Ice dam risk in Horizon City, TX
Will your roof get ice dams in Horizon City, TX?
0.1 dam days a winter
Almost never. An ordinary house in Horizon City sees 0.1 days a winter when an ice dam can form, because snow rarely stays on a roof long enough below freezing.
Horizon City averages 3 inches of snow a year and about 1 day 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 Horizon City?
- 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 El Paso International Airport, 14.3 miles from Horizon City. 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.
- The nearest weather station sits at a noticeably different elevation from Horizon City, so the snow figures may run high or low for the town itself.
