How to properly vent a bathroom exhaust fan in an attic


By Danny Lipford

Bathroom exhaust fans perform an important function by removing excess moisture from your home. When venting a bathroom exhaust fan, make sure to vent the air to the outside, rather than into your attic where it can cause mold and mildew to form.
Options for venting a bathroom exhaust fan include (best to worst):
Through the roof or an exterior gable wall.
Behind a gable vent.
Behind a soffit vent.
To improve venting and reduce air resistance in the vent pipe:
Keep the run of vent pipe as short and straight as possible.
When possible use smooth metal pipe, rather than flexible ductwork.
