Ice dam risk in Sebastian, FL

How often ice dams form in Sebastian

0.0 dam days a winter

Almost never. An ordinary house in Sebastian sees 0.0 days a winter when an ice dam can form, because snow rarely stays on a roof long enough below freezing.

Sebastian 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 Sebastian?

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.
