With a cold roof, the roof temperature stays the same as the temperature of the outside air. Cold roofing prevents the formation of ice dams, which can be a regular hazard with warm roofs. Ice dams are formed when snow melts on the roof and then refreezes on the roof overhang. As more snow melts, the water is caught by the ice dams, causing moisture to seep through the roof into the building, which can lead to structural damage. With cold roofs, as the snow doesn't melt, there is no question of ice dam formation and all the problems that go with it. The traditional cold roof construction consists of a well-ventilated attic space with a pitched roof. Insulation is placed horizontally between the attic joists and the ceiling of the floor below. Any gaps in the ceiling are sealed to keep out moist air from the building.
