Ice dam risk in Kaysville, UT
Ice dams in Kaysville, UT: how often
6.1 dam days a winter
Moderate risk. On an ordinary house in Kaysville, conditions for an ice dam come on about 6.1 days in a normal winter, mostly in January and December.
Kaysville averages 50 inches of snow a year and about 25 days with snow on the ground. Plenty falls, but it tends to melt off between storms, which keeps the count lower than the snowfall suggests. That gap is why snowfall alone misleads.
What your attic does to that number in Kaysville

|---|---|---|
| Air-sealed and well insulated | 4.5 | Low |
| Typical, some insulation, not air-sealed | 6.1 | Moderate |
| Older or poorly insulated, warm attic | 8.1 | Moderate |
The attic matters less in Kaysville than in colder towns: there are only 1.6 days a winter between a typical attic and a sealed one.

Where these numbers come from
NOAA 1991–2020 climate normals from Farmington 3 NW, 0.9 miles from Kaysville. 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.
- Snow-on-the-ground counts come from a second, nearby station, because the closest one does not record them.
