Ice dam risk in Winfield, KS
Will your roof get ice dams in Winfield, KS?
2.0 dam days a winter
Low risk. On an ordinary house in Winfield, conditions for an ice dam come on about 2.0 days in a normal winter, mostly in January and December.
Winfield averages 9 inches of snow a year and about 9 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 Winfield
| Attic | Dam days | Risk |
|---|---|---|
| Air-sealed and well insulated | 1.5 | Low |
| Typical, some insulation, not air-sealed | 2.0 | Low |
| Older or poorly insulated, warm attic | 2.6 | Low |
The attic matters less in Winfield than in colder towns: there are only 0.5 days a winter between a typical attic and a sealed one.
Preventing ice dams on a Winfield 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.
