Columbia, Missouri experienced golf ball-sized (1.75") hail on June 1, 2026.

Damage assessment

Golf ball-sized hail at 1.75" poses a moderate threat to standard architectural asphalt shingles. At this magnitude, functional damage is likely on roofs over 10-15 years old, including granule loss, exposed mat, and potential penetration of aging shingles. Newer roofs may experience primarily cosmetic damage with significant granule displacement. Class 4 impact-resistant shingles would substantially reduce damage risk at this hail size.

Historical context

This event ranks #22 of 51 recorded hail events in Boone County's 10-year record. The county's largest recorded event measured 3" on March 31, 2023. June represents typical seasonal activity with 6 historical events, well below March's peak of 24 events.

Storm system

The Columbia hailstorm was part of a broader regional severe weather outbreak affecting multiple counties across Missouri and Kansas, with hail sizes ranging from marble to golf ball across the region.

Contractor guidance

Columbia's moderate contractor market currently shows 2-4 week backlogs. Missouri statute RSMo § 407.725 explicitly prohibits contractors from offering to pay deductibles or negotiate insurance claims. Homeowners should verify contractors carry proper insurance, maintain local business presence, and hold required municipal licenses. Columbia's limited post-storm capacity often draws out-of-area contractors, increasing storm chaser exposure.

Permits & building code

At 1.75" magnitude, roof repair is more likely than full replacement for most properties. Contractors typically handle permit applications, with costs ranging $150-350 and inspections required. While Class 4 shingles aren't mandated, the 10-20% insurance discount combined with superior hail resistance makes them worth considering during any roof work.
