Does homeowner's insurance cover hail damage?
Hail is a covered peril under most standard homeowner's policies (typically HO-3), subject to your deductible. Whether you have replacement-cost or actual-cash-value coverage makes a big difference in what's paid out. Your declarations page will say which.
How do I know if my roof was damaged by hail?
Common signs are granules collecting in gutters and downspouts, bruised or cracked shingles, and dents on soft metals like vents, flashing, and gutter tops. A lot of hail damage isn't visible from the ground, so a professional inspection is the reliable check.
Is Grundy County's hail big enough to damage a roof?
It can be. Asphalt shingles can begin showing functional damage in the ¾-to-1-inch range, and Grundy County's confirmed hail reaches 1.3″. At these sizes damage is often hard to see from the ground, so whether it's a claimable loss depends on shingle type, age, and an inspection.
Hail just hit, what should I do?
Safely photograph any hail and note the time, then confirm what radar recorded at your address before calling your insurer. Most policies require prompt notice after a hail event, and deadlines vary by policy and state, so don't wait to document it.
Recent confirmed hail near Grundy County, IL
What this means for your home
If you were just hit
With recent hail in Grundy County, you're still in the window to document and report it. Photograph any damage, note the storm date, confirm what radar detected at your address, and review your policy's reporting requirements. Deadlines vary.
Damage can be invisible from the ground
At Grundy County's typical sizes, hail often bruises shingles and loosens granules without obvious holes, shortening roof life in ways that are easy to miss until the next storm or an inspection.
Document before you repair
If you suspect hail damage, photograph it and note the storm's date before making any repairs. Undocumented or already-fixed damage is much harder to claim later.
Keep a 'before' record
Photos of your roof and exterior in good condition make new hail damage much easier to prove later. A few shots now, before the next storm, can save an argument with an adjuster over what's old wear and what's storm damage.
Get more than one estimate
After a damaging storm, reputable local roofers get busy and out-of-town crews flood in. Get multiple written estimates and verify licensing and local references before signing anything.
Know your hail deductible
Many policies in hail-prone states use a percentage deductible, often 1–2% of the home's insured value rather than a flat dollar amount. On a $400,000 home that can be $4,000–$8,000 out of pocket before coverage starts, so it's worth checking your declarations page before a storm.
