If you have never used an ice dam melting sock on your roof before, you will search that they give an inexpensive method for removing roof ice dams and improving your home's heating efficiency. Roof ice dams are an annoying source of roof damage, leaks, and heat loss in the winter. The major causes are drip melt from improperly capped warm air vent pipes and poor roof insulation. Laying a ice melt sock onto the roof so it crosses the ice dam and overhangs the gutter, will melt by the snow and ice and create a channel for water to flow down into the gutters or off the roof. If complete properly those ice sickles that form as the snow melts from the edges of the gutters will never appear, they too are a cause of much damage and are dangerous to life and limb.
