Cobb Forensic Weather & Hail Impact Report

Look, I’ve been replacing roofs up here in Cobb for over twenty years, and I can tell you firsthand that our geography is working against us. We sit right in that corridor where the warm, moist air from the Gulf bumps into the cooler air rolling down off the Blue Ridge, and that collision is a recipe for trouble. It doesn’t matter if it’s a random April thunderstorm or a late-summer pop-up; those cells can explode right over Kennesaw Mountain and drop hail the size of golf balls before you even get the car in the garage. The wind is just as nasty—those straight-line gusts can hit sixty or seventy miles an hour, and they come at your roof from every angle, not just one direction like a hurricane. That’s what lifts shingles and tears off flashing, and once the water gets under that first layer, the whole deck is done for.

And it’s not just the big spring storms you have to worry about. Our hail season really ramps up in March and April, but I’ve seen damaging hail as late as October, and we get those weird winter squalls too that sneak in with freezing rain and high winds. The problem is the hail here isn’t always the big, dramatic stuff—it’s often that dense, pea-to-quarter size that hits like a thousand little hammers, bruising the asphalt and knocking the granules right off. That leaves your shingles sunbaked and brittle by July, so when the next storm rolls through, they crack and split instead of flexing. Add in the fact that a lot of homes in Cobb have steep pitches and lots of valleys, and you’ve got a perfect setup for wind to catch an edge and peel it back like a sardine can. I’m not trying to scare you, but if your roof is over ten years old, you’re playing roulette every time the sky turns green.
