May Forensic Weather & Hail Impact Report

Look, I’ve been replacing roofs out here for over twenty years, and if there’s one thing I can tell you about May, it’s that we’re sitting right in the bullseye of what I call “hail alley.” You see, our little spot on the map sits right at the edge of the Hill Country, where the hot, humid air from the Gulf slams head-on into the cooler, drier air coming down from the plains. That collision doesn’t just make for pretty sunsets—it stacks up those towering, angry thunderheads that roll through in the spring and early summer. And because we don’t have any big mountain ranges to break up those storms, they just spin up and park right over us, dropping hail the size of golf balls or bigger. I’ve pulled shingles off homes out here that looked like someone took a shotgun to them, and it’s almost always after one of those April or May supercells that builds up in the afternoon and hits us right around dinner time.

But it’s not just the hail that gets you—it’s the wind that comes with it. When those storms blow through, they’re not just a quick gust; they’re straight-line winds that can hit sixty or seventy miles an hour, and they come at your roof from every angle because of the way the terrain funnels them through the creek beds and low hills around here. That wind gets under the edge of your shingles, lifts them up, and then the hail finishes the job by cracking the fiberglass mat. Once that seal is broken, water has a free path right into your decking, and that’s when you start seeing those ugly brown stains on your ceiling. The kicker is, we get these storms in cycles—some years we’ll go twelve months without a scratch, and then we’ll get two or three nasty ones in a single May. If your roof is older than ten years, or if you’ve got those cheap three-tab shingles, you’re basically rolling the dice every time the sky turns green. I tell folks all the time: in May, it’s not a matter of *if* you’ll get hit, it’s a matter of *when*—and whether you’re ready for it.
