The process is similar to installing an attic fan on a shingle roof, but there are a few additional steps you need to take to ensure the fan is properly secured and weatherproofed.
Step 1: Choose the Right Attic Fan
The first step is to choose the right attic fan for your needs. There are two main types of attic fans:
- Solar-powered attic fans: These fans are powered by the sun, so they don’t require any electricity. They are a good option if you live in an area with a lot of sunlight.
- Electric attic fans: These fans are powered by electricity, so they can be used in any climate. They are typically more powerful than solar-powered fans, but they also cost more to operate.
Once you have chosen the type of attic fan you want, you need to determine the size of the fan you need. The size of the fan will depend on the size of your attic and the amount of ventilation you need.
Step 2: Prepare the Attic
Before you can install the attic fan, you need to prepare the attic. This includes clearing away any insulation or other obstacles that may be in the way of the fan. You also need to make sure that the attic is properly ventilated. If there is not enough ventilation, the attic fan will not be able to effectively remove heat and moisture from the attic.
Step 3: Install the Attic Fan
Once the attic is prepared, you can install the attic fan. The installation process will vary depending on the type of fan you have chosen. However, there are some general steps that are common to most attic fan installations:
1. Cut a hole in the roof: You will need to cut a hole in the roof for the attic fan. The size of the hole will depend on the size of the fan.
2. Install the flashing: Flashing is a material that is used to weatherproof the hole in the roof. It is important to install the flashing properly to prevent leaks.
3. Mount the attic fan: Once the flashing is installed, you can mount the attic fan to the roof.
4. Connect the attic fan to the power supply: If you are installing an electric attic fan, you will need to connect it to the power supply.
5. Insulate around the attic fan: Once the attic fan is installed, you need to insulate around it to prevent heat loss.
Step 4: Test the Attic Fan
Once the attic fan is installed, you need to test it to make sure that it is working properly. Turn on the fan and make sure that it is blowing air out of the attic. You should also check to make sure that there are no leaks around the fan.
Step 5: Maintain the Attic Fan
Attic fans require very little maintenance. However, you should inspect the fan regularly to make sure that it is clean and free of debris. You should also lubricate the fan’s bearings every few years.
Additional Tips for Installing an Attic Fan on a Metal Roof
- Use a metal roof sealant: When you install the flashing around the attic fan, be sure to use a metal roof sealant to help prevent leaks.
- Install the attic fan in a sunny location: If you are installing a solar-powered attic fan, be sure to install it in a sunny location where it will receive plenty of sunlight.
- Consider installing a thermostat: A thermostat can help you control the operation of the attic fan. This can help you save energy and improve the comfort of your home.

Installing an attic fan can provide a number of benefits, including:
- Reduced energy bills: An attic fan can help to reduce your energy bills by lowering the temperature in your attic. This can make your air conditioner work less hard, which can save you money on your energy bills.

- Reduced moisture: An attic fan can help to reduce moisture in your attic, which can help to prevent mold and mildew growth.
- Longer roof life: An attic fan can help to extend the life of your roof by reducing the amount of heat and moisture that is trapped in the attic.
