Hail damage on asphalt shingles is famously difficult to identify from the ground. The visible signs — granule loss, scuffed surfaces — can look like normal wear.
Hail damage on asphalt shingles is famously difficult to identify from the ground. The visible signs — granule loss, scuffed surfaces — can look like normal wear. The hidden signs — bruises, fractured fiberglass mat, broken self-seal strips — represent active insurance claims worth thousands. Here's the field inspector method.
Ground-Level Indicators (Without a Ladder)
Before climbing anywhere, look for these from your driveway. If any are present, you almost certainly have roof damage:
- Dents in metal gutters and downspouts — hail hits these surfaces visibly
- Bent AC condenser fins — the metal fins on your outside AC unit are highly hail-sensitive
- Damaged window screens, broken patio furniture, dented mail box
- Shingle granules at the bottom of downspout exits (a fresh pile after the storm)
- Splatter marks on painted surfaces where hail melted onto fascia or siding
- Damaged plants and leaves stripped from the windward side of vegetation
If you see ground-level indicators, do not climb up to inspect. Most homeowner injuries during post-hail inspections happen on the second trip up the ladder. Schedule a free contractor or HAAG-certified inspection instead.
On the Roof (Trained Inspector View)
Field inspectors look for these specific indicators of functional hail damage on asphalt shingles:
| Indicator | What It Looks Like | Severity |
|---|---|---|
| Bruises | Soft, dark round circles 1/2"–2" diameter where granules have been knocked off — feels soft to the touch | HIGH |
| Exposed asphalt mat | Black or dark gray substrate visible through granule loss | HIGH |
| Fractured fiberglass | Visible cracks in the shingle body — diagnostic of impact damage | HIGH |
| Broken self-seal strip | Adhesive line between courses is fractured | MEDIUM |
| Bent ridge cap shingles | Visible deformation on the apex of the roof | HIGH |
| Dented or pierced flashing | Aluminum or galvanized flashing visibly indented | MEDIUM |
| Scuff marks (no damage) | Surface scuffs that don't expose mat — typically not claimable | LOW |
The Test Square Method
Professional inspectors document hail damage using a 10x10 ft test square on each slope. Within each square, they count the number of legitimate hail impacts. The damage threshold for a full replacement claim is typically 8+ impacts per test square per slope. Most insurance scopes use this method.
What to Do If You Suspect Hail Damage
- Document immediately. Photograph hailstones with a coin or ruler for scale. Save weather alerts.
- Schedule a free contractor inspection. Use a GAF Master Elite or HAAG-certified contractor — not the door knocker.
- Get a written scope and photos. Before calling insurance, have a baseline.
- Call your carrier's claim line. File the claim using your documentation.
- Have your contractor attend the adjuster meeting. Most scope disputes happen on the ladder.
Storm chasers exploit hail damage chaos. If you have hail damage, expect 5-15 door knocks in the first two weeks. Use the 12 storm chaser red flags to filter — and never sign a contract during a first door visit.
