A dangerous and damaging ice dam problem can often be solved by installing a perimeter ice melt system, such as the Roof Ice Melt (RIM) system by Bylin Systems retrofitted on this high-country resort lodge. A rooftop heating system installed above the eaves prevents snowmelt from refreezing and creating ice dams and water ponding in roof valleys and at the eaves. The melting and refreezing of ice dams can severely damage roofing materials and gutters and cause water damage and rot inside your roof, insulation, walls, and living space.
