Bismarck (KBIS) is the closest radar, ~36 mi to the southeast, a workable range for decent coverage across the county.

Does homeowner's insurance cover hail damage?

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 Oliver 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 Oliver County's confirmed hail reaches 1.6″. 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 Oliver County, ND
What this means for your home
If you were just hit
With recent hail in Oliver 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 Oliver 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.
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.
