About Mercer County, MO

Hail is rare here, with stones falling mainly when summertime storms build along a front in the warm, humid air drawn up from the south. The Des Moines radar (KDMX) lies about 91 miles to the north, far enough that it samples the upper portions of storms more reliably than low-level detail.

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