The snow melt can then refreeze near the end of the roof the eaves forming an ice dam.

Why would you need the volume of an attic.

Warm air in your home rises ultimately reaching your attic. If you don t have an air tight attic the vent may pull warm air up from below increasing the heat in your attic which can cause snow to melt faster near the top of your roof. Improper ventilation can contribute to heat and moisture buildup in the attic and can even increase the temperature in your living space. If you want to heat or cool your attic space calculating its cubic footage is necessary to determine adequate ventilation.

Another effect of improper ventilation is that it may increase cooling energy consumption. Effective ventilation provides year round benefits creating a cooler attic in the summer and a drier attic in the winter. Excessive heat and moisture can cause damage to shingles wood framing ceiling siding paint and wallpaper. However an attic usually doesn t have straight walls.

Warm air holds more moisture than cool air so the moisture we create in our homes from bathing and cooking travels to the attic. How do you know if you re having venting problems. The formula for figuring out the cubic footage of a rectangular solid like the interior of a room is length times width times height. In cold climates the primary purpose of attic or roof ventilation is to maintain a cold roof temperature to control ice dams created by melting snow and to vent moisture that moves from the conditioned space to the attic ventilation acts to bypass the vapour barrier created by most roof membranes.
