Tennessee Hail & Storm Roof Damage

Tennessee’s storm story is hail: supercells crossing Middle and West Tennessee drop damaging stones every spring, and flat commercial roofs in the Nashville and Memphis corridors take the worst of it. This page tracks the state’s verified hail history from live CapXos data — county by county, year by year.

Tennessee storm season

Hail season peaks March–June, with a secondary fall window. Unlike coastal states, Tennessee’s storm damage is dominated by hail and straight-line wind rather than hurricanes — inspection demand follows within days of each event.

Tennessee storm damage FAQ

What hail size starts damaging a commercial roof in Tennessee?

One-inch stones (quarter size) can bruise an aged single-ply membrane; at 1.5–2 inches, damage to healthy membranes, metal flashing, and rooftop units is likely. Tennessee records stones above 2 inches most years — check the max magnitude for your county in the data above.

My roof took hail but isn’t leaking — do I still have a claim?

Possibly, and this is exactly when documentation matters. Hail bruising shortens membrane life long before leaks appear, and most policies cover the damage when it’s identified within the claim window — not when the leak finally shows. A prompt inspection converts invisible damage into a documented, claimable loss.

Are roofing permits required for hail damage repairs in Tennessee?

Requirements vary by city and county — Nashville and Memphis require permits for reroofing and substantial repairs, while some rural counties are lighter-touch. Permit activity after major hail events is still a good market signal: it shows where owners are actually commissioning work.
