Do You Need An Attic Fan If You Have Roof Vents?
There are a few things to consider when deciding whether or not you need an attic fan if you have roof vents. According to HVAC SEER, an attic fan can be detrimental in a properly designed attic.
The purpose of an attic fan is to blow hot air out of the attic, but the fan can interfere with the natural process of roofing vents. If you have roof vents, they are there to allow hot air to escape.
The attic fan can actually disrupt this process and cause the attic to become hotter, which can also cause health problems. According to LiveScience, it is important to place the attic fan in the correct location.
If you have a master suite on the second floor and the attic fan is placed in front of an open window, there are negative effects that people inside the home can feel.
The outlet from an attic fan should be placed away from windows and doors to prevent contamination of incoming air and leaks out of the home when the fan is not running.
Is A Roof Fan Worth It?
There are several reasons why installing a roof fan in your attic can be beneficial, even if your roof already has ridge vents and other forms of ventilation. For one, roof fans can help to blow hot, humid air out of the attic, which can improve the overall comfort level of your home.
Additionally, attic ventilation fans are often quite energy-efficient in their own operation, meaning that they can help save you money on your energy bills.
It is also important to note, however, that while an attic fan can be beneficial, it should not be used to replace the function of your roof vents and other forms of ventilation.
Many homeowners attempt to install attic fans without a permit, which can have detrimental effects on their homes. Improper installation or installation of an attic fan without having a proper permit can cause the fan to become damaged.
When this happens, a homeowner could experience a variety of problems, from structural damage that could leave home in need of repairs because the frame is weakened by excessive weight on it.
In more extreme situations, improper installation could cause the entire roof to collapse. If you are interested in an attic fan, check the local codes before starting any home improvement process.
How Do You Vent An Extractor Fan Through The Roof?
The process of installing an extractor fan through the roof is pretty simple. First, you need to find the right location on the roof. Keep it close to the fan location, so you don’t have to run any wiring or cables up there. Next, drill a hole in the roof.
Make sure the hole is big enough so that the fan can fit through it, and leave the drill bit sticking through the roof so you can find it later.
Once you have the hole ready, it’s time to get up on the roof and start cutting. Use a jigsaw or a reciprocating saw to cut a 4-in. hole in the roof. Ensure the hole is close to the fan location so the incoming air can flow easily.
Once the hole is cut, install the fan and enjoy your much-needed airflow without having to worry about the noise or the dust.
