Vent Bathroom Fan Through Roof Or Wall

The 2nd bathroom vent drips on the floor and is ruining the ceiling.

Vent bathroom fan through roof or wall. The point of a bathroom exhaust vent or any vent really is to remove hot moist air from the house. The 2 pipes one a 4 master and the other a 3 2nd do not go through the ceiling but into a common box that goes through the roof. I am having a new roof installed and am wondering whether i should connect to the current gable vents or have roof vents installed. If the bathroom has an external wall that wall is usually the best choice and if it s difficult to access the roof over the fan is a good second choice for bathrooms on upper floors.

Venting through a roof vent or exhausting them in the attic could cause moisture problems and rot. Bathroom exhaust venting does not have to exit up through the roof and in fact that s not necessarily even the best termination. Since a bathroom vent fan should run for 10 15 minutes after you finish your shower to remove all the moisture consider a fan that cuts on and off automatically using a moisture sensor or replace the wall switch with a timer. However they re not currently connected.

And while both a roof vent and an overhang vent perform this task there is one big difference. Wiring will be fed from light via a triple pole isolator. It is because of this that many builders tend to advise against this method. Fitting a vent in the wall is easier core drill 4 hole then add vent kit and fan.

The fan will need to be an inline fan with ducting and a grill in the bathroom. This involves running ductwork from the fan usually though an attic and out through the roof. Depending on the location of the bathroom it may be easy to vent the exhaust fan through the roof. And of course a bathroom with a window doesn t require an exhaust vent.

Vent your bath and kitchen exhaust fans through the roof through a special roof hood. The master bathroom and the 2nd bathroom vent through the roof and through the same opening. You should never exhaust a bathroom fan through the soffit vents just for the reason you mentioned. Will be usually fed from light with an triple pole isolator.

In order to accomplish this the roof has to have a hole cut in it. The soffit vents are convective intakes for venting the attic. Having warm moisture laden air from a bath exhaust fan exiting out the soffit will drive moisture into the attic causing all sorts of issues with mould mildew and rot. Approximately 10 and 16 foot runs respectively.

Ideally you should aim for the nearest outlet location to make the vent for your bathroom exhaust fan as short as possible.
