What to check after a storm
Roof damage costs
Missing or creased shingles, dents, and bare spots where granules came off. Roof repair after hail is the most common claim.
Gutters damage costs
Dents in gutters and downspouts, and granules collecting at the downspout outlets.
Siding damage costs
Cracks, chips, and holes in vinyl, fiber cement, and trim, usually on the side the storm came from.
Timing matters. Many insurance policies set a deadline for reporting storm damage, and it varies by insurer and state. Check your policy before assuming it's too late.
Protect your things from a roof leak
Stay off the roof, especially when it's wet or damaged. A licensed roofer should inspect it.

About this data
Storm reports come from the National Weather Service, published in NOAA's Storm Events Database, through June 30, 2026. NOAA publishes them about 3 to 4 months after each storm. A report means hail or wind was observed nearby, not that any particular home was damaged. City figures count reports within 10 miles of the city center. DamageScore is not affiliated with NOAA or the National Weather Service. How we use this data
AI estimate, not an inspection. This score comes from a photo, and a photo can't show everything. Whatever the score, always have a licensed professional inspect the damage before you make repair, safety, or insurance decisions. Cost ranges are typical figures for your area, not quotes. We never tell you whether to file an insurance claim.
