Westminster Forensic Weather & Hail Impact Report

You know, living here in Westminster, we’re kind of sitting right in Mother Nature’s crosshairs when it comes to hail. It’s not just bad luck—it’s the geography. We’re nestled right against the foothills, and those mountains act like a giant ramp for spring and summer storms. When the warm, moist air from the plains slams into that cooler air coming down from the Front Range, it forces the clouds to build straight up, fast and violent. That’s how you get those supercell thunderstorms that seem to pop up out of nowhere around April and May, and they’ll just sit there and pound us with hail the size of golf balls or bigger. I’ve seen neighborhoods where the south and west-facing slopes of the roofs look like they’ve been through a war, while the north side is barely scuffed—it’s all about which way the storm is pushing the ice.

And it’s not just the hail, it’s the wind that comes with it. We get these intense downbursts, where the cold air from the storm slams straight down and then fans out across the flat, open areas of the city. There’s nothing to break that wind up, so it hits your roof like a freight train. That combination is the real killer: the hail weakens and bruises the shingles, knocking the protective granules right off, and then the wind comes along and peels those damaged, brittle shingles right up or tears them clean off. We also get those sneaky fall storms in September and October that roll through with straight-line winds of 60 or 70 miles an hour, which is more than enough to lift the corners of a roof that’s already been weakened by a summer of hail. Honestly, if you’ve lived here for more than five years, your roof has probably taken a beating, even if you can’t see it from the ground.
