And in some unique cases if the cable is run close enough together can eliminate the ice dams from forming in a specific are. However, because ice dams form when heat loss escapes the home, unless the heat loss is stopped ice dams will likely form. Want to chat about heat lines on your roof? Call IDSAFE # 612-460-0474.
