Golf ball-sized hail detected near Green Bay, WI on September 2, 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 return centered approximately 11 miles east of downtown Green Bay, with one hail report logged in Brown County that day. At 2 inches, golf ball-sized hail causes functional damage to standard architectural asphalt shingles — the dominant material in Green Bay's housing stock — not just cosmetic bruising. Granule loss, cracked tabs, and compromised underlayment are realistic outcomes, particularly on roofs older than 10 years. Brown County's record includes a 4.5-inch event in September 2021, so this storm ranks well below the county's worst, but 2 inches is enough to shorten a roof's service life regardless.
On a $350,000 home with a 2% wind/hail deductible, your out-of-pocket threshold is $7,000. A typical repair on a 2,000 square-foot roof runs $7,710, with a replacement estimate around $12,851. 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.

The largest event on record for the county reached 4.5 inches on September 7, 2021.

Contractor guidance
Local contractor data shows current backlogs running 2 to 4 weeks in the Green Bay market. The intake assessment rates storm chaser risk as moderate — Green Bay draws out-of-area contractors after significant regional hail events, and a golf ball event qualifies. Wisconsin does not issue a state-level roofing license, but contractors should be registered with the Wisconsin Department of Safety and Professional Services if they operate in a regulated trade capacity. Before signing anything, confirm general liability coverage, workers' compensation, and any bonding required by Brown County or municipal ordinance.
Permits & building code
At 2 inches, a full replacement is possible depending on roof age and the inspection findings — repairs are not always code-compliant when damage is widespread. Brown County requires a permit for roofing work; your contractor pulls it, and an inspection is required, with permit fees typically running $150 to $350. Class 4 impact-resistant shingles qualify for a 10–20% discount with most Wisconsin insurers.
