Ping pong-sized hail detected near Chicago, IL on July 3, 2026

Damage assessment

The radar-confirmed strike center was approximately 15 miles southwest of downtown Chicago, with one hail report logged in Cook County on July 3. At 1.5 inches, architectural asphalt shingles — the dominant material in this market — are likely to show granule loss, bruising, and cracked tabs; whether that damage is functional or cosmetic depends heavily on shingle age. Roofs over 10–15 years old are more vulnerable to functional damage because weathered shingles have less impact resistance than new ones. Chicago's housing stock also includes older 3-tab shingles and wood shake in some areas, both of which warrant separate inspection approaches at this hail size.

Historical context

Cook County has limited NOAA storm records — fewer than 10 events of 1 inch or greater in the past decade — so rank claims carry little weight and the record is too thin to draw firm conclusions. What can be said: this July 3 event at 1.5 inches is the largest recorded for the county in that dataset. July has historically produced zero hail events of this size in Cook County, making this occurrence atypical for the month.

Storm system

This was not an isolated event. The same storm system produced hail across a wide corridor on July 3, including golf ball–sized hail (1.75 inches) in Winnebago and Will counties in Illinois and Johnson County in Iowa, with additional reports in DuPage, Kane, St. Joseph, Hamilton, Scott, and Linn counties — spanning Illinois, Indiana, and Iowa.

Contractor guidance

Local contractor data shows current backlogs running 4 to 8 weeks in the Chicago market. The storm chaser risk is rated high — Chicago is a well-known target for out-of-state roofing crews, and door-to-door solicitation can begin within 24 to 48 hours of a significant storm. Illinois requires roofing contractors to hold a state license through the Illinois Department of Financial and Professional Regulation under the Roofing Industry Licensing Act (225 ILCS 335), carry minimum general liability coverage, maintain workers' compensation insurance, and post a surety bond — verify license status through the IDFPR public database before signing anything. Also note: Illinois law prohibits contractors from waiving your deductible; any offer to do so is a statutory violation and a clear red flag.

Permits & building code

At 1.5 inches, outcomes range from spot repairs on newer roofs to full replacement on older or already-degraded surfaces — an inspection determines which applies. In Chicago, the contractor pulls the permit, inspections are required, and permit costs typically run $150 to $400. Class 4 impact-resistant shingles qualify for a 10–20% discount with most Illinois insurers.
