Ice dam risk in Mount Juliet, TN
Ice dams in Mount Juliet, TN: how often
0.4 dam days a winter
Almost never. An ordinary house in Mount Juliet sees 0.4 days a winter when an ice dam can form, because snow rarely stays on a roof long enough below freezing.
Mount Juliet averages 5 inches of snow a year and about 3 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 Mount Juliet?
- 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.

NOAA 1991–2020 climate normals from Old Hickory Wfo, 4.4 miles from Mount Juliet. 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.
