Golf ball-sized hail detected near Iowa City, IA on June 10, 2026
Hail was detected at a radar-indicated point within the Iowa City 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 (1.75 inch) hail typically causes functional damage to standard architectural asphalt shingles, including exposed mat, cracked shingles, and granule loss that compromises the roof's weatherproofing capacity. Roofs over 10-15 years old are particularly vulnerable to impact damage at this magnitude, while newer installations may show less severe but still measurable impact marks. Class 4 impact-resistant shingles would likely sustain cosmetic damage but maintain better structural integrity than standard materials.
With a typical deductible of $7,000 on a $350,000 home and repair costs averaging $6,243 for a 2,000 square foot roof, this event falls near the deductible threshold where professional assessment becomes critical. Deductibles vary by individual policy terms, and a professional inspection can help determine whether damage is cosmetic and manageable out of pocket, or functional enough to warrant insurance discussion. Homeowners should check their policy declarations page for specific claim filing deadlines, as this information was not available in the initial damage assessment.
At these numbers, you're better off repairing out of pocket — the typical repair cost falls below your deductible. Filing a claim likely isn't worth it unless a full inspection reveals significantly more damage.

Contractor guidance
Local contractor availability shows a moderate backlog of 2-4 weeks, with moderate storm chaser risk as out-of-area contractors typically arrive following regional hail events. Iowa Code §§ 103A.71 and 515.137A prohibit contractors from waiving or absorbing insurance deductibles, with violations subject to enforcement under the Iowa Consumer Fraud Act. Before hiring, verify general liability insurance, workers' compensation coverage, and ensure contracts include required Iowa consumer protection disclosures as mandated by state law. Iowa does not require separate state roofing licenses, but residential contractors must comply with specific contract requirements for insurance-related work.
Permits & building code
At 1.75 inches, roof repair is more likely than full replacement, requiring contractor-pulled permits costing $150-350 and mandatory inspections. While Class 4 shingles are not required by local code, the 10-20% insurance discount makes them worth considering during repair, especially given Iowa City's exposure to recurring severe weather events.
