Golf ball-sized hail detected near Ames, IA on July 2, 2026
Hail was detected at a radar-indicated point within the Ames 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 was located approximately 19 miles northeast of downtown Ames, with one hail report logged in Story County that day. At 2.25 inches, architectural asphalt shingles are at real risk of functional damage — granule loss, cracked tabs, and compromised mat integrity — not just cosmetic bruising. Shingles older than 15 years are more vulnerable; newer roofs may show damage but retain waterproofing function. This event ranks 11th by magnitude in the county's 10-year record, so it is not an outlier — but it is large enough to warrant a physical inspection.
On a $350,000 home with a 2% wind/hail deductible, your out-of-pocket threshold is $7,000 before insurance pays anything. Typical repair cost for a 2,000 square foot roof runs $6,344, with a range of $5,191 to $7,497. Get a professional inspection before making any insurance decisions.
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 data shows current backlogs of 1 to 2 weeks in this market, and storm chaser risk is assessed as low. Iowa Code § 103A.71 governs contractors performing insurance-related storm repairs — it requires specific written disclosures in the contract, not just a handshake agreement. Iowa does not issue a separate state roofing license, so proof of general liability, workers' comp, and the § 103A.71 disclosures are what you verify before signing anything.
Permits & building code
At 2.25 inches, full replacement is plausible depending on roof age and shingle condition, though repair is possible on newer installations. The contractor pulls the permit in Ames, inspections are required, and permit costs typically run $100 to $250. Class 4 impact-resistant shingles qualify for a 10–20% discount with most Iowa insurers.
