Venting Your Bathroom Fan Into the Attic
Proper venting of bathroom fans helps keep excess moisture out of your home. However, a common shortcut for this kind of exhaust fan is to vent it into the attic or a crawl space. This often happens when it would be onerous to vent the fan to the outside, which is the standard practice.
But when such an exhaust fan is vented into an interior space, it can cause moisture to build up inside, potentially leading to mold, rot, or other problems that don’t become apparent until there is an inspection. Homeowners should double check that their bathroom fans are properly vented outside.
