Removing ice dams in gutters is an inevitable fact of living in a cold or snowy region. An ice dam is formed when gutters get clogged with ice and the problem is further compounded by water runoff from the roof being trapped by the dam and rerouted to beneath the shingles and eventually into the house. A temporary fix for an ice dam is fairly simple. Fill up the leg of an old pair of panty hose with calcium chloride ice melter. Put the panty hose on the roof so it will cross the ice dam and overhang into the gutter. The melter will eventually create a channel for the water to flow.
