An Ice dam is a large formation of Ice that forms behind a typical set of Icecicles. When this Ice melts, the water can gather behind and seep into and under the shingles. Eventually, that water can leak through your ceiling, causing damage and other issues to the roof and interior walls. We here at Dye Home Improvement in Monticello, Monon, and Royal Center want to help you prepare and prevent this issue. Armed with a little more knowledge, you will be ready to conquer the ice, once and for all.
