Ice dam risk in Mustang, OK

Will your roof get ice dams in Mustang, OK?

0.8 dam days a winter

Almost never. An ordinary house in Mustang sees 0.8 days a winter when an ice dam can form, because snow rarely stays on a roof long enough below freezing.

Mustang averages 7 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.

Do you need to do anything in Mustang?

  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.

Where these numbers come from

NOAA 1991–2020 climate normals from Oklahoma Cy Will Rogers World, 7.0 miles from Mustang. A dam day is a day with snow on the roof and freezing at the eave while heat or sun melts the snow above it. This describes a normal winter, not this one.
