Phoenix Flashing Hotspots
- !Stucco Reglet Cracking: Extreme thermal shifts pull counterflashing out of stucco grooves.
- !Chimney Cricket Leaks: Large desert chimneys lacking diversion crickets catch standing rainwater.
- !Valley Silt Overflow: Caliche mud dams redirecting water under adjacent clay tiles.
Why Topical Caulking Fails in the Sonoran Desert
Many handyman fixes involve smearing silicone or black roofing tar over flashing joints. Under Phoenix's relentless summer sun, caulking shrinks, cracks, and pulls away within months, trapping water behind the metal and rotting structural fascia and rafters.
Permanent repair requires removing adjacent tiles, cutting a clean reglet channel into stucco or masonry, and mechanically fastening heavy-gauge step and counter flashing backed by self-adhering high-temp membrane wraps.
