About this storm

How big was the hail in South Dakota on Tuesday, August 11, 2026?

The largest verified hail report that day measured 4.5" — softball sized. NWS spotters filed 65 hail reports across 60 towns.

Is that big enough to damage a roof?

Hail around 1" (quarter size) and up can bruise or crack asphalt shingles — that's the threshold insurance adjusters take seriously. Damage is often invisible from the ground, which is why an inspection matters even when the roof "looks fine."

How long do homeowners have to file a claim for this storm?

Most homeowner policies allow one to two years from the storm date — some as little as six months. This storm was 15 days ago, so the filing window is open for most policies.

How do I check if a specific address was hit?

Run a free roof report on Rooftops AI: type the address and you get the roof's measurements plus its verified hail history — every NWS-logged report near that exact property, with dates, sizes, and distances.
