About Ontonagon County, MI
Ontonagon County lies along the Lake Superior shore in Michigan's western Upper Peninsula, a rugged, heavily forested landscape near the Porcupine Mountains. Damaging hail is uncommon here, where the cool lake air and northern climate usually limit storm strength, and what falls tends to come with summer thunderstorms. The Marquette radar (KMQT) sits about 85 miles to the east, far enough that it reads storm tops better than near-ground detail over this corner of the peninsula.
The hail record for Ontonagon County, MI
July is the peak, but the broader risk stretches across spring and into early summer.

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.
Is Ontonagon 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 Ontonagon 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.

No 1-inch-or-larger hail has been confirmed in Ontonagon County so far in 2026.
How much does hail roof damage cost to repair?
It ranges widely. Minor repairs can run a few hundred dollars, while a full roof replacement on an average home often runs $8,000–$20,000+ depending on size, pitch, and material. What you actually pay depends on your deductible and whether your policy is replacement-cost or actual-cash-value.

What this means for your home
Damage can be invisible from the ground
At Ontonagon 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.
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.
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.
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.
