Sunnyvale Forensic Weather & Hail Impact Report

Look, I’ve been replacing roofs in this part of Texas for over twenty years, and I can tell you straight up—Sunnyvale gets hammered in a way folks don’t expect until they see their own shingles scattered across the yard. We sit right in that nasty corridor where warm, moist air from the Gulf slams into cooler fronts rolling down from the Red River. That’s a recipe for supercell thunderstorms, and when those pop up, they don’t just bring a little rain. They bring hail the size of golf balls or bigger, and straight-line winds that can hit sixty or seventy miles an hour without even blinking. The geography here is flat, wide open, and dotted with new subdivisions—there’s nothing to break that wind up, so it just screams across the rooftops, lifting edges and peeling shingles like they’re stickers.

And it’s not a once-in-a-blue-moon thing. Our severe weather season runs from March through June, with a second nasty spike in the fall around October. I’ve seen three major hailstorms in a single spring here, and each one can leave your roof looking like someone took a shotgun to it. The problem is, a lot of these homes have architectural shingles that are rated for lower impact, and the heat we get in July and August makes them brittle. So when that first big storm hits in the spring, the granules are already loose, the sealant is weak, and the wind just finds that one weak spot. Before you know it, you’ve got water dripping in the guest bedroom, and I’m up there pulling off half the decking. It’s not a matter of *if* you’ll get hit—it’s a matter of *when*, and being ready for it is the only thing that saves your drywall.
