Montana storm damage FAQ
Was there hail in Montana recently?
The most recent verified severe weather report in Montana was filed on Sep 14, 2026. Over the last 12 months, NWS spotters logged 155 hail reports across 40 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 Montana in the last 12 months measured 3.25" — baseball sized — and the state logged 26 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.
