Joliet, Illinois experienced golf ball-sized (2") hail on June 7, 2026.

Damage assessment

Golf ball-sized (2") hail poses significant functional damage risk to Joliet's predominantly architectural asphalt shingle roofing. At this magnitude, shingles typically sustain granule loss, exposed mat, and potential cracking that compromises weather protection. Roofs over 10-15 years old face higher vulnerability to penetrating damage. Class 4 impact-resistant shingles would reduce but not eliminate damage potential at this hail size.

Historical context

This event ranks #5 among 118 recorded hail events in the past decade, making it a significant weather occurrence for the area. The largest recorded event was 2.5" hail on September 28, 2019. June historically sees above-average hail activity with 22 events over 10 years, though May remains the peak month.

Storm system

This hail event was part of a broader regional storm system, with quarter-sized hail reported in Hamilton, Indiana and half dollar-sized hail in Marion, Indiana the same day.

Contractor guidance

Current contractor backlogs run 4-8 weeks with moderate storm chaser activity expected. Illinois requires roofing contractors to hold state licenses under the Illinois Roofing Industry Licensing Act (225 ILCS 335) - verify contractor credentials through the IDFPR database before signing contracts. Be aware that Illinois law prohibits contractors from waiving or paying insurance deductibles under the Illinois Roofing Industry Licensing Act. Joliet's dense contractor market provides good options, but scheduling 2-3 weeks ahead helps avoid extended delays.

Permits & building code

At 2" magnitude, roof repair is more likely than full replacement given the functional but not catastrophic damage potential. Contractors handle permit pulling with costs ranging $150-350, and inspections are required. While Class 4 shingles aren't mandated, the 10-20% insurance discount makes them worth considering during any roof work.
