Kane County Storm History — What Actually Hit, and When
After a storm, everyone wants to know one thing: was my house under it? This is our record of the severe weather that has crossed Kane County and the surrounding suburbs, taken from National Weather Service Chicago event summaries.
Every entry links to the Weather Service's own record. We have deliberately included only ground reports — measured gusts and observed hail and damage. Radar-estimated hail swaths cover a much wider area and are frequently used by storm chasers to claim a town was hit when no damage was ever reported there.

Absence of a report for your town is not evidence your roof is fine. Small villages generate few reports simply because there are fewer spotters and stations in them — no National Weather Service report names Wayne, Illinois in either year, and Wayne sits a few miles from an EF-1 tornado track.
Why 2026 Was Unusual
Two derechos in one summer is not normal. Neither is a tornado outbreak that produces 24 tornadoes in the Chicago forecast area — the second-largest on record — or a 6.60-inch hailstone that breaks the Illinois state record.
The insurance data says the same thing. Illinois ranked second in the nation for State Farm hail claims in 2024 and third in both 2023 and 2025. Through June 19, 2026, Illinois State Farm homeowner claims were running 47% above the ten-year average, with auto catastrophe claims 101% above.
That has consequences beyond roofs. Illinois homeowner premiums rose roughly 50% over three years, and State Farm raised Illinois rates more than 27% effective August 2025. Which is exactly why it is worth knowing whether a genuine claim exists on your roof before you decide whether to file one.
What to Do If You Were Under One
1. Get it looked at, from the roof. Not from the driveway and not from a satellite image. Our estimate is free, takes about 45 minutes, and you get the photographs whether or not you file a claim or hire us.
2. Do not sign anything on the doorstep. Illinois requires home repair contracts over $1,000 to be in writing and gives you three business days to cancel a home-solicitation contract. For disaster-repair contracts you get five days to cancel after an insurance claim is denied.
3. Check the license. Illinois licenses roofing contractors at state level and requires the number on advertising, contracts and permits. Ours is 104.004825. The Illinois Attorney General issued a formal storm-chaser consumer alert in May 2025 for exactly this reason.
4. Be suspicious of deductible offers. Paying or rebating your deductible is illegal in Illinois. So is a discount conditioned on filing a claim.
