Golf ball-sized hail detected near Columbia, MO on June 11, 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
Golf ball-sized hail poses a moderate threat to Columbia's dominant architectural asphalt shingles. At 2 inches, this magnitude typically causes functional damage including granule loss, exposed mat, and potential seal failures on roofs over 10-15 years old. Newer roofs may experience primarily cosmetic granule loss, while aging shingles face increased risk of cracking and punctures. Class 4 impact-resistant shingles would significantly reduce damage potential at this hail size.
With a typical 2% deductible on Columbia's median home value of $268,300, homeowners face a $5,366 deductible against estimated repair costs of $5,874 for a 2,000 square foot roof. Deductibles vary by individual policy terms, and a professional inspection can help determine whether damage is cosmetic, manageable out of pocket, or significant enough to warrant an insurance discussion. Homeowners should check their policy declarations page for specific filing deadlines.
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 #13 of 51 recorded hail events in the 10-year county record, placing it in the upper tier of magnitude. The largest recorded event remains 3-inch hail on March 31, 2023.

Storm system
This event was part of a broader regional system that produced golf ball-sized hail in Peoria, Illinois, and half dollar-sized hail in Sangamon, Illinois and Jackson, Missouri the same day.
Contractor guidance
Columbia's moderate contractor market currently shows 2-4 week backlogs, with moderate storm chaser risk following regional events. RSMo § 407.725 explicitly prohibits contractors from advertising deductible payments or rebates as sales inducements and bars them from negotiating insurance claims. Homeowners should verify that contractors carry general liability and workers' compensation insurance, maintain a verifiable local business presence, and hold applicable municipal licenses. Missouri does not require state-level roofing contractor licensing, increasing the importance of due diligence.
Permits & building code
At golf ball magnitude, repair is more likely than full replacement for most Columbia roofs. Contractors typically handle permit applications, with costs ranging $150-350 and inspections required. Given the 10-20% insurance discount for Class 4 shingles and their superior hail resistance, homeowners facing replacement should strongly consider the upgrade.
