Ice dam risk in Lompoc, CA
Will your roof get ice dams in Lompoc, CA?
0.0 dam days a winter
Almost never. An ordinary house in Lompoc sees 0.0 days a winter when an ice dam can form, because snow rarely stays on a roof long enough below freezing.
Lompoc averages 0 inches of snow a year and about 0 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 Lompoc?
- 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.
