How To Install A Bathroom Exhaust Fan Through The Roof

Installing a bathroom exhaust fan through the roof is a relatively simple task that can be completed in a few hours. However, there are a few essential aspects to consider before beginning the installation process. These include the type of fan, the location of the fan, and the size of the ductwork.

The type of fan you choose will depend on the size of your bathroom and the amount of ventilation you need. For smaller bathrooms, a 50 CFM fan will be sufficient. For larger bathrooms, you may need a 100 CFM fan or even a 150 CFM fan.

The location of the fan is also important. The fan should be installed in the ceiling of the bathroom, as close to the shower or bathtub as possible. This will help to remove moisture from the air and prevent mold and mildew from forming.

The size of the ductwork is also important. The ductwork should be large enough to accommodate the airflow from the fan. For a 50 CFM fan, you will need 3-inch ductwork. For a 100 CFM fan, you will need 4-inch ductwork. For a 150 CFM fan, you will need 6-inch ductwork.

Once you have considered these essential aspects, you can begin the installation process. The following steps will guide you through the process:
