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.
Has Green Bay had hail big enough to total a roof?
3″ hail is in the range where damage can be severe enough to warrant a full roof replacement on standard asphalt shingles. Whether a roof is actually totaled depends on its material and age, how intense the storm was at your specific address, and your insurer's inspection. Hail size alone doesn't decide it.
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.
Should I file a hail claim or pay out of pocket?
It depends on the damage versus your deductible. At the 3″ sizes seen here, damage often exceeds a typical deductible, which can make a claim worthwhile, but get a repair estimate first to compare, and keep in mind that filing can affect future premiums.

What this means for your home
Don't overlook vehicle damage
Hail at the 3″ sizes Green Bay has seen also dents vehicles, cracks glass, and chips paint. Document car damage alongside your roof before any repairs. Both can be part of the same claim.
Read anything before you sign it
Some contractors ask storm-hit homeowners to sign an "assignment of benefits," which can hand control of your insurance claim to them. Read it closely. You can document and file a claim yourself without giving that up.
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.
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.
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.
