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.
Is Warren 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 Warren County's confirmed hail reaches 1″. 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.
Is hail getting worse in Warren County?
Nationally, the research on long-term hail trends is mixed. Better radar coverage since the 1990s makes real increases hard to separate from improved detection. In Warren County, 2 confirmed events have been recorded in 2026 so far, but the tracked record is still short, so it isn't evidence of a lasting trend.

What this means for your home
If you were just hit
With recent hail in Warren 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.
Damage can be invisible from the ground
At Warren 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.
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.
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.
