About Williamson County, TN

Spring is the active season, when strong frontal systems and abundant Gulf moisture fuel severe storms capable of producing large hail, sometimes reaching tennis ball size. The Nashville (KOHX) radar sits about 31 miles to the northeast, near enough to resolve storm cores as they track through the area.

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 Williamson County had hail big enough to total a roof?
2.8″ 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 2.8″ 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 2.8″ sizes Williamson County 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.
If you were just hit
With recent hail in Williamson 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.
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.
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.
