After a hail storm: what to do about your roof

1. Look from the ground first: dented gutters, downspouts, vents and AC fins are the easiest signs hail was big enough to hurt shingles. Don't climb a wet or steep roof.
2. Get an inspection. The inspection guide covers what bruising and granule loss look like and what an inspection costs.
3. Check your deadline and deductible. Many policies set a time limit to file and some use a percentage wind/hail deductible; the claim calculator shows what you'd net.
4. Price it yourself before the adjuster does: hail damage repair vs replacement costs.

Hail around 1 inch and larger is generally the range where asphalt shingle damage becomes likely; smaller hail can still damage older or brittle roofs. A report near you is a reason to inspect, not proof of damage.

Other states: Texas, Kansas, Illinois, Nebraska, Minnesota, South Dakota, Missouri, Wisconsin, Iowa, Colorado, Ohio, Indiana, or the national hail report map list.

Sources and how this updates

• NOAA National Centers for Environmental Information, Storm Events Database, hail events 2024–2026 (finalized data through Jul 31, 2026; bulk files: StormEvents_details-ftp_v1.0_d2024_c20260728.csv.gz, StormEvents_details-ftp_v1.0_d2025_c20260819.csv.gz, StormEvents_details-ftp_v1.0_d2026_c20261026.csv.gz).
• NOAA Storm Prediction Center, daily storm reports (preliminary hail reports, 2026-07-01 through 2026-10-29). SPC days run 12Z to 12Z, so a late-night storm can appear under the prior date.
• Hail size comparisons: NOAA National Weather Service, SKYWARN hail size chart.

Data refreshed Oct 30, 2026. Preliminary SPC reports can be duplicated or revised; NCEI replaces them with quality-controlled records about three months later. A report marks where a spotter or station saw hail, not every roof that was hit.
