Ice dam risk in Pea Ridge, AR
How often ice dams form in Pea Ridge
1.2 dam days a winter
Low risk. On an ordinary house in Pea Ridge, conditions for an ice dam come on about 1.2 days in a normal winter, mostly in January and February.
Pea Ridge averages 10 inches of snow a year and about 6 days with snow on the ground. Most of it comes and goes within a few days. 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 Pea Ridge
| Attic | Dam days | Risk |
|---|---|---|
| Air-sealed and well insulated | 1.0 | Low |
| Typical, some insulation, not air-sealed | 1.2 | Low |
| Older or poorly insulated, warm attic | 1.5 | Low |
The attic matters less in Pea Ridge than in colder towns: there are only 0.2 days a winter between a typical attic and a sealed one.
Preventing ice dams on a Pea Ridge roof
- Check the gutters before the first snow and clear them, so meltwater has somewhere to go. If you see icicles thicker than a finger along the eave after a storm, that is the early sign to look at the attic.
Snowy places are not always the worst: why snowfall misleads.

Where these numbers come from
NOAA 1991–2020 climate normals from Bentonville 4 S, 10.1 miles from Pea Ridge. 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.
