Cobra® Attic Ventilation

Poor Attic Ventilation Can Ruin Your Insulation, Destroy Your Shingles, And Potentially Raise Your Energy Bills!

Proper attic ventilation systems allow a continual flow of outside air through the attic, protecting the efficiency of the insulation and helping to lower temperatures in the living space.

It consists of a balance between air intake (at your eaves or soffits) and air exhaust (at or near your roof ridge).

The U.S. FHA (Federal Housing Administration) recommends a minimum of at least 1 square foot of attic ventilation (both intake and exhaust) for every 300 square feet of attic space.

For example, if your attic is 900 square feet, you need a total of 3 square feet of ventilation. This amount should be divided equally between intake and exhaust ventilation (i.e., 1 1/2 feet of each) to insure proper air flow through the attic.
