Balanced attic ventilation involves intake and exhaust to admit fresh air and allow moist air to escape. This prevents mold and mildew growth, which can affect indoor air quality. Moisture buildup in your attic caused by inadequate ventilation can also lead to premature roof deterioration.
In the last segment of this two-part blog, Masters Roofing, a general contractor, explains how to ventilate your attic.
Is there Enough Ventilation in Your Attic?
Most local building codes require ventilating attic spaces. The Federal Housing Administration even suggests a minimum of one square foot of ventilation for every 300 square feet of attic floor space. Attic ventilation, however, should be split between intake and exhaust to regulate air flow.
Ridge Vents
Apart from learning how much ventilation your attic needs, identifying different methods to control air flow is also necessary. Ridge vents, for instance, are ventilation strips that are installed along the ridge line of a home. Before your roof replacement contractor installs this type of vent, a one-inch wide strip of the roof decking is cut along both sides of the ridge to let air movement through the vent.
Soffit Vents
This type of vent allows the circular movement of air, from the soffits to the ridge vent. Insulation baffles should also be installed in the area where the attic floor meets the roof line. This is done to restrict the airflow from the soffit vents.
Gable Vents
With gable vents, air is drawn out of the attic space to prevent moisture from blowing back into the home. They often appear as louvered vents, which are installed in the gable ends.
