Chewalla Forensic Weather & Hail Impact Report

Look, I’ve been replacing roofs in this part of Tennessee for over twenty years, and I can tell you straight up—Chewalla sits right in a bullseye for nasty weather. We’re tucked up against the hills and hollows of the Cumberland Plateau, and that terrain acts like a funnel for spring and early summer storm systems. When those cold fronts come screaming down from the north and slam into the warm, humid air that pools in the valleys, the atmosphere just stacks up. You get these supercell thunderstorms that spin up out of nowhere, and instead of blowing over, they stall right on top of us, dropping hail the size of golf balls for twenty minutes at a time. It’s not just the size of the stones either—it’s the wind. Those downdrafts come off the ridges and whip around the treeline, so you get hail hitting your shingles from one direction and then a gust slamming them from another, prying them loose before the ice even has a chance to melt.

And here’s the thing that catches a lot of folks off guard: we don’t just get one bad storm a year. Our severe season runs from March all the way through June, and then we get a second round in late October and November when the leaves are off the trees and the wind can really get a straight shot at your roofline. The hail might be smaller in the fall, but it’s more frequent, and those autumn storms come with straight-line winds that can hit sixty or seventy miles an hour. I’ve seen brand new architectural shingles that were rated for 130 mph winds get shredded because the hail had already bruised the fiberglass mat, and then the next wind event just peeled them back like a sardine can. The combination of that rough terrain, the seasonal timing, and the fact that our storms tend to be slow-moving means your roof takes a beating that a house down in Memphis or Nashville just doesn’t see. That’s why I always tell my Chewalla customers—if you hear thunder, you better check your gutters for granules the next morning, because that’s the first sign the damage is already done.
