[See every warning for your address](https://chicagostormpros.com/map/) [Free Inspection](#inspection-form) Chicagoland roofs have been through one of the most active severe weather stretches in recent memory. Between June 10 and August 1, 2026, the metro took a derecho, one of the largest local tornado outbreaks on record, multiple hail events, overnight wind storms, a fatal Independence Day storm, a multi-tornado event with NWS-surveyed tracks, and a flash flood event that exposed every roof the earlier storms had quietly damaged. This timeline exists for one reason: your insurance claim depends on tying your roof damage to a specific, documented date of loss. Every event below is sourced to National Weather Service Chicago write-ups, NWS damage surveys, or Storm Prediction Center reports, and each carries its own claim filing deadline under the typical Illinois 12-month window.

Widespread tree, fence, and roof damage was reported across Cook, DuPage, Kane, and Will counties. **Typical claim deadline: June 10, 2027.** [NWS Chicago event write-up](https://www.weather.gov/lot/2026_06_10_Derecho). ## June 11, 2026: Tornado Outbreak The second-largest tornado outbreak on record in the NWS Chicago area: 23 local tornadoes out of at least 51 regionally, including an EF-3 with 165 mph winds near Kouts, Indiana, an EF-2 that tracked from Hickory Hills to Garfield Ridge in Chicago, and an EF-0 from Naperville to Lisle. Destructive straight-line winds hit the metro south of the Kankakee River. **Typical claim deadline: June 11, 2027.** [NWS Chicago event write-up](https://www.weather.gov/lot/2026_06_11_SevereWeather). ## June 24, 2026: Huntley Tornado Report and Evening Hail Evening severe thunderstorms brought Severe Thunderstorm Warnings carrying 1.25 inch hail and 60 mph wind tags across the metro. Near Huntley in McHenry County, video showed a likely tornado with lofted debris, and the county EMA reported roof damage to a barn along Harmony Road. **Typical claim deadline: June 24, 2027.** [SPC storm reports](https://www.spc.noaa.gov/climo/reports/260624_rpts.html). ## July 2-3, 2026: Overnight Severe Storms Overnight storms brought 60 mph wind and 0.75 inch hail warnings across Kane, Cook, and DuPage counties, followed by flood advisories. In St. Charles, a tree fell onto an elderly couple's home; firefighters rescued them uninjured. Overnight storms are the ones homeowners sleep through and never connect to the ceiling stain that shows up weeks later. **Typical claim deadline: July 2, 2027.** [SPC storm reports](https://www.spc.noaa.gov/climo/reports/260702_rpts.html). ## July 4, 2026: Independence Day Storms and Flooding Severe Thunderstorm Warnings with 60 mph wind, hail, and tornado-possible tags covered the western and southern suburbs on the holiday, followed by Flash Flood and Flood Warnings. Near Millbrook in Kendall County, a tree fell on a camper trailer off Millbrook Road, killing one person. Trees came down across the Millbrook, Oswego, and Aurora corridor. **Typical claim deadline: July 4, 2027.** [SPC storm reports](https://www.spc.noaa.gov/climo/reports/260704_rpts.html). ## July 27, 2026: Multi-Tornado Event The biggest single day for metro roof damage since June 11. NWS damage surveys confirmed an EF-1 tornado with 110 mph winds on an 11.4-mile path through Hazel Crest, Country Club Hills, Markham, and Glenwood; a second EF-1 near Glenwood; and EF-0 tornadoes in Wheaton, Downers Grove, Romeoville, and Orland Park, with a photographed tornado in north Glen Ellyn. An 82 mph gust was measured at Beach Park near Waukegan, where a roof was blown off an apartment building. Full details, community by community, are in our [July 27 tornado recap](https://chicagostormpros.com/blog/july-27-2026-tornadoes-chicagoland-recap/). **Typical claim deadline: July 27, 2027.** [SPC storm reports](https://www.spc.noaa.gov/climo/reports/260727_rpts.html). ## August 1, 2026: Flash Flooding Slow-moving thunderstorms dumped heavy rain across the metro, triggering a Flash Flood Warning and a Flood Warning from NWS Chicago. Rain alone usually isn't a covered cause of roof damage, but this event mattered for a different reason: it was the stress test that revealed every roof weakened in June and July. If you saw ceiling stains, attic moisture, or a damp top floor on August 1, the cause almost certainly dates to one of the events above, and that earlier event is the one your claim should reference. ### Not Sure Which Storm Hit Your Roof? A free 45-minute inspection produces a photo report that ties your damage to a specific documented storm date. That's the foundation of a claim that gets paid.

The 2026 season opened with the **March 14 hailstorm** that dropped baseball-sized hail on DuPage County, including a 4.8 inch stone documented in Darien. The **April 17 outbreak** brought multiple confirmed tornadoes, 76 mph gusts, and 2.25 inch hail across Kane, Cook, Will, McHenry, and Lake counties (full details in our [April 17 recap](https://chicagostormpros.com/blog/april-17-2026-tornadoes-chicagoland-recap/)). The **April 27 wake low** produced 45 to 77 mph non-thunderstorm winds across the region, peaking at 72 mph in Sandwich. The **May 18 morning storms** produced wind damage across Cook, Kankakee, and Lake (IN) counties, a brief EF-0 near Paxton, and a 79 mph gust at Midway Airport. Typical 12-month deadlines for the spring events: **March 14, 2027** for the hailstorm, **April 17, 2027** for the tornado outbreak, **April 27, 2027** for the wake low, and **May 18, 2027** for the morning storms. If your roof took a hit in spring and you never filed, the window is still open, but every new storm gives your carrier an alternative explanation for the damage. ## What to Do With This Timeline **First, figure out which event hit you.** Our [storm map tool](https://chicagostormpros.com/map/) plots every NWS warning polygon that covered your exact address over the past 12 months, with dates and issuing office. Match that against the timeline above and you'll know your likely date of loss in about two minutes. **Second, get the damage documented.** A Haag-certified inspection produces a photo report with hit counts, measurements, and damage locations per roof slope. That report, tied to a specific storm date, is what turns a claim from an argument into paperwork. The inspection is free and takes about 45 minutes. **Third, file while the event is fresh.** The full process, from filing through the adjuster meeting, supplements, and final payment, is laid out step by step on our [roof insurance claims page](https://chicagostormpros.com/insurance-claims/). For most insured storm damage, homeowners pay only their deductible. Illinois law also protects you: carriers can't raise your rates for a single weather-related claim under 215 ILCS 5/143.17a. **Fourth, don't wait for the next storm to make the decision for you.** This summer demonstrated the pattern clearly: damage compounds. Roofs weakened in June failed in July. Roofs lifted in July leaked in August. The cheapest point to act on storm damage is always right after it happens, with documentation in hand. ## Free Post-Storm Inspection Same-day and next-day appointments available.

Haag Certified GAF Master Elite BBB A+ Accredited Based in Hillside, IL Common Questions ## Summer 2026 Storm FAQs How many major storms hit Chicagoland in summer 2026? Between June 10 and August 1, 2026, the Chicago metro saw at least seven significant severe weather events: the June 10 derecho, the June 11 tornado outbreak (23 tornadoes in the NWS Chicago area), the June 24 evening hail and Huntley tornado report, the July 2-3 overnight storms, the July 4 severe storms and flooding, the July 27 tornado event with multiple NWS-confirmed tracks, and the August 1 flash flooding. That follows a spring that included the March baseball-sized hailstorm in DuPage County, the April 17 tornado outbreak, the April 27 wake low wind event, and the May 18 morning storms. What is the claim filing deadline for each 2026 storm? Most Illinois homeowner policies require filing within 12 months of the date of loss. Working deadlines: March 14, 2026 hail becomes March 14, 2027. April 17 tornadoes become April 17, 2027. April 27 winds become April 27, 2027. May 18 storms become May 18, 2027. June 10 derecho becomes June 10, 2027. June 11 tornado outbreak becomes June 11, 2027. June 24 hail becomes June 24, 2027. July 2 storms become July 2, 2027. July 4 storms become July 4, 2027. July 27 tornadoes become July 27, 2027. Check your own policy, because some carriers enforce shorter windows. My roof was hit by more than one storm this year. Which event do I file under? That depends on which storm caused the documented damage, and it's exactly why a professional inspection matters. An inspector can often distinguish fresh hail bruising from older hits and lifted shingles from broken seals, then tie the damage to a specific date using NWS event records. Filing under the correct date of loss protects the claim. Filing late under the wrong event gives the carrier a reason to push back. Does the August 1 flooding count as storm damage for a roof claim? The August 1 event was a heavy rain and flash flooding event, and rain by itself usually isn't a covered cause of roof damage. What it did do was expose pre-existing damage: roofs bruised by hail or lifted by wind in June and July let water in under sustained rain on August 1. Interior water damage from a roof opening caused by a covered storm is generally part of the storm claim. If you saw ceiling stains or attic moisture on August 1, the underlying cause likely dates to an earlier 2026 storm. Is it too late to file for the spring 2026 storms? No. Under the typical 12-month window, claims for the March hailstorm can be filed until March 2027, and the April and May events carry deadlines in spring 2027. But waiting is working against you. Carriers scrutinize late claims harder, and each new storm gives them an argument that your damage came from a different event than the one you're claiming. File while the documentation is clean.
