How hail affects asphalt shingles
Asphalt shingles rely on mineral granules to protect the underlying asphalt layer from sunlight and weather exposure. When hailstones strike the roof surface, those granules can be knocked loose or displaced.
- Small hail can gradually loosen protective granules.
- Larger hailstones may create dents or bruises in the shingle surface.
- Repeated storms can accelerate granule loss and shorten roof lifespan.
Damage from hail is not always easy to see from the ground, which is why roof inspections are often requested after severe storms.
Why Oklahoma roofs often experience hail damage
Oklahoma sits in one of the most active hail corridors in North America. During spring and early summer, supercell thunderstorms frequently produce hail capable of damaging roofing materials.
- Fast-moving storm cells can produce high-velocity hail impacts.
- Wind-driven hail may strike exposed roof slopes directly.
- Older roofs may be more vulnerable if granules have already worn down.
Do not climb onto the roof after a hailstorm
After a storm, many homeowners are tempted to climb onto the roof to look for damage. However, climbing onto a roof can be dangerous, especially when shingles are wet or loose after hail impact.
Roof slopes can be steep and slippery, and falls from roofs are a common source of home-related injuries. For this reason, safety experts generally recommend that homeowners avoid climbing onto the roof themselves.
If damage is suspected, many homeowners choose to request a roof inspection instead of attempting to inspect the roof on their own.
Signs of possible hail damage from the ground
- Dents in gutters or metal flashing
- Granule buildup near downspouts
- Chipped paint or dents on siding and window trim
- Shingle fragments in the yard after storms
These signs can indicate that hail affected the roof, even when damage cannot be seen from ground level.
