If your home was anywhere near the path of the July 27, 2026 storm, check your gutters and soft metal for dents and granule loss before assuming your roof is fine — hail damage is often invisible from the ground, and even a "minor" hit can shorten a roof's remaining life.

What happened on July 27
​
The storms that moved through the region on July 27, 2026 were intense supercell thunderstorms that the National Weather Service's Chicago office says produced several confirmed tornadoes, hail up to 3 inches in diameter, and extensive straight-line wind damage across northern Illinois and northwest Indiana. The worst of it hit the Chicago metro area during the late morning and early afternoon, with a concentrated corridor of giant hail tracking through southwest DuPage County and northwest Will County — putting communities like Downers Grove and Naperville squarely in the path.

Most of the damage in and around Chicago itself came from destructive straight-line winds rather than the hail core, with the hardest-hit areas concentrated in southern Cook and eastern Will counties. Cook County issued a disaster proclamation in the days that followed, and the storm brought widespread power outages, downed trees, and flash flooding to suburbs across the region. Independent storm-damage modeling estimated well over a million and a half homes across the Chicago metro fell inside the hail swath alone, with roughly another million inside the damaging-wind swath.

If you're in Glenview, Northbrook, Evanston, Skokie, Naperville, Schaumburg, Downers Grove, or elsewhere in Chicagoland, there's a real chance your roof took a hit — even if nothing looks obviously wrong from your driveway.

How to check your roof for damage (without climbing up there)
​
Hail and wind damage is frequently invisible from ground level, and a storm-compromised roof can be slippery or structurally weakened — so leave the actual roof walk to a professional. From the ground, here's what you can check yourself:

Gutters and downspouts. Look for small dents, or for granules collecting at the bottom like wet coffee grounds — that granule loss is one of the most reliable early signs of hail impact on shingles.
Soft metal around your property. Window screens, mailboxes, AC unit fins, and vent or pipe caps dent more easily than shingles do. If you see dings on these, your roof very likely took hits too, even if you can't see marks on it from the ground.
Missing, cracked, or displaced shingles, especially near roof edges, ridges, and valleys.
Siding and window screens for cracks, dents, or small holes.
Ceilings and attic spaces for new water stains — a sign of a breach that may not be visible from outside at all.

If you notice any of the above, or you're simply not sure, a free inspection is the fastest way to find out for certain. RS Five's free AI-powered drone inspection checks your entire roof from the air and produces a full Roof Condition Report — a $299 value, offered free — without anyone needing to climb a ladder.

What to do next
Document what you can see now. Photograph any visible damage to your roof, gutters, siding, and yard — including hail on the ground or debris — before storm cleanup gets underway.

Don't wait to schedule an inspection. 

Some damage worsens with continued exposure, and having a documented inspection soon after the storm strengthens any insurance claim you may file later.


Check your policy for reporting requirements. Most homeowners policies ask you to report damage within a specific window — the exact timeframe depends on your carrier and policy, so it's worth a quick call to your agent to confirm yours.

Get an inspection even if it looks fine. Storm damage is commonly missed on a quick visual check, particularly on darker shingles where impact bruising doesn't show much contrast.
Frequently asked questions

Is 3-inch hail unusual for the Chicago area? Yes — that's on the extreme end. Most hail events in the region produce stones closer to marble or golf-ball size. Hail measured at 3 inches is closer to baseball-sized and capable of far more significant impact damage to roofing, siding, and vehicles.

My roof looks fine from the street — do I still need an inspection? If you were in the affected area, it's worth getting one. Hail damage frequently doesn't show up as an obvious hole or crack from the ground — it bruises a shingle's protective layer in a way that shortens its lifespan without being visible until much later.

Will filing a claim raise my insurance rates? It depends on your insurer and your claims history — there's no single answer that applies to every policy. A contractor experienced with storm-related insurance claims can walk you through what to realistically expect for your specific situation before you file.
