Hail Damage on Roofs: What It Looks Like and How to Find It

On asphalt shingles, hail impact often leaves a dark, bruised spot where the granules have been knocked off. You may also see cracks that look like a starburst or a small depression. These weak spots let water seep under the shingle and into the roof deck.

Check for granule loss in your gutters and downspouts. A heavy buildup of black or gray granules after a storm is a strong clue. Also look at the base of downspouts for piles of granules on the ground. Missing granules expose the asphalt layer to sun and rain, speeding up wear.

• Dark, soft spots on shingles that feel spongy
• Cracks radiating from a central impact point
• Shiny or exposed asphalt where granules are gone
• Dents on metal roof vents, flashing, or gutters
• Granule buildup in gutters or at downspout bases

Asphalt shingles show bruising or granule loss, as described above. Wood shakes may split or crack along the grain. Metal roofs can dent, and the protective coating may scratch, leading to rust over time. Tile roofs might crack or chip, especially at the edges.

Each material fails differently, so know what to look for on your roof. For example, on a flat roof with a membrane, hail can cause punctures or tears. These are harder to spot from the ground and may require a closer look by a professional.

Hail damage can lead to leaks, so act quickly to protect your home. If you see water stains on ceilings or walls, or if you notice a damp attic, address it soon. Temporary measures like tarping a damaged area can help until repairs are made.

Check your attic after a storm for signs of moisture or daylight coming through the roof. If you find any, place a bucket to catch drips and move valuables away. The pros can dry out the area and help mitigate water damage before mold becomes a problem.

• Look for water stains on ceilings or walls
• Check the attic for damp insulation or wet spots
• Move furniture away from any leaking area
• Use a tarp to cover a small damaged section if safe
