Venting Bathroom Fan into Attic

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

How to Vent a Bathroom Fan through the Roof

The proper way in venting bathroom fan into attic is removing the vent both to the roof wall as well as 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 is able to stop the air from reaching the house whenever the bathroom ventilation is not disabled. The flap also can be functioned as a tool that prevents birds from making nests in the ventilation, which is usually happened.

Bird’s nests stuck in the ventilation will make the bathroom air vent can’t be appropriately functioned. 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, bathroom fan can also be venting through 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 installation of the new duct is needed to set up the bathroom fan, make sure you know the size of the duct that is used for the bathroom fan.
  3. Install the soffit ventilation in the correct spot, and mark the area where the hole is going to 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

Bathroom is one of the biggest places in the house that produces water vapor. When the vapor is stuck, it may cause such issues, like damaging the furniture, mildew, mold, and so on.

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.

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