Filing a roof or car hail claim?

Insurers ask for the date of loss. The dates on this page are when hail was reported near Custer County; hail can hit one street and miss the next, so a report is not proof of damage at your address. A licensed roofer or your insurance adjuster can inspect the roof. Many policies set a time limit for filing a claim — check yours.

Data: NOAA NCEI Storm Events Database (final records through Jun 30, 2026) and National Weather Service Local Storm Reports (preliminary, since then).
