Correcting an improperly installed bathroom fan vent

Tom helped a homeowner with a bathroom fan that was venting moist air into his attic. The fan's vent was installed on the underside of a roof soffit, causing moist air to get sucked up into the attic, which was leading to mold and mildew problems. To correct the situation, Tom moved the vent onto the roof, being careful to flash it properly so there would be no leaks.

Where to Find It?

Bathroom fan vents can be found at most lumberyards and home centers.
