Golf ball-sized hail detected near Green Bay, WI on June 24, 2026

Damage assessment

The radar-confirmed strike landed approximately 4 miles west of downtown Green Bay, with one hail report logged in Brown County that day. At 2.25 inches, golf ball-sized hail routinely causes functional damage to architectural asphalt shingles — not just cosmetic bruising, but granule loss and cracked mat that shortens roof life and can void manufacturer warranties. Shingles older than 10–15 years are more likely to show functional failure at this size; newer roofs may show impact marks with less structural compromise. Brown County's largest recorded event reached 4.5 inches in September 2021, so while today's event is meaningful, it is not at the upper end of what this county has seen.

Historical context

This event ranks 13th out of 76 hail events of 1 inch or greater recorded in Brown County over the past 10 years — solidly in the upper tier by magnitude. The county's record event was a 4.5-inch storm on September 7, 2021. June historically produces above-average hail activity here, with 21 documented events over the past decade.

Storm system

This was not an isolated cell. The same system produced hail across a wide corridor: quarter-sized in Dane County, WI, half-dollar in Winnebago County, IL, and ping pong ball-sized in DuPage County, IL — indicating a broad storm track moving through the region.

Contractor guidance

Local contractor data shows current backlogs of 2–4 weeks, which is typical for a moderate-density market after a regional event. The intake assessment rates storm chaser risk as moderate — Green Bay does draw out-of-area contractors following significant regional hail, so vet carefully. Wisconsin does not issue a state-level roofing contractor license, but contractors should be registered with the Wisconsin Department of Safety and Professional Services if they hold themselves out in a regulated trade. Before signing anything, verify general liability coverage, workers' comp, and any bonding required by Brown County or the City of Green Bay.

Permits & building code

At 2.25 inches, repair is possible on newer roofs, but replacement is common once adjusters document functional damage across enough of the surface. The City of Green Bay requires the contractor to pull the permit — budget $150–$350 — and an inspection is required before the job closes. Class 4 impact-resistant shingles qualify for a 10–20% discount with most Wisconsin insurers.
