Best Gable Attic Fan

Attics are perhaps the most forgotten spaces. I barely remember them until I have something to store or something that I want to retrieve. We can all relate when I say it is usually a disappointment to get in there and find the moisture buildup has destroyed some of the items we stored.

It could worsen and compromise your roof’s integrity and eventually the entire structure of the home. As such, it is critical to ensure that the attic is well ventilated to prevent damaging moisture buildup.

This calls for acquiring a gable attic fan which may not be a walk in the park. In this review, you will find the best gable attic fans for your homes.

You may be one of the individuals who has had to withstand the blazing heat in your attic, especially in the summer. The heat may have destroyed some parts of the attic even when you put all the proper insulation, and you have recently realized that it is the lack of a gable attic fan that is the problem in your attic.

You want to purchase the gable attic fan but have some points that you do not understand. Well, you do not have to worry because this guide will answer some of your queries. 

What is a Gable Attic Fan, and How Does It Work?

Gable attic fans are ventilation fans installed on the roof. The installation is done vertically against the gable vent. Gable attic fans can be solar-powered, hardwired into the home’s electrical system, or plugged into standard 120-volt outlets.

The functioning of the gable attic fan is pretty easy. Most gable attic fans (and all those as mentioned above) are automatic. Therefore, when the attic reaches high temperatures, it will turn on and begin bowing out the attic air and moisture.

In the process, the attic fans will pull in fresh air leaving your attic free of moisture and undesirable heat. The gable attic fan usually turns off after the attic temperature reached the desired level.

How Do I Install a Gable Attic Fan?

In the reviews above, there was the constant mention of some of the gable attic fans being easy to install while others are quite hard. You may need the services of a professional.

However, this part of the guide is for those willing to give it a hand and stretch their limits. It is also useful for homeowners who may frequently complain about noise and vibrations. While some of the gable attic fans may naturally have noise, it may be an installation problem. 

The first thing that you should note when installing your gable attic fan is that you need to use sound-dampening materials during the installation to reduce or prevent the loud noise.

Some of the materials you could use include but are not limited to rubber mounts and rubber washers on the screws, which work magic to reduce (absorbing) the vibrations.

The next step is installing the gable attic fan on plywood which is followed by the electrical work. The fans that are easy to install will be mostly plugged and play.

However, the others will require some electrical work which you can follow the manufacturer’s instructions. As always, if you shy away from doing electrical work, you can engage a professional’s services.

What are the Benefits of a Gable Attic Fan?

If I were to purchase a gable attic fan for the first time, I would be all over the internet and shops that deal in these fans looking for the benefits of installing a gable attic fan.

Believe me when I say that you will reap a lot of benefits from having this fan in your attic that you initially thought was not possible. Let’s get started on the benefits!

We are always told not to judge a book by its cover, but we are human and cannot help it. Therefore, I would like to start this first benefit by asking you what you think any time you pass over a house and see that it has a faded roof. Some may argue that they do not even notice the roof but just imagine that you noticed it.

A faded roof is less appealing, especially to individuals who are crazy about aesthetics and appearances. It creates the notion of a home that is not well taken care of and perhaps owners who have little interest in maintenance. Gable attic fans can help in preventing this fading of the roof and its premature aging.

Roofing shingles are an indirect product of crude oil as they are made from asphalt. When the roof heats up, it works as if it is cooking up the shingles on the roof, which leads to the faded coloring of the roof, a sign of premature aging.

However, when there is a gable attic fan, the roofing shingles will barely heat up to excessive levels, leading to a prolonged life for the roof without exhibiting faded coloring signs. 

We can all agree that a cool house is a comfortable house, and you risk the loss of these two elements if you do not have a gable attic fan in your space. Having a hot attic does not only mean that the attic area will be hot, but it will lead to the alteration of temperatures for the entire house.

The heat that the attic retains during hot days is the same as the heat that would be in a car with its windows closed on any hot day- it is unbearable! The heat then transfers to the interior of the home even when the sun has gone down.

This will keep the occupants uncomfortable, necessitating the acquisition of a gable attic fan to prevent this downward transfer of heat. Here, it is possible to argue that the air conditioner in your home will aid in regulating temperatures.

However, with the high amounts of heat, it will be forced to work harder, which increases the air conditioning costs. It may also reduce the air conditioner’s lifespan, sending you shopping for another one sooner than you had anticipated. Instead of going through all this trouble, why don’t you just acquire a gable attic fan?

Attic mold is dangerous, and one cannot ignore it. It can cause serious health problems to the house occupants as its circulation throughout the house from the attic is inevitable.

It can also cause massive damage and structural deterioration to the roof. Attics are usually prone to the growth of mold as they provide the most appropriate conditions for its growth- darkness, moisture, and wood, which is the source of food.

I am sure that all of us would dread such a situation, so you should get a gable attic fan. It helps to ventilate the attic and reduce moisture availability, preventing the growth of the molds in the attic. 

A few years ago, I had a case of ice damming, although it was not severe, and I would not wish a repeat of the same. Those of you who have had similar experiences know that the ice dams tear off gutters, loosen shingles leading to water leaking into the house.

After such an episode, it is almost impossible not to incur the costs of repainting the house and renovating the ceilings. If I had known that a gable attic fan would save me from this trouble, I would have purchased it instantly, and this is one of the benefits that I don’t want you to miss out on.

Poor ventilation of the attic can lead to snow melting instances on the roof from the hot air leaking into the attic. The re-freezing of this melted snow is a recipe for disaster. It causes the formation of the ice dam and inhibits effective roof drainage causing all the damage mentioned at the beginning of this benefit.

Factors to Consider While Purchasing the Best Gable Attic Fan

I have seen so many people ask about the factors they should consider before purchasing their gable attic fans. While it may seem like a monotonous question, I always encourage individuals to seek answers even if they have purchased the equipment before because of their evolving needs and the evolving manufacturer designs in the market.

As such, this section provides some of the factors that you should consider if you are currently shopping for a gabble attic fan.


The first factor that I like talking about is the price. You can want to have the best gable attic fan in the world or even a custom-made one. However, if the price does not meet your budget, you will be in for the biggest shock and disappointment of your life.

 Thus, always start by asking yourself how much I plan to spend on a gable attic fan/ you can then shop for the gable attic fans within that price range. 


The other important facet to look into is the CFM rating. This determined the amount of air that the gable attic fan can move in sixty seconds. You do not want a gable attic fan that will move little amounts of air for your space, necessitating the purchase of another one.

Therefore, ensure that the fan’s CFM rating that you select matches the size of the attic. Most manufacturers will help with this as they will inform you of the maximum size of an attic for their particular models.

Carbon Monoxide Hazard

One of the factors that I like to insist on is whether the gable attic fan will be a carbon monoxide hazard to your space. The question at this point is how carbon monoxide fits into the gable attic puzzle.

Well, it will not fit if you do not have natural gas-burning appliances. However, if you have appliances such as a gas-fired water furnace without enough venting in the attic, you may want to read on.

Less venting leads to the lack of makeup air which may cause the fan to suck out the home’s interior air that may cause malfunctioning to the gas-burning appliances. The appliances will then exhaust their fumes into the home rather than on the outside, causing carbon monoxide poisoning.

You should, therefore, always ensure that the venting requirements and standards in your house align with the attic fan that you plan to purchase for the prevention of such incidences.
