Why Venting Bathroom Fan into Attic is Important?

There are so many bathroom vents improperly set up in the attics. A poorly ventilated bathroom fan may cause damage to humidity, mold, and other problems. Still, it can be adequately managed by using several essential stages.

Before going any further, it should be known that directly venting the bathroom fan into the attic is something that must be avoided. Even so, a bathroom fan can be vented through the cellar as it ends on the roof or outer edges.

Venting Bathroom Fan into Attic

To get a better understanding of how to vent a bathroom fan correctly, read the explanation below.

How to Vent a Bathroom Fan Through the Roof

The proper way to vent the bathroom fan into the attic is by removing the vent both to the roof wall and the ceiling. Nevertheless, the vent must go outward and be set up with a vent cover. When the air is rushing into the ventilation, the vent cover will have a small flap opening, but it will remain shut at all times.

The flap can stop the air from reaching the house whenever the bathroom ventilation is not disabled. The flap can also function as a tool that prevents birds from making nests in the ventilation usually.

Bird’s nests stuck in the ventilation will make the bathroom air vent can’t function appropriately. When you set up a vent cover on the roof for a dryer, you have to remove a metal panel as it will collect dust and may cause danger.

How to Vent a Bathroom Fan through Soffit

Aside from setting up bathroom ventilation through the attic, a bathroom fan can also be vented through the soffit. Follow the steps below:

  1. Set up the soffit cover in a single direction from the bathroom fan as far as possible.
  2. If the new duct’s installation is needed to set up the bathroom fan, make sure you know the size of the duct used for the bathroom fan.
  3. Install the soffit ventilation in the correct spot, and mark the area where the hole will be drawn.
  4. Attach the ventilation to the cover by taking out the vent shaft to the hole.

How to Vent a Bathroom with No outside Access

The bathroom is one of the biggest places in the house that produces water vapor. When the vapor is stuck, it may cause such issues as damaging the furniture, mildew, mold, etc.

In some cases, a bathroom fan is not being vented to the outside because there is no access. However, it does not necessarily mean that it can’t. A bathroom fan can still be installed by running through the spaces until reaching a soffit, to the attic, and then to the vent or through the closest external wall.

Many ways can be conducted to install ventilation in a bathroom. By venting the bathroom fan into the attic with proper steps and setting up a vent through the soffit, some issues caused by water vapor can be avoided.
