Williamston Forensic Weather & Hail Impact Report

Look, I’ve been replacing roofs in this part of eastern North Carolina for over twenty years, and I can tell you without a doubt that Williamston gets hammered in ways folks inland just don’t see. We sit right in that sweet spot where the coastal plain meets the river basin, and that flat, open terrain gives the wind absolutely nothing to slow it down. When a summer thunderstorm rolls off the Pamlico Sound or pushes up from the Cape Fear region, it can pick up speed like a freight train across those soybean fields. And it’s not just the big hurricanes—though we’ve had our share of those, like Matthew and Florence—it’s those pop-up supercell storms in April and May. They’ll drop golf-ball-sized hail out of a sky that was blue an hour earlier, and that hail hits your shingles at an angle because the wind is already blowing 60 miles an hour. That combination is the worst thing for a roof: the impact bruises the asphalt, and then the wind peels back the edges where the granules have been knocked loose.

The real kicker is how the Roanoke River and the low-lying swamps around us mess with the weather patterns. On a hot, humid afternoon, that moisture gets sucked up into the atmosphere, and when it meets a cold front coming down from the mountains, it explodes right over our heads. We get these intense, localized microbursts—straight-line winds that can hit 80 or 90 miles an hour for just a few minutes, but that’s all it takes to lift a whole section of shingles off a roof deck. I’ve seen brand-new architectural shingles that were rated for 130 mph winds just shredded because the hail had already weakened the sealant. And since our storm season runs from late spring all the way through hurricane season in October, your roof takes hit after hit year after year. It’s not a matter of if, but when, and that’s why I always tell folks here to check their flashing and ridge caps before the first big storm of the year, because once that wind gets under a loose edge, it’s like a zipper opening up the whole roof.
