The Top 5 Best Rated Roof Mounted Attic Fans in 2020
Here is my list of the best roof mounted attic fans. These fans are installed on the roof to automatically remove moisture and heat. If you want to read my full reviews, keep scrolling.
What are Roof Mounted Attic Fans?
A roof mounted attic fan rests on top of the roof and helps regulate a property’s temperature by removing hot air. In general, this type of attic fan is accompanied by a sturdy base, which is made of sheet metal or plastic. The attic fan sits on top of this base and works similar to a traditional mounting plate.
The fan has to be installed effectively to ensure it can access the attic and remove hot air.
A roof mounted attic fan is often seen as a cost-effective alternative to the installation of the ridge & soffit passive vents. Since, the attic is generally a separate part of the house, it tends to heat up faster as the air moves upwards. As a result, a roof mounted attic fan helps keep the temperature down.

For the fan to work properly, it is equipped with a thermostat to automate when the fan turns on/off. When the fan is on, it will continue to eliminate hot air from the attic.
It’s important to note the fan works in unison with passive vents because that’s where it pulls in outside air. When the fan is doing its job, the hot air will be replaced with cooler air to regulate the house’s temperature. For the cool air to enter, there must be enough passive venting for the attic fan to work properly. The attic fan spins to help remove hot air, while the cool air comes through the vents. This can be advantageous when it comes to keeping the attic moisture-free and comfortable.
What are the Benefits of Roof Mounted Attic Fans?
Roof mounted attic fans offer a number of advantages and can be a real difference maker for homeowners.
It’s important to sit down and understand these benefits and why investing in a good attic fan is essential.
The benefits include:
- Regulates Property’s Temperature
- Helps Protect the Roofing Material(s)
- Reduces Utility Bills
- Consistent Results

How to Install a Roof Mounted Attic Fan
Installing a roof mounted attic fan requires attention to detail and the ability to find a good spot to set everything up.
Before beginning, it’s highly recommended to understand the attic’s layout, where the fan will be mounted, and how it’s going to be mounted. This information is essential in ensuring the process is smooth, safe, and in line with what the house requires.
Once the roof has been inspected, it’s time to work on creating a measured vent hole near the top of the roof. A vent hole is necessary because this is where the fan is going to be mounted using a plastic or metal base.
After the fan has been mounted, customized sheets of shingle can be placed near the base flashing. This secures everything into place and ensures the fan lasts for a long time.
It’s important to patiently work through the various attic fan installation steps and make sure everything works as intended. This includes testing whether or not the attic fan is functioning after it’s been installed.
How to Pick the Best Roof Mounted Attic Fan?
The wiring is the foundation of a strong, efficient attic fan.
If the wiring isn’t correctly set up, this can take away from the fan’s performance and can hinder how long it lasts too. As a result, it’s important to analyze how the attic fan is designed and what the wiring is going to look like once the attic fan installation is complete.
In some cases, the fan is hard-wired directly into the main electrical supply. However, other options offer a straightforward socket-based solution if there’s one located in the attic. Of course, solar attic fans are a great option for those seeking an eco-friendly fan. Solar powered attic fans run continuously when the sun is out so the only cost is the initial purchase.

Remember, when buying a new attic fan, it’s best to consider the measurements and how the wiring will fit. Any issues in this regard can lead to electrical-based issues over the long run.
Does it have an adjustable attic fan thermostat for regulating temperature? A high-quality fan is going to include user-friendly settings to ensure the temperature is properly regulated.
These adjustments should take no more than a few seconds to implement. Once everything is ready to go, the right attic fan handles the temperature on its own. Whenever you want to make adjustments, you can play around with the settings and customize the fan’s performance.
When the weather begins to change, you want to have this option in hand. An attic fan thermostat is essential in most places.

The average roof mounted attic fan comes with an on/off switch and can easily be controlled by the homeowner. If necessary, the fan should also offer an automated solution to kick in whenever the temperature hits a specific number. For most homeowners, it’s easier to go with the automated attic fan, as it’s simple, efficient, and safe at the same time.
Before doing anything else, you should take the time to measure your attic and see where the roof mounted fan is going to be installed. Measurements are essential because it allows you to know whether or not the fan can keep up with your property’s needs.
Certain attic fans don’t cover enough space to be worthwhile. This means some of the air gets removed while the rest remains inside the attic. This is a significant issue because it ruins the house’s temperature and leads to awful results.
To know the fan’s output, look at what the product description says. What is its coverage area? Does it go up to 2,000 square feet? Is this enough for your house?
Ask these questions before spending hard-earned money on a new roof mounted attic fan.
To measure correctly, take the length and multiply it by the width.

When a fan isn’t durable, you’re not going to enjoy its presence for too long.
In general, the best roof mounted attic fans are made of aluminum and/or steel. These materials are dependable, efficient, and work well in all weather conditions. This makes it easier to rely on them when it comes to your property’s setup.
Other materials are riskier and may end up making too much noise.
Along with having a steel and/or aluminum-based build, the fan should also include a comprehensive finish. This means it shouldn’t have hanging parts, loose components, or anything that’s out of place. When a fan isn’t built properly, it can start to breakdown and age quickly.
How long does it take to set up the new attic fan?
There is nothing worse than buying a new attic fan, taking it out of the box, and realizing you have to buy separate parts to make it work. This is annoying, unnecessary, and doesn’t happen with the best brands.
Look for the market leaders, so you don’t have to struggle with the installation process. A high-quality roof mounted attic vent fan is going to come with the necessary components and will be a breeze to set up.
Take a look at what’s required and how the fan is going to be mounted. Having this information can make all the difference when it’s time to compare models and make a decision.
How Do You Inspect Attic Fans?
#1. Will It Turn On?
Locate the thermostat (small metal box) usually mounted on a rafter or truss next to the fan in the attic. Turn the temperature knob so it is below the current attic temperature. You can also use a heat gun, hair dryer, or lamp to heat up the thermostat if the attic is cold.
#2. Turn The Blades
If the attic fan doesn't turn on, try turning the fan blades. If the blades won't turn, you may have a seized motor.
#3. Operation Quality
If the the attic fan turns on, are their any weird noises? Does it run smoothly? Can you feel air flow or is it very weak? The fan screen or louvers should not be blocked with debris impeding air flow.
#4. Water Stains
A common problem with attic fans are leaks. Are there any signs of water leaks around the fan on the roof sheathing?
How Are Roof Mounted Attic Exhaust Fans Different From Other Fans?
Ventilating the attic is all about finding the right fan, installing it correctly, and making sure the settings are customized for your property.
While most people lean towards roof mounted attic fans, this isn’t the only option available to you. A gable-mounted attic exhaust fan is also a potential option for those wanting to steer clear of a roof-mounted alternative.
Here’s a detailed comparison of both options and how they work.
While both types of attic fans do the same job, they are completely different in how they’re set up. A roof-mounted version is set up near a vent hole and is close to the top of the roof. However, a gable-mounted version is installed inside the attic.
Remember, “gable” is the triangular part of the wall.
This means the design is reliant on setting up in that portion of the attic.
These subtle differences in design can play a role in a homeowner’s decision. Some want the fan inside, while others don’t mind it close to the top of the roof. This is going to vary from person to person.
With cooling capacity, the attention goes to how well it “cools” the attic on a per-minute basis. The measurement is called cubic feet per minute and is important in understanding how both types work.
A gable fan is often used for larger properties due to its size, while a roof-mounted version does well in compact spaces. This isn’t a steadfast rule but it’s a general idea to keep in mind.

Roof mounted attic fans are equipped with solar panels and other similar components. This makes it easier to personalize the source of power for your attic fan.
On the other hand, gable fans rarely come equipped with such options. This has to do with where they are installed, as most of them aren’t exposed to the sun.
A gable attic fan installation is time-consuming. The average property doesn’t come equipped with a separate gable vent, which means that’s an additional step you have to complete.
Since most property owners don’t want to struggle with the installation process, they prefer to go with a high-quality roof mounted attic fan. It’s easier to set up, doesn’t have too many components, and delivers consistent results throughout the year.
From a maintenance perspective, both fans can be challenging depending on which one you buy. A well-reviewed attic vent fan can last for a decade as long as it’s properly maintained.
