About Grant County, WI
Grant County sits in the Driftless Area of far southwestern Wisconsin, a rugged, unglaciated land of steep ridges and deep valleys where the Wisconsin River meets the Mississippi near Platteville. Summer storms riding warm, humid air ahead of fronts can drop golf-ball-size stones over the high ground. The KARX radar at La Crosse is the nearest watch, about 70 miles to the north, far enough that its lowest beam rides above this hill country.

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 hail getting worse in Grant County?
Nationally, the research on long-term hail trends is mixed. Better radar coverage since the 1990s makes real increases hard to separate from improved detection. In Grant County, 10 confirmed events have been recorded in 2026 so far, but the tracked record is still short, so it isn't evidence of a lasting trend.
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 Grant County, WI
What this means for your home
If you were just hit
With recent hail in Grant 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 Grant 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.
Claims have deadlines
Policies set a deadline for hail-damage claims, and state law may also apply. Windows range from months to several years depending on your state and policy. Knowing the exact date hail hit your address helps you file on time.
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.
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.
