Golf ball-sized hail detected near Columbia, MO on July 10, 2026
Hail was detected at a radar-indicated point within the Columbia monitoring area. Actual impact can vary by neighborhood, so nearby homes should use this as a signal to check roofs, gutters, siding, and vehicles.
Damage assessment
The radar-confirmed strike landed approximately 8 miles northwest of downtown Columbia, with one hail report logged across Boone County that day. At 2 inches, golf ball-sized hail is large enough to cause functional damage to standard architectural asphalt shingles — not just granule loss, but denting, cracking, and compromised mat integrity that shortens roof lifespan. Shingles already past 15 years are at greatest risk; newer installations may show impact marks without immediate leaking. The same-day event in Buchanan County registered 2.5 inches, suggesting a broader system moved through the region with variable intensity.
On a home at Columbia's median value of $268,300, a 2% deductible works out to roughly $5,366 out of pocket before insurance pays a dollar. Typical repair cost for a 2,000 square foot roof runs $5,969, with a range of $4,883 to $7,054 depending on pitch, access, and material pricing in the Columbia market. Get a professional inspection before making any insurance decisions.
At these numbers, the typical repair cost exceeds a standard 2% deductible. Contact your insurer — damage at this level is likely worth filing before you pay out of pocket.

Historical context
This event ranks 13th of 51 recorded hail events of 1 inch or larger in Boone County over the past ten years — a mid-tier storm, not the worst the area has seen. The county's largest recorded event reached 3 inches on March 31, 2023, which is well above today's magnitude. July historically produces about four such events per decade in this county, putting this storm squarely in line with seasonal norms.
Storm system
The same-day reports from Johnson County, Kansas and Buchanan County, Missouri confirm this was part of a broader regional system rather than an isolated cell, with Buchanan County recording the largest hail at 2.5 inches.
Contractor guidance
Local contractor data shows current backlogs running 2 to 4 weeks in the Columbia market, which is moderate but can stretch if additional storms follow. The intake assessment rates storm chaser risk as moderate — Columbia draws out-of-area contractors after regional events, and that pool varies widely in quality. Missouri does not issue a state roofing license, so RSMo § 407.725 and the Home Services Contracts Act (RSMo § 407.025) set the baseline rules for contractor conduct tied to insurance claims. Before signing anything, verify the contractor carries general liability and workers' compensation insurance, has a verifiable local business address, and holds any applicable municipal license — and know that under RSMo § 407.725, any contractor who offers to cover or rebate your deductible is breaking Missouri law.
Permits & building code
At 2 inches, whether a roof needs repair or full replacement depends on shingle age and the inspector's findings — both outcomes are realistic. Boone County requires a permit for roofing work; the contractor pulls it, it costs $150 to $350, and an inspection is required before the job closes. Class 4 impact-resistant shingles qualify for a 10–20% discount with most Missouri insurers.
