Steeleville, IL Hail Storm – July 2026

Steeleville, IL experienced a concentrated hail event on July 10, 2026. Peak stones were radar-detected at 1.78 inches during an early evening severe thunderstorm that produced multiple NWS warning areas.

What Happened

The main hail-producing period occurred in the early evening and concluded the same night. Five NWS alerts were issued across the Steeleville metro. A dual-polarization radar detection at 6:37 PM CDT (23:37 UTC) identified the largest stones. Subsequent NWS warning-only alerts followed at 6:43 PM CDT (23:43 UTC), 7:20 PM CDT (00:20 UTC), 7:53 PM CDT (00:53 UTC), and 8:41 PM CDT (01:41 UTC). The alerts tracked the storm as it moved through successive warning areas. Radar-derived hail detections indicate a concentrated core early in the sequence, with smaller hail signatures persisting later in the event. The storm is concluded.

Damage Assessment

The largest stones observed by radar are within a size range that commonly produces shingle bruising and metal denting on exposure. Roof coverings with asphalt composition shingles are at increased risk of granule loss, cracked tabs, and localized punctures where shingles were already aged. Exposed aluminum components and soft-metal trim frequently display dents after this magnitude of impact. Vehicle body panels parked outdoors are likely to show dents; glass damage is possible where impact points were direct and concentrated.

Smaller stones that persisted later in the event can still damage older or marginal roof installations and polycarbonate skylights. Landscaped soft materials, like thin plastic planters and vinyl fixtures, often show surface damage over the area swept by the warnings. Incidental damage to rooftop HVAC fins and solar panel frames should be inspected along the path traced by the NWS warning areas.

What Contractors Should Know

Document location and time for every inspection. Capture directional photos of roof planes, gutters, siding, and nearby vehicles. Focus on granule loss patterns, impact dents, and punctures. Record GPS coordinates or address for each finding and note whether the property lay inside an NWS warning area during the event. Triage work by vulnerability: active leaks and compromised glazing first, then cosmetic dents and surface abrasions.

Roofing and glass contractors should consider targeted removal of loose shingles and temporary coverings where leak risk exists. Preserve samples of damaged materials for adjuster review. Metalwork repair requires matching panel geometry and paint; do not assume replacement is necessary without core repair estimates. For rooftop equipment, check coil fins and mounting brackets for impact and vibration damage before restoring service.
