Golf ball-sized hail detected near Green Bay, WI on July 1, 2026
Hail was detected at a radar-indicated point within the Green Bay 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 approximately 12 miles southeast of downtown Green Bay, with one report logged in Brown County on that date. At 1.75 inches, architectural asphalt shingles — the dominant material in Green Bay's housing stock — are susceptible to functional damage: granule loss, cracked tabs, and compromised mat integrity are all realistic outcomes at this size. Roofs older than 10–15 years are more vulnerable; aging shingles lose flexibility and are more likely to crack than deflect impact. Brown County's largest recorded event reached 4.5 inches in September 2021 — this event is notably smaller, but 1.75 inches clears the threshold where functional loss on standard asphalt is credible, not just cosmetic.
On a $350,000 home with a 2% deductible, the threshold to clear is $7,000. Typical repair cost for a 2,000 square foot roof runs $7,309, with a range of $5,980–$8,638. Get a professional inspection before making any insurance decisions.
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 18th out of 76 tracked hail events of 1 inch or greater in Brown County over the past decade — a mid-tier storm, not an outlier. The county's largest recorded event was 4.5-inch hail on September 7, 2021, which likely caused functional loss on every shingle type. July historically averages around 8 hail events per decade in this county, placing this storm squarely within normal seasonal range.
Storm system
No other tracked counties recorded hail activity on July 1, 2026. This appears to be an isolated, localized event rather than part of a broader regional system.
Contractor guidance
Local contractor data shows current backlogs of 2–4 weeks in the Green Bay area. Storm chaser risk is assessed as moderate — Green Bay's contractor market has limited post-storm capacity, and out-of-area contractors commonly move in after regional hail events. Wisconsin does not require a state-issued roofing license, but contractors should be registered with the Wisconsin Department of Safety and Professional Services if they hold themselves out as engaged in a regulated trade. Before signing anything, verify general liability coverage, workers' compensation, and any bonding required by local ordinance — and know that Wisconsin law prohibits contractors from waiving or absorbing your deductible.
Permits & building code
At 1.75 inches, outcomes range from repair to full replacement depending on roof age and existing condition — a professional assessment is the only way to determine scope. The contractor pulls the permit in Green Bay, costs run $150–$350, and a municipal inspection is required. Class 4 impact-resistant shingles qualify for a 10–20% discount with most Wisconsin insurers.
