How to Identify Hail Damage on a Roof

What hail damage looks like

Genuine hail impacts on asphalt shingles share a few signatures:

• Random distribution — real hail strikes have no pattern. Damage in straight lines or only along one edge usually points to wear, foot traffic, or manufacturing defects instead.
• Granule loss — the protective mineral granules are knocked away, exposing the dark asphalt mat. You may see granules collected in gutters.
• Soft bruises — a hail hit feels soft or springy when pressed, similar to a bruise on fruit, because the mat beneath has been fractured.
• Shiny or fresh-looking dents — recent impacts often look cleaner and darker than the weathered shingle around them.

Check the easy indicators first

You don't need to climb on the roof to gather strong clues. Soft metal surfaces dent under hail and are visible from the ground or a ladder:

• Gutters and downspouts — look for dimples and dents.
• Metal vents, flashing, and valleys — random pockmarks indicate impacts.
• Air-conditioner condenser fins — these bend easily and often record a storm.
• Window screens, wraps, and fence caps — softer materials show strikes clearly.

Why a professional inspection matters

Much hail damage is functional rather than obvious — fractured mats and bruising can compromise a shingle's water-shedding ability and shorten its life without any visible hole. This kind of damage is hard to spot from the ground and easy to misjudge.
