Attic Exhaust Fans
Mounting Attic Exhaust Fans
Attic exhaust fans mount in the gable end or on the roof itself, just below the ridge or peak. Roof-mounted fans or ventilators are the most effective type. They require that the shingles be removed and a round hole be cut into the roof. In repairing the fan, the fan may have to be removed.
Roof pitch
The pitch of the roof will have an impact on the difficulty
and labor involved.
Electrically powered attic fans are usually equipped with a thermostat that turns on the fan when the attic temperature reaches a certain point and shuts off the fan after the attic cools.
be aware that building codes, such as the National Electrical Code�, set basic standards regarding the type of devices and wiring used, as well as appropriate locations. Check with your local electrical or building inspection office to see if a permit is required if a replacement fan is needed.
