Reported Hail Near Knoxville on August 17, 2026
| Time (UTC) | Hail size | Location | Distance from Knoxville |
|---|---|---|---|
| 2120 | 1.00″ | 1 W Maryville, Blount County | 15.2 mi |
Preliminary Local Storm Reports from the NOAA Storm Prediction Center. Sizes are reported hailstone diameters; times are UTC. Reports can be added or corrected for about a day after the event.
Hail of 1″ and larger — like the 1.00″ reported in this event — can bruise asphalt shingles, knock off protective granules, and dent vents, flashing, and gutters. Much of that damage is not visible from the ground but is typically covered by homeowners insurance when documented promptly.
What to Do If Your Roof Was in the Hail Path
- Check from the ground first. Look for granule piles at downspouts, dented gutters or window screens, and shredded plants — proxies for what hit the roof. Don't climb up yourself.
- Photograph everything with dates. Ground-level damage, hailstones (next to a coin or ruler), and this NOAA report page all support your claim.
- Get a free professional inspection. A local roofer can document bruising and granule loss that is invisible from the ground and give you a written scope of damage.
- Call your insurer only after you know the scope. Sudden storm damage is generally covered; the filing deadline comes from your policy, not from a universal rule — check it and file promptly, while the event date (August 17, 2026) is easy to tie to the damage.
- Meet the adjuster with your contractor. A documented scope from a roofer keeps the adjuster's estimate honest. Full walkthrough: our roof insurance claim guide.
Hail History in Knoxville — This Wasn't the First
NOAA's 10-year archive shows 26 hail events in Knoxville's county, with hail up to 1.75″. In a market with repeat hail, impact-resistant Class 4 shingles often pay for themselves through insurer premium discounts — worth discussing if this event tips you into a replacement.
