Cary Forensic Weather & Hail Impact Report

Look, I’ve been replacing roofs in the Triangle for over fifteen years, and if there’s one thing I tell every homeowner in Cary, it’s that your neighborhood sits right in the bullseye for some of the nastiest spring and summer weather in the state. We’re not just dealing with a random thunderstorm here and there. Because of the way the terrain rolls from the Piedmont down toward the coast, warm, moist air from the Gulf gets shoved up against cooler air coming off the mountains, and that collision happens almost directly over us. That’s why, come April through June, we’ll see those pop-up supercells that seem to explode out of nowhere by late afternoon. Those aren’t just rainmakers—they’re hail factories. The updrafts are so violent that ice pellets get tossed around in the clouds for a long time before they fall, so by the time they hit your shingles, they’re the size of golf balls or bigger, and they’re coming down sideways at 60 miles an hour.

And here’s the kicker that a lot of folks don’t realize until it’s too late: it’s not just the hail itself, it’s the wind that rides in with it. Cary’s got all these mature oaks and pines, and the storm fronts that roll through here tend to bow out and create these straight-line wind bursts that can hit 80 or 90 miles an hour. That’s hurricane-force wind, but without the warning. I’ve seen entire neighborhoods where the shingles look fine from the street, but the wind has lifted the tabs and peeled back the sealant, leaving every single nail head exposed to the next rain. Then, when the next hailstorm comes through—and it will, usually in late August or early September—those weakened spots just shatter. It’s a one-two punch that’s unique to our area. You combine that with the fact that most homes here have steep, complex roof lines with lots of valleys and dormers, and you’ve got a recipe where the wind just funnels right up under the edges and does its damage before you even hear the thunder.
