South Dakota storm damage FAQ
Was there hail in South Dakota recently?

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 South Dakota in the last 12 months measured 4.5" — softball sized — and the state logged 43 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.
