Golf ball-sized hail detected near Rockford, IL on July 3, 2026

Damage assessment

The radar-confirmed strike landed approximately 14 miles northwest of downtown Rockford, with one hail report logged in Winnebago County that day. At 1.75 inches, architectural asphalt shingles — the dominant roofing material in Rockford — are vulnerable to functional damage: granule loss, cracked mats, and compromised seals that may not be visible from the ground. Roofs older than 15 years are most exposed; aging shingles have less resilience and may show damage at lower thresholds. Winnebago County's largest recorded event reached 3 inches on April 8, 2020, a size capable of functional loss on essentially all shingle types — today's event was smaller but still above the threshold where real structural damage occurs.

Historical context

This event ranks 20th out of 98 hail events of 1 inch or greater recorded in Winnebago County over the past 10 years — a mid-tier event by local standards. The county record stands at 3 inches on April 8, 2020. July historically produces about 13 hail events per decade here, making this timing unremarkable; April is the county's most active month with 36 events over the same period.

Storm system

This was not an isolated strike. The same system produced golf ball-sized hail in Johnson County, Iowa, and Will County, Illinois, with additional reports ranging from quarter- to ping pong-sized hail across Kane, DuPage, Cook, Scott, Linn, and St. Joseph counties — a broad multi-state corridor of hail activity on July 3.

Contractor guidance

Local contractor data shows current backlogs of 2 to 4 weeks in the Rockford market. The intake assessment rates storm chaser risk as moderate — Rockford's contractor market tightens after major regional events, and out-of-area crews fill that gap. Illinois requires roofing contractors to hold a state license under the Roofing Industry Licensing Act (225 ILCS 335), carry minimum liability coverage, maintain workers' compensation, and post a surety bond — verify any contractor's license status through the IDFPR public database before signing. Also know that Illinois law prohibits contractors from offering to waive or absorb your deductible; any such offer is a statutory violation and a clear red flag.

Permits & building code

At 1.75 inches, some roofs will need full replacement rather than spot repair, particularly if shingles are older or the hail coverage was dense — a licensed inspector can tell the difference. In Rockford, the contractor pulls the permit, inspection is required, and permit costs typically run $150 to $350. Class 4 impact-resistant shingles qualify for a 10–20% discount with most Illinois insurers.
