Can ice dams on the roof be prevented?
The preferred method of preventing ice dams in non-cathedral roofs is to properly ventilate and insulate. Energy efficient roofs minimize problems with ice dams because they keep the entire roof cold. There is little difference in temperature between the part of the roof inside the perimeter of the outside walls and the part covering the eves or overhangs. Thus, melting and refreezing is minimized. Insulating to prevent heat leaks and sealing against air leaks between the inside of the building and the attic are the best ways to achieve a cold roof. Its primary purpose, though, is to prevent moisture from condensing in the attic on the underside of the roof decking and dripping down into the insulation. Any warm air that leaks from the inside of the building into the attic carries moisture with it. Sealing the air leaks is usually more effective than increasing the ventilation.
