Onalaska Forensic Weather & Hail Impact Report

Look, I’ve been replacing roofs in this county for over fifteen years, and if there’s one thing I tell every homeowner in Onalaska, it’s that we’re sitting right in the bullseye for some of the nastiest weather in Texas. It’s not just bad luck—it’s geography. We’re tucked right along the western edge of Lake Livingston, and that big body of water acts like a heat sponge. When those spring and early summer storm systems roll in from the west, they hit that warm, moist air coming off the lake and just explode. You’ll see these supercell thunderstorms pop up out of nowhere, and they don’t just bring rain—they bring hail the size of golf balls and straight-line winds that can hit 70 or 80 miles an hour. The trees and hills around here funnel that wind right down into the neighborhoods, so your roof takes the brunt of it from every angle, not just one side.

And here’s the thing about our storm season—it’s not a one-and-done deal. We get a nasty stretch from March through June, but then again in late September and October when those cold fronts start clashing with the lingering Gulf humidity. That’s when the hail really gets dangerous, because those late-season storms tend to be slow movers. They’ll park right over the lake and just pound the same few square miles for twenty or thirty minutes. I’ve seen shingles that looked like someone took a shotgun to them, and the worst part is, the damage isn’t always obvious from the ground. You might just see a few missing granules, but the impact has already cracked the matting underneath, and that’s where the leaks start showing up six months later. It’s not a matter of if your roof will take a hit out here—it’s a matter of when, and being ready for it.
