At 3:07 p.m. (EDT) on May 8 2025, the National Weather Service Morristown (NWS‑MRX) issued Severe Thunderstorm Warning #237 for Monroe County.[1] Radar indicated towering 60,000‑ft tops and “ping‑pong‑ball” hail signatures. Spotters later confirmed 2.25‑inch stones in downtown Vonore at 3:24 p.m.

The Vonore, TN Hail Storm developed along a stalled frontal boundary that funneled warm Gulf moisture into an unstable Cumberland Plateau airmass. Updrafts exceeding 120 mph repeatedly lofted embryonic hailstones, allowing multiple ice layers to form before gravity finally won.
Key Takeaways
💡Up to 2.25‑inch hail hammered Vonore on May 8, 2025—large enough to puncture shingles, dent gutters, and shatter skylights.
💡Hidden damage is common. Even if you don’t have an active leak, bruised shingles can void warranties and still qualify for an insurance claim.
💡Tennessee policies generally allow only 12 months to file, so delaying an inspection may cost you your payout.
💡Knoxville‑based Litespeed Construction offers free, no‑obligation roof assessments to document damage exactly the way adjusters expect, increasing claim approval rates.

Why 2.25 Inch Hail Matters
Stones above two inches carry kinetic energy comparable to being struck by a 55‑mph baseball. Asphalt shingles fracture; metal roofs show obvious bruising; skylight acrylic crazes. Insurance carriers label this size “catastrophic hail”, triggering special catastrophe teams to process claims.
How the Vonore, TN Hail Storm Damages Roofs
- Granule Displacement – Large impacts blast protective granules away, exposing UV‑sensitive asphalt.
- Fiberglass Mat Fracture – Microscopic splits grow larger with thermal cycling, eventually leaking.
- Metal Distortion – Dents compromise standing‑seam panels and can void the paint warranty.
- Accessory Damage – Vents, flashing, gutter aprons, and satellite dishes often hide cracks beneath hail scuffs.
Rule of Thumb: Any hail ≥1.75 inches is presumed damaging by most insurance adjusters—Vonore’s 2.25 inch stones leave little doubt.
