Ice dam risk in Payson, AZ

Ice dams in Payson, AZ: how often

1.0 dam days a winter

Almost never. An ordinary house in Payson sees 1.0 day a winter when an ice dam can form, because snow rarely stays on a roof long enough below freezing.

Payson averages 19 inches of snow a year and about 5 days with snow on the ground. Too little lies on the roof for long. The conditions that make a dam need all three at once: snow, cold at the eave and heat above it.

  1. Nothing for ice dams. If you are buying here and an inspector mentions water at the eaves, ask what they saw: it is far more likely a gutter, flashing or drip-edge problem than ice.

Snowy places are not always the worst: why snowfall misleads.
