Ice dam risk in Bixby, OK
Will your roof get ice dams in Bixby, OK?
0.9 dam days a winter
Almost never. An ordinary house in Bixby sees 0.9 days a winter when an ice dam can form, because snow rarely stays on a roof long enough below freezing.
Bixby averages 9 inches of snow a year and about 6 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.
What your attic does to that number in Bixby
| Attic | Dam days | Risk |
|---|---|---|
| Air-sealed and well insulated | 0.8 | Very unlikely |
| Typical, some insulation, not air-sealed | 0.9 | Very unlikely |
| Older or poorly insulated, warm attic | 1.1 | Low |
The attic matters less in Bixby than in colder towns: there are only 0.1 days a winter between a typical attic and a sealed one.
Do you need to do anything in Bixby?
- 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 Tulsa International Airport, 17.5 miles from Bixby. 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.
