About Cook County, MN
Cook County occupies the far northeastern tip of Minnesota, the Arrowhead region of boreal forest and rocky ridges along the Lake Superior shore. Hail is rare here, as the cool lake air stabilizes the atmosphere and tends to calm storms before they can produce ice. The Duluth (KDLH) radar lies about 108 miles to the southwest, so distant that it senses only the tops of storms over the county rather than their lower structure.
The hail record for Cook County, MN
The dangerous window runs spring into early summer, with June the busiest month on record.
Cook County is no Plains hot spot, but the storms that do reach it have still dropped hail up to 1″.

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 Cook 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 Cook County's confirmed hail reaches 1″. 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 Cook County, MN
What this means for your home
If you were just hit
With recent hail in Cook 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 Cook 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.
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.
Replacement cost vs. actual cash value
An RCV policy pays to replace your roof at today's prices; an ACV policy subtracts depreciation for the roof's age, which can mean a much smaller check on an older roof. Knowing which you carry shapes what a hail claim is actually worth.
