Phoenix, AZ storm damage roofing guide
Phoenix's peril is monsoon wind rather than hail, concentrated June through September, when outflow and haboob microbursts produce 60–80 mph gusts across the valley. The city builds to the 2021 IRC with local amendments and a 90 mph wind design speed. Tile is the dominant residential system across much of the valley, and a tile loss is an underlayment question as much as a tile question: broken and slipped tiles are visible from the ground, but the felt beneath a 20-year-old tile roof is usually what fails, and detach-and-reset of sound tile is a separate labour line from tile replacement. Arizona has no matching statute, so discontinued tile profiles have to be documented rather than asserted. Foam and low-slope sections on flat-roof and mixed-roof homes need their own scope.
