Storm Center questions
Was there hail in Knoxville today?
Check the alerts and the latest storm reports at the top of this page. Reports are preliminary and depend on someone reporting hail, so also check your own gutters, vents and car.
What should I do first after a storm damages my roof?
Stay safe, photograph the damage and any hailstones with dates, cover openings with a tarp and keep receipts, check your deductible, then report the claim. Use the printable after-the-hail checklist.
What should I ask my insurance adjuster?
Ask what damage was found on each slope, whether the roof will be repaired or replaced and why, which line items and code items are included, how depreciation was calculated and how to submit a supplement. Print our adjuster question list.
