Golf ball-sized hail detected near Davenport, IA on July 4, 2026

Damage assessment

The radar-indicated strike was approximately 15 miles northwest of downtown Davenport, with one confirmed hail report logged in Scott County that day. At 2.25 inches, golf ball-sized hail is large enough to cause functional damage — not just cosmetic — to standard architectural asphalt shingles, particularly roofs over 10–15 years old where granule adhesion has already degraded. Newer shingles may show bruising and granule loss without immediate leaks, but the underlying mat can be compromised in ways that shorten remaining service life. Older 3-tab shingles and wood shake, which appear in Davenport's established neighborhoods, are more vulnerable and warrant close inspection.

Historical context

With at least 10 events on record, this event ranks 8th of 131 hail events of 1 inch or greater recorded in Scott County over the past decade — placing it among the stronger storms in the local history. The largest recorded event reached 4 inches on April 4, 2023. July is historically below average for hail activity in this county, with only 5 July events logged over 10 years; April is the peak month at 79 events.

Storm system

This was not an isolated event. The same storm system produced hail across a wide corridor on July 4, 2026, with reports ranging from 0.75 inches in Linn County, Iowa to 2.25 inches in Kane County, Illinois — suggesting an organized multi-cell or squall line system consistent with the warm-season MCS patterns common through eastern Iowa and northern Illinois.

Contractor guidance

Local contractor data shows current backlogs running 4–8 weeks in the Davenport market, so scheduling sooner rather than later is practical. The storm chaser risk here is rated high — Davenport draws out-of-state roofing contractors after significant events, and door-to-door solicitation can begin within 24–48 hours of a storm. Iowa Code § 103A.71 prohibits contractors from waiving your insurance deductible and imposes mandatory contract disclosure requirements for insurance-related repair work — this isn't optional. Before signing anything, verify the contractor carries general liability insurance and workers' comp, and confirm the contract includes the required Iowa consumer protection disclosures.

Permits & building code

At 2.25 inches, full roof replacement is a real possibility on older roofs, though repair may suffice on newer installations depending on inspection findings. In Davenport, the contractor pulls the permit — expect permit costs between $150 and $400, and a required inspection before work is considered complete. Class 4 impact-resistant shingles qualify for a 10–20% discount with most Iowa insurers.
