Scottsdale Forensic Weather & Hail Impact Report

Look, I’ve been replacing roofs out here for over twenty years, and if there’s one thing I tell every homeowner it’s this: Scottsdale sits right in the bullseye of Arizona’s monsoon season. From about mid-June through September, those massive thunderheads build up over the Superstition Mountains and then roll straight across the Valley. The problem isn’t just the rain—it’s the sudden, violent downdrafts that come with them. We get microbursts that can hit 70 or 80 miles an hour, and they’ll peel shingles right off a roof like they’re nothing. And because our homes are often built with that wide, flat architectural style and lots of exposed eaves, there’s just more surface area for the wind to grab onto. It’s not like a steep, traditional pitch that deflects the air; it’s a big, flat sail just waiting for a gust.

Then you’ve got the hail, which is a whole different beast. People think of hail as a Midwest problem, but we get some gnarly hailstorms here, especially in the spring and during those same monsoon bursts. The stones don’t have to be huge—even marble-sized hail, when it’s driven by that 60 mph wind, hits your roof at an angle instead of straight down. That’s the killer. It gets under the edges of the shingles and bruises the matting, which you can’t even see from the ground. You’ll go months without a leak, and then one hot summer day the sun bakes that damaged area, and suddenly you’ve got cracks and granule loss everywhere. The combination of our intense UV rays and that wind-driven hail is a one-two punch that just destroys asphalt shingles faster than almost anywhere else in the country. So when you see a storm rolling in from the east, know that your roof is taking a beating even if it looks fine from the street.
