Iowa storm damage FAQ
Was there hail in Iowa recently?
The most recent verified severe weather report in Iowa was filed on Sep 5, 2026. Over the last 12 months, NWS spotters logged 625 hail reports across 54 separate hail days in the state.
How big does hail need to be to damage a roof?
Hail around 1 inch (quarter size) and up can bruise or crack asphalt shingles — that's the size adjusters take seriously. The largest verified hail in Iowa in the last 12 months measured 4.5" — softball sized — and the state logged 47 days with 1"+ hail.
How long after a hailstorm can homeowners file a claim?
It depends on the policy and the state, but most homeowner policies allow one to two years from the storm date — some as little as six months. That's why the storms on this page are still live opportunities: the roofer who documents the damage first usually writes the job.
