Before we discuss the differences, let us first take a look at some of the similarities between gable mount and roof-mounted attic fans. This will help you to better understand what they have in common. Below are some of the similarities:

1. Attic Ventilation

The primary purpose of the roof-mounted and gable attic fan is to provide proper ventilation for your attic. This is extremely important, as a well-ventilated attic can help to keep your home cooler and prevent the build-up of moisture and excess heat. Either type of attic exhaust fan will be effective in ventilating your attic.

2. Cooling Effect

Another similarity between these two types of attic fans is that they can both help to keep your attic cool. By circulating the air, they can remove the hot air that builds up in your attic, and replace it with cooler air from outside. This can help to keep your home cooler overall with proper attic ventilation.

3. Prevent Moisture Build-up

Both types of attic fans can help to prevent the build-up of moisture in your attic. This is important, as too much moisture can lead to the growth of mold and mildew, which can be harmful to your health. 

Through the circulation of air conditioning, these fans can assist in removing moisture that may be present in your attic.

4. Keep Your Roof in Good Condition

In addition, these two types of fans can both assist in maintaining the health of your roof. They help prevent the build-up of heat and moisture on your roof, which can lead to premature deterioration.

5. Energy Efficient

Roof-mounted and gable fan is both energy-efficient, as they require very little electricity to operate. This is good for the environment, as well as your wallet.

6. Electrical Connection

The gable-mounted and roof-mounted attic cooler will need to be connected to a power source in order to operate. In most cases, this will be a standard household electrical outlet. 

Some models of attic fans may come with a built-in solar panel, which can help to reduce the cost of operating the fan. 

Solar attic fans are becoming increasingly popular, as they are environmentally friendly and can help to save you money on your energy bill. You can choose solar powered attic fan according to your specific needs and preferences.

7. Maintenance

For both types of attic fans, basic maintenance is necessary to ensure that they remain in good working order. This includes things like cleaning the blades and making sure that the electrical connection is secure.

After taking a look at some of the similarities between these two types of attic fans, let us now take a look at some of the key differences. 

These will help you to better understand how they differ from one another, and what type of fan may be right for your needs. Below are some of the main differences between gable-mounted and roof-mounted attic fans.

1. Mounting Location

The biggest difference between these two types of fans is the location where they are mounted. 

As the name implies, gable-mounted attic fans are installed in the gable of your home. This is the triangular space at the end of your roofline. Roof-mounted attic fans, on the other hand, are installed on the roof itself.

2. Aesthetics

Another difference between these two types of attic fans is the aesthetics. Gable-mounted fans are more visible from the outside of your home, as they are installed in the gable. Roof-mounted fans are less visible, as they are installed on the roof itself.

3. Installation

When it comes to installation, gable-mounted fans are generally easier to install than roof-mounted fans. This is because they do not require any modification to your roof. On the other hand, roof-mounted fans will require you to cut a hole in the roof in order to install them, which can be more challenging.

4. Size

Gable-mounted attic fans are generally larger than roof-mounted fans. This means that they are capable of moving more air, which can be beneficial if you have larger attic space. 

However, it is worth noting that the size of the fan is not the only factor that determines its effectiveness. The blade design and motor are also important factors to consider.

5. Coverage

Another difference between these two types of attic fans is the coverage. Gable-mounted attic fans generally provide more coverage than roof-mounted fans. 

This is because they are larger and are mounted in the gable, which provides better airflow. Roof-mounted fans, on the other hand, are limited by their size and location.

6. Performance

In general, gable-mounted attic fans tend to perform better than roof-mounted fans. This is due to their larger size and better location for airflow. 

However, this is not always the case, as the performance of the fan also depends on the quality of the product. When choosing the best attic fan, it is important to consider the quality of the product, as well as the reputation of the manufacturer.

How Does the Gable Mounted Attic Fan Work?

When the gable-mounted fan is turned on, the blades begin to spin. This produces a wind tunnel effect, which pulls hot air out of the attic and pushes it outside. The attic will remain cool, which may prevent heat damage to your home.

How Does the Roof Mounted Attic Fan Work?

Roof-mounted fan works in a similar way to the gable-mounted attic fan. The fan circulates and pushes the hot and humid air from your attic out of the house’s upper levels. As a result, hot, stale air will not accumulate under your roof.
