The Des Moines (KDMX) radar lies about 56 miles to the northeast, a range at which it reads the upper portions of storms somewhat better than near-ground detail.

Does homeowner's insurance cover hail damage?

Is Union 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 Union County's confirmed hail reaches 1.7″. 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.

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