Ventilated Cold Attic
This roof design is used in buildings with attic spaces above an insulated ceiling to prevent ice dams and roof leaks. The ventilated cold attic design with vents in the eves and gables allows air movement through the attic to keep the roof deck at the same temperature as the outside air. This prevents snow melting when the outside temperature is below freezing.
Ventilated Cold Roof
This roof design is used in buildings with vaulted or cathedral ceilings to prevent ice dams and roof leaks. The ventilated cold roof design with vents in the eves, rakes, and ridge allows air movement through an open grid or frame above the insulation and below the roof deck. The air movement keeps the roof at the same temperature as the outside air, preventing snow melting when the outside temperature is below freezing.
This is the roof that we designed for the Kuykendall house in Steamboat Springs. The cold roof is functioning well, with no icicles or buildup of ice. The structure of the roof is designed to support the heavy snow load that this house often receives. Snow guards can be used to prevent sliding on warm days.
This is another cold roof that we designed. The roof shows no signs of ice buildup even after a period of very heavy snow and cold temperatures.
