Stuck somewhere in the middle, we have the option of connecting your bathroom vent to the soffit of your home.<\/p>\n
If you are curious about venting a bathroom fan through a soffit, know that this is usually not the ideal option. However, there are instances when this is the best thing that you can do. Keep reading to find out when and how to vent a bathroom fan through soffit.<\/p>\n
What Is a Soffit and How Does It Work?<\/h2>\n

<\/p>\n
Soffit is placed on the overhangs of your roof. The underside of this overhang has several names – some call them house eaves while others say rafters. Both sides agree that the name for the bottom with a completed appearance is \u201csoffit,\u201d or \u201ca thing that hangs under.\u201d<\/p>\n
A soffit can be of almost any finishing material, such as wood or fiber cement. What matters more than the material used is its function – a soffit covers the bottom side of your roof overhang.<\/p>\n
The main reason to have a soffit of some kind set up on your roof is for ventilation purposes. Since a soffit would be covering the side underneath your roof, it would become a part of your loft space. As you must know by now, the attic is the warmest portion of your house.<\/p>\n
This is because all the hot air from inside your home gets trapped in the attic. At the same time, your attic becomes increasingly warm thanks to the sun beaming down on it and creating the hottest spot in your house.<\/p>\n
All this accumulated heat must have some way to get out. Without proper ventilation, you are at risk of roof shingles breaking more easily during the summer. In addition, the same heat can cause the creation of ice barriers during winter, which may cause water to leak.<\/p>\n
Higher temperatures in your attic also mean an increase in energy bills when your AC is on during summer. A humid environment is also the main culprit for mold, mildew, and wood rot caused by increased humidity.<\/p>\n
Soffits may be perforated or vented to help air circulate through your attic space and decrease the risk of all the unwanted things mentioned above. In addition, during the hot days of summer, soffits can help your home stay warmer while keeping it less humid during the colder days of winter.<\/p>\n
Soffits also protect the underside of your roof and your deck from the elements. In addition, they can keep harmful moisture and pests such as insects away from your balcony.<\/p>\n
Finally, a nice-looking soffit adds a vital aesthetic component to the overall look of your home. If you are only now installing soffits, pick a material and color that nicely compliments the rest of the exterior of your home and gives it a polished and unique look.

A hole in the roof of your home might lead to leaks and other problems.<\/p>\n Sometimes, connecting your second-floor bathroom to the outside wall can be more trouble than it is worth. That is when venting a bathroom fan through the soffit is your best option.<\/p>\n This option is also attractive because of the shortest possible duct length without too many bends.<\/p>\n By venting to the soffit, you also avoid the risk of back-drafting. If you mount a fan vertically on your bathroom wall<\/a>, it will have to work overtime as it will have to fight against winds coming in from outside. Back-drafting can even suck back inside the humid air you are trying to expel and make your fan work even harder.<\/p>\n By venting your bathroom through a soffit, you are also preserving the integrity of your roof. This can be crucial if your house is old and your roof is not in perfect shape.<\/p>\n Finally, this type of ventilation can be beneficial for room heat preservation. When your bathroom fan is turned off, all the air will stay suspended in the ducts and act as a heat trap. As a result, it will prevent cold air from entering your home. This is particularly useful in colder climates.<\/p>\n The soffit cover does the same thing as its wall-mounted counterpart does. Namely, it is tasked with keeping the outside air outdoors, where it belongs. It can also keep out moisture and small animals such as birds and even prevent them from building nests that can significantly obstruct the airflow.<\/p>\n Modern soffit exhaust covers are spring-loaded, so they automatically snap shut once your bathroom fan is off. Some have a fixed duct size, while others are adjustable to fit both four and six inches wide duct vents.<\/p>\n Check the package carefully and make a note of these measures before you start working.<\/p>\n Photo by Ben Freeman via Flickr<\/a> (CC BY-NC 2.0)<\/p>\n Venting your bathroom through a soffit can be a doable DIY project. Here is what you should pay attention to.<\/p>\n Do not bend the hose when installing the soffit exhaust cover. In general, you want to have the smallest possible amount of bends and curves when installing your vent. Fewer curves mean smoother airflow and better ventilation while also reducing the risk of condensation and problems with moisture and mold.<\/p>\n Pick a vent hose that is of appropriate size – before you commit to installing the vent, make sure that you have done all the necessary measurements. Most importantly, measure the duct size of your bathroom fan.<\/p>\nSome Advantages of Venting a Bathroom Fan Through a Soffit<\/h2>\n
