Snow load, ice dams, and freeze-thaw at flashing points
Flagstaff roofs carry real snow load through the winter, and ice dams form when heat escaping the attic melts snow that refreezes at the eaves, backing water up under shingles or metal panels. Repeated freeze-thaw cycles work on flashing at chimneys, valleys, and penetrations, opening small gaps that let water in over a season or two. Most homes here are built pitched for exactly this reason — a low-slope roof in Flagstaff has a much harder time shedding snow.
Architectural shingle, standing-seam metal, and Class A materials
We install and repair architectural shingle and standing-seam metal roofing, both of which perform well under snow load and handle the freeze-thaw cycle better than lower-grade materials. Given Flagstaff's wildfire exposure, we install Class A fire-rated roofing materials where that matters to the property. We also clear and address the buildup of Ponderosa pine needles and debris that collects in valleys and gutters and holds moisture against the roof.
What to expect from a Flagstaff inspection
We check flashing at chimneys, valleys, and vent penetrations for freeze-thaw damage, look for ice-dam staining at the eaves, and check for pine debris buildup that's trapping moisture. You get a straight read on what's holding up and what needs attention before the next winter, without being sold a Phoenix-style roofing approach that isn't built for this elevation.
