Can Small Hail Actually Damage a Roof?

Small hail, from pea to marble size, may not punch through a roof, but it can still cause harm. The impact can knock the protective mineral granules off asphalt shingles, exposing the underlying mat to sunlight and weather. That accelerates aging and makes the shingles brittle.

On metal roofs, small hail can dent softer metals like aluminum or leave scratches that become rust points. On flat roofs, hail can dent or crack the membrane, especially if it's older or already weakened. The damage isn't always visible from the ground, so a close look is important.

• Bruised or granule-lost shingles
• Dents or scratches on metal panels
• Cracked or punctured flat roof membrane
• Clogged gutters from hail accumulation
• Loosened flashing or sealant
• Granules in downspouts or on the ground

Look for circular bruises on asphalt shingles, which feel soft or spongy when you press on them. You might see the fiberglass mat exposed where granules have been knocked away. On metal roofs, check for small dents or scratches that expose bare metal.

Inside your home, watch for water stains on ceilings or walls, especially in the days after a storm. Hail damage can take a while to become a leak, as water slowly works through weakened spots. If you notice granules in your gutters or on the ground, that's a clue your roof took a hit.

Regular roof maintenance can make your roof more resilient to hail. Keep gutters clear so hail and water drain quickly. Trim overhanging branches that could break and hit the roof during a storm. If your roof is nearing the end of its lifespan, consider replacement with impact-resistant materials.

After any hailstorm, do a quick visual check from the ground and from windows. If you can safely access the roof, look for loose shingles or dents. Document any damage with photos for your records. Policies vary, and your insurer decides what is covered.
