Ping pong-sized hail detected near Rockford, IL on August 21, 2026
Hail was detected at a radar-indicated point within the Rockford 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 landed approximately 6 miles northwest of downtown Rockford, with one hail report logged across Winnebago County that day. At 1.5 inches, architectural asphalt shingles — the dominant material in Rockford's housing stock — are at the threshold where functional damage becomes likely, not just cosmetic. Granule loss, cracked mat, and bruising severe enough to compromise the shingle's weathering layer are realistic outcomes, particularly on roofs older than 10–12 years. Winnebago County has recorded events up to 3 inches, including a severe event on April 8, 2020, that would have caused functional loss across all shingle types — this event is moderate by comparison but not trivial.
On a $350,000 home with a 2% wind/hail deductible, the out-of-pocket threshold is $7,000. Typical repair cost for a 2,000 square foot roof after a 1.5-inch hail event runs $8,742, with a range of $7,153 to $10,332 depending on roof complexity and current labor rates. 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 33rd of 98 documented hail events of 1 inch or greater in Winnebago County over the past 10 years — solidly mid-tier by local standards. The county's largest recorded event was 3-inch hail on April 8, 2020, a level that causes severe functional damage across all residential roofing materials. August sees roughly 7 events per decade in this county, making this storm historically unremarkable for the month.
Storm system
This was not an isolated cell — the same system produced hail across a multi-state corridor, including 1.75-inch hail in Kane County, Illinois, and quarter-sized hail in both Milwaukee, WI and Dane County, WI, suggesting a broad squall line rather than a localized storm.
Contractor guidance
Local contractor data shows current backlogs running 2–4 weeks in the Rockford market. The intake assessment rates storm chaser risk as moderate, consistent with Rockford's history of out-of-area contractors filling capacity gaps after regional events. Illinois requires roofing contractors to hold a state license under the Roofing Industry Licensing Act (225 ILCS 335) — that means a passed licensing exam, general liability coverage, workers' compensation, and a surety bond. Verify license status through the IDFPR public database and ask for proof of all three before signing anything.
Permits & building code
At 1.5 inches, outcomes split between repair and full replacement depending on roof age and pre-existing condition — an inspection will determine which applies. In Rockford, the contractor pulls the permit (typically $150–$350), and an inspection is required before the work is closed out. Class 4 impact-resistant shingles qualify for a 10–20% discount with most Illinois insurers.
- 1Photograph your roof, gutters, downspouts, and any soft metals (AC fins, vents, flashing) while storm damage is still visible and unweathered.
- 2Schedule a professional roof inspection with a licensed Illinois contractor — verify their IDFPR license status before the appointment.
- 3Contact your insurer to report potential damage and ask about your specific policy's reporting window.
- 4Confirm the contractor pulls the required permit and that an inspection is scheduled before the job is closed — do not waive the inspection.
- 5Document all contractor estimates, inspection reports, and communications in writing and keep copies separate from your home files.
