone photography to document damage. Inspections take 30-45 minutes and cost nothing.
What to do if you find hail damage
Once you've confirmed or strongly suspect hail damage:
- Document it. Take photos of any visible damage from the ground, plus dents on AC units, fences, and gutters. These corroborate roof damage to your adjuster.
- Get a written contractor inspection with photos and storm-date documentation. We provide this for free.
- File your claim with the carrier. Read our claim filing guide for the full process.
- Have your contractor present at the adjuster inspection — this is when scope is decided, and a qualified roofer catches damage adjusters miss.

Frequently asked questions
How big does hail need to be to damage a roof? +
Hail as small as one inch (about the size of a quarter) can cause shingle damage. Hail at 1.5 inches and larger almost always causes damage. The North Georgia hail event on April 10, 2025 produced golf-ball to 3-inch hail across multiple counties — homes in those areas almost certainly have damage even if it isn't visible from the ground.
Can hail damage be invisible from the ground? +
Yes — and this is the most common pattern. Hail damage often shows as small circular spots where granules have been knocked loose, which is invisible from the driveway. Bruising and lifted shingles also can't be seen from below. The only reliable way to assess hail damage is to walk the roof or use a drone inspection. Both should be free from a qualified roofer.
How long do I have to file a hail damage claim in Georgia? +
Most Georgia homeowner insurance policies require filing within one year of the storm event. After 12 months, claims are typically denied even if damage is real. The April 10, 2025 hail event creates a filing window through April 2026 — so North Georgia homeowners affected by that storm should act now if they haven't already.
What does hail damage look like vs normal wear and tear? +
Hail damage is typically circular, sharp-edged, and uniformly distributed across all roof slopes facing the storm. Wear and tear is usually concentrated in high-traffic areas (around chimneys, valleys), shows as gradual granule thinning rather than circular spots, and is more pronounced on south- or west-facing slopes that take more sun. We can show you side-by-side examples during an inspection.
Will a roofer charge for a hail damage inspection? +
Reputable contractors in North Georgia, including Bishop JD Roofing, offer free hail-damage inspections. There's no obligation, no pressure, and no fee — even if we find no damage. Be cautious of any contractor who charges for an initial storm-damage inspection.
