May 15 Storms Drop Large Hail on Lake County: What Homeowners Should Do Now

Last Thursday, May 15, scattered severe thunderstorms rolled across northern Illinois, producing wind damage and hail throughout the region. In parts of northeastern Lake County, hail up to 2 inches in diameter came down, and farther south in the state, hail reached 3 inches with destructive wind gusts up to around 80 mph causing structural damage. If you live in Libertyville, Vernon Hills, Mundelein, Lake Zurich, or anywhere else in the Lake County area, this storm deserves your attention even if your home looks untouched.

Here is why the 2-inch figure matters so much. Asphalt shingles typically start taking real damage when hail reaches about 1 inch in diameter. At 2 inches, a hailstone is roughly the size of a hen egg and carries several times the impact energy of a quarter-size stone. Hail that large does not just cosmetically scuff a roof. It can bruise the shingle mat, knock loose the protective granules that shield the asphalt from the sun, crack shingles outright, and dent or split ridge caps and roof vents. On some roofs it punches through older or brittle shingles entirely.

The damage rarely stops at the shingles. Two-inch hail commonly dents aluminum gutters and downspouts, cracks or holes vinyl siding, dings window wraps and metal fascia, and damages skylights, air conditioner fins, and grills. Those soft metal dents are actually useful evidence. When an inspector or insurance adjuster sees fresh impact marks on gutters and window wraps, it confirms the hail was large enough and dense enough at your address to have damaged the roof above.

The tricky part about hail damage is how invisible it is from the ground. A hail bruise on an asphalt shingle often looks like nothing more than a small dark smudge, if you can see it at all. Up close, it feels like a soft spot, similar to a bruise on an apple, where the fiberglass mat beneath has been fractured. Granules collect in the gutters and at the downspout splash blocks. The roof may shed water fine for months, then begin leaking the following winter or spring as the bruised spots weather, dry out, and open up. By then, connecting the leak back to the May 15 storm becomes much harder.

That timing matters because insurance claims are time-limited. Most homeowner policies require damage to be reported within a set window, often one year from the date of loss, and some are shorter. Waiting until a leak appears can put you outside that window. The smart move after a confirmed large-hail event is to get the roof looked at within a few weeks, while the date of loss is well documented and the damage is fresh and easy to attribute.

We would encourage every homeowner in the affected parts of Lake County to have a professional inspection, even if the roof looks fine from the driveway. A trained inspector will walk the roof, check the shingles for bruising and granule loss, examine the soft metals, and photograph everything. If there is no meaningful damage, you get peace of mind and documentation of your roof's current condition. If there is damage, you have what you need to start a claim on solid footing.
