Hollister Forensic Weather & Hail Impact Report

Look, I’ve been replacing roofs in this part of the state for over twenty years, and I can tell you Hollister gets hit from a perfect storm of bad luck. We sit right in that corridor where cold fronts rolling down from the mountains slam into the warm, humid air pushing up from the coast. That clash doesn’t just give us a little afternoon shower—it brews up those fast, violent supercells that seem to pop out of nowhere, especially from March through June. And because we’re surrounded by open farmland and flat, low-lying ground, there’s nothing to break up the wind. It comes screaming across those fields, and when it hits your roofline, it’s like a giant hand trying to peel it back. I’ve seen shingles that were nailed down perfectly look like they’d been through a blender after a storm that only lasted fifteen minutes.

The hail is the sneaky part, though. We don’t get the giant softball-sized stuff you see on the news, but we get an awful lot of that quarter-to-golf-ball sized hail that comes down sideways with that wind. That combination is brutal because the wind drives those ice chunks right into the face of your shingles, knocking the granules clean off and bruising the mat underneath. You might not see a single hole, but the roof’s armor is gone, and then the summer sun bakes it until it cracks and curls. Plus, our storm season doesn’t really end—we get a second round of these nasty squalls in the fall when the first cold snaps hit. So if you’ve got a roof that’s over ten years old, it’s not a matter of *if* it’s taken a beating, it’s a matter of how many times it’s been hit without you ever knowing.
