Golf ball-sized hail detected near Sioux City, IA on June 30, 2026
Hail was detected at a radar-indicated point within the Sioux 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
The radar-indicated strike fell approximately 4 miles southeast of downtown Sioux City, with one hail report logged in Woodbury County that day. At 1.75 inches, architectural asphalt shingles — the dominant roofing material in Sioux City — face a real risk of functional damage: granule loss, cracked tabs, and compromised mat integrity are all plausible, not just cosmetic bruising. Roofs older than 15 years are more vulnerable; aged shingles have less binder resilience and fail at lower impact thresholds than newer installations. A same-day event in Madison, NE reached 4 inches, suggesting this storm system carried substantially greater energy in neighboring areas.
A 2% deductible on a $350,000 home works out to $7,000 out of pocket before insurance pays anything. Typical repair cost for a 2,000 square foot home runs $5,936, with a range of $4,857 to $7,015. 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.

Storm system
This was not an isolated cell. A concurrent event in Madison, Nebraska produced 4-inch baseball-sized hail the same day, indicating a broader, active storm system across the region.
Contractor guidance
Local contractor data shows current backlogs of 2 to 4 weeks in the Sioux City market. The storm chaser risk is assessed as moderate — Sioux City draws out-of-area contractors after regional hail events, and limited local capacity accelerates that exposure. Iowa Code § 103A.71 governs residential contractors performing insurance-related storm repairs and mandates specific contract disclosures; it does not require a state roofing license, but contractors must still carry general liability and workers' comp. Before signing anything, ask for certificates of insurance and confirm the contract includes the required Iowa consumer protection disclosures.
Permits & building code
At 1.75 inches, outcome depends heavily on roof age and existing condition — repair is possible on newer roofs, but replacement is realistic for anything showing prior wear. In Sioux City, the contractor pulls the permit, inspections are required, and permit costs typically run $150 to $350. Class 4 impact-resistant shingles qualify for a 10–20% discount with most Iowa insurers.
