Vaughan Forensic Weather & Hail Impact Report

Look, I’ve been replacing roofs up here in Vaughan for over twenty years, and I can tell you, we’re sitting right in Mother Nature’s bullseye when it comes to hail. It’s not just bad luck—it’s the geography. We’re nestled right along the eastern edge of the Blue Ridge foothills, and that creates a natural funnel for those violent spring and early summer thunderstorms that build up over the mountains. As that hot, humid air gets shoved up and over the ridges, it collides with the cooler air coming off the Piedmont, and that’s the perfect recipe for those supercell storms that drop golf-ball-sized hail. I’ve seen neighborhoods off of Highway 1 where the south-facing slopes take the brunt of it, while the north side of the same street looks like nothing happened. It’s all about how the wind whips around those hills, and when it does, it drives those ice chunks straight into your shingles at an angle that just shreds them.

And it’s not just the hail—the wind that comes with these systems is a whole other animal. We get these derecho-style straight-line winds, usually in late July and August, that come screaming down the valley with gusts that can easily hit 70 or 80 miles an hour. The problem is, our homes here are often tucked into wooded lots with mature oaks and pines, which sounds nice, but those trees act like wind tunnels, channeling the air right over your roofline and lifting the edges of your shingles like a deck of cards. Once that seal is broken, the next storm just peels them right off. Plus, the constant freeze-thaw cycles we get in the winter—where it’s 50 degrees one day and 15 the next—make the asphalt brittle, so when that first big hail storm of April hits, the granules are already loose. It’s a perfect storm of conditions, and honestly, if you haven’t had a roof inspected after a bad storm, you’re gambling with the one thing that protects everything else you own.
