Hail Damage in Rock Island County, IL

Rock Island County, IL has recorded 11503 hail events within a 30-mile radius of the county center since 2015, based on NOAA NEXRAD radar data. With over 11503 events in a decade, Rock Island County is considered a high-risk hail area.

The largest hail event recorded near Rock Island County reached 4 inches. The average hail size across all events is 1.02 inches. Hail of 1 inch or larger can bruise or crack asphalt shingles, and at 2 inches or larger a professional roof inspection is the normal next step after a storm. A recorded size is exposure, not a damage finding. Only a licensed roof inspection can determine whether a specific roof was damaged; coverage depends on the policy and carrier.

Hail season in Illinois typically runs April through July. During these months, atmospheric conditions create powerful thunderstorms capable of producing large hail. Rock Island County residents should inspect their roofs after any storm and consider a professional inspection each spring.

Many standard homeowner's policies in Illinois include hail under a "wind and hail" peril, but coverage and deductibles differ from one policy to the next. Claim deadlines and coverage rules vary by carrier and policy — confirm yours with your insurer or your state's insurance department. Document what you observe promptly. Even when nothing is obvious from the ground, a licensed roofer can check for impacts during an inspection — and that inspection, not a hail record, is what shows whether a roof was damaged.

Hail damage repair costs in Rock Island County typically range from $8,000–$25,000+ for full roof replacement. The final cost depends on roof size, pitch, material type, and the extent of damage a licensed inspection finds. Whether a confirmed repair is covered, and what deductible applies, depends on your policy and carrier. Getting more than one contractor estimate before deciding whether to file is a reasonable step.

A HailScore is a 0–100 risk index that measures historical hail activity near a specific property. The score is calculated from five factors derived from NOAA NEXRAD radar data: storm frequency, recency, hail size, cumulative damage, and proximity. A score of 0–25 is Low, 26–50 is Moderate, 51–75 is High, and 76–100 is Very High — the same sacred bands used on the live report.
