How big does hail need to be to damage a roof?
Hail 0.75" (dime-size) can dent soft metals. Hail 1.0" (quarter-size) bruises asphalt shingles and causes granule loss. Hail 1.5"+ (golf ball-size) causes structural damage most insurers will cover for full replacement. A qualified roofing contractor or public adjuster can identify claim-eligible damage that isn't visible to the untrained eye.
What time of year does Illinois get the most hail?
