About this storm

How big was the hail in Colorado on Thursday, May 21, 2026?

The largest verified hail report that day measured 4.5" — softball sized. NWS spotters filed 13 hail reports across 11 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 58 days ago, so the filing window is open for most policies.
