Venting a Bathroom fan into the Attic or Soffit and Why It Is So Important
When it comes to a venting bathroom fan into the attic or the soffit many homeowners are simply not quite sure which really is the best option.
To make matters a little more confusing, builders do tend to have slightly different opinions on the issue as well!
Why Bathroom Fan Ventilation is So Important
Most of us do not need to be told just why venting a bathroom fan properly is so important.
The bathroom exhaust fan is designed to pull all of the moist, unpleasant smelling air out the space to make it a dry, pleasant place to be but all of the nasty air does have to go somewhere!
If a bathroom fan is not vented properly it can lead to real trouble.
Often a homeowner who is planning to have a new bathroom exhaust fan installed has a few options – vent it through the roof, usually via the attic of vent or through the soffit, a vent in the roof itself or take a different tout and find a way to vent the fan directly through the wall to the outside.
The Pros of Venting a Bathroom Fan into the Attic or Soffit
If the bathroom that a fan is being installed in is on the upper level of a home then venting it right into the attic makes sense in terms of ease as all that is really needed is a hole cut into the ceiling and then piping to vent the air through the attic and on to the great outdoors.
Doing this means that the visible outside structure of the house really does not change, something that is very important to some very house proud homeowners, not that you can blame them for that either!
It is also usually less expensive if you choose to commission a contractor to do the work for you than a vent fitted into the wall.
The Cons of Venting a Bathroom Fan into the Attic or Soffit
There are some definite downsides to the idea of venting a bathroom exhaust fan into the roof at all but many of them do directly relate to the quality of the installation job.
If a fan is vented well then running piping from the fan exhaust itself through the attic and on to the outside should be a system that works very well.
However all to often the job is not done correctly and there are gaps in the piping,or at the connections to the fan and the outside vent the the most air may be escaping into the attic all the time.
The result is often that over time the excessive amounts of moisture can permanently damage the structure of the home for good as damp, mold and mildew can form and begin to eat away at roof beams, the attic floor, windows in the attic or even the supporting walls themselves.
If however you take the time to find a great contractor to install your new exhaust fan many of these problems should be avoided and you won’t regret the decision you made on venting a bathroom fan into the attic or soffit.
