Bathroom ventilation is so important that residential building codes require at least one openable window in each bathroom. Many local codes also require a bathroom exhaust fan.
A bathroom exhaust fan removes moisture vapors generated from bathing and other activities as well as keeping the bathroom fresh. Without the proper bathroom ventilation moisture condensation can do serious damage to drywall, wallpaper, window coverings, and cabinetry and may lead to serious mold issues. A bathroom exhaust fan keeps the bathroom dry and odor-free. Models are available that mount in the ceiling, a wall or the window, but all must vent to the outside.
NOTE: Make sure your bathroom fans exhaust to the outside, not into an attic. Releasing moisture from bathing that regularly collects on attic surfaces will eventually lead to mold issues and possible structural damage. Moisture weakens the wood by slowly destroying individual wood fibers, layer by layer. Attic moisture can also destroy or retard the performance of an attic’s insulation.
The most common option for bathroom exhaust fan venting is the ceiling to wall venting option. The second most common is the roof vent installation. The third most common is probably the vertical wall installation. Bathroom exhaust fan venting installation at the soffit, the underside of a roof’s overhang, is utilized less. Check with your local building code regarding a soffit installation because not all municipalities allow this venting option.
When installing a bathroom fan, you need to choose the best ductwork and vents for your venting needs. Lambro makes it easy to select a vent cover / hood vent cover for the vent termination outside of your home whether it is from an outside wall, a soffit or the roof.
Vent covers help keep debris and animals from entering the ductwork and clogging it. Be sure to choose a cover that fits snugly and is weatherproof.
Some common types of vents people consider to use for venting a bathroom exhaust fan:
– Wall vents
Wall vents are one of the most common through-the-wall ventilation options for a bathroom whether or not the bathroom has a window. Most of Lambro’s bathroom venting products work well for either a wall or ceiling bathroom fan installation by going through an exterior wall in order to exhaust moisture and smells to the outside.
– Roof vents
Roof vents are an effective option for a bathroom fan’s exhaust. Roof vents are generally considered easier to install and can be placed more conveniently and flexibly than a new gable ridge or soffit vent.
– Gable vents
Gable vents can technically be used to eliminate the humid air from a bathroom fan. If you’re set on using a gable vent as a discreet exhaust for your bathroom fan, it would be much better to install a new or additional gable vent if there is another available location.
These vents are discreet, and taking advantage of that would keep you from having to add new and possibly unsightly fixtures to your home. Be aware that using a pre-existing gable vent as your exhaust point could significantly restrict airflow, preventing the ventilation system from doing its job of keeping an attic moisture-free. Gable vents can also have a backdraft problem in windy conditions of sucking expelled moisture back into the attic. A damper optimizes the functioning of your ducting and can ease concerns about moisture being blown or sucked back into the attic / home.
– Soffit vents
Like Gable vents, Soffit vents run a risk of sucking expelled moisture back into the attic.
Houses with gable roofs often pair gable vents with soffit vents since they tend to work to regulate the attic’s temperature and humidity with the flow of air. If you block either of the existing soffit or gable vents you can completely throw off the passive ventilation system.
– Ridge vents
Venting moist bathroom air through a ridge vent is not recommended since the moisture can still hit the roof sheathing, and some will fall back into the attic which could lead to mold growth and wood damage.
Each method, venting a bathroom fan through the roof, through a side wall, or out an exterior eave or soffit has its own pros and cons, so it’s important to choose the method that’s right for your home. In each case ducts, vents, vent clamps and connectors will be required.
Pros: A roof vent exterior cover is less likely to become blocked than other types of vents – It is also less visible from the ground, so it can be a good option if you’re concerned about aesthetics.
Cons: A roof vent exterior cover can be more difficult to install than other types of vents. The roof vent needs to be sturdy to withstand the exterior elements. We recommend having a licensed roofer install the bathroom fan roof vent. – It may require more maintenance over time.
