Bathroom Exhaust Fan Through Roof Or Soffit

This way we can make sure both are positioned properly.

Bathroom exhaust fan through roof or soffit.

You certainly can run the vent through a soffit. And while both a roof vent and an overhang vent perform this task there is one big difference. The 2nd bathroom vent drips on the floor and is ruining the ceiling. As the warm moist air leaves the bathroom through a soffit it leaves in a downward motion.

When a bathroom exhaust duct terminates in a soffit it drips. The 2 pipes one a 4 master and the other a 3 2nd do not go through the ceiling but into a common box that goes through the roof. If you do you re dumping your exhaust inside the soffit space not outside the building. Cooler air which is found under your roof overhang soffit is drawn up through the perforations of the soffit and exhausted through your roof venting system.

Remove the tape from the fan first. The master bathroom and the 2nd bathroom vent through the roof and through the same opening. The bathroom exhaust should never be vented anywhere near nor through the soffit area. So then the argument is that your humid bathroom exhaust comes out and is sucked back into the attic by the soffit vents built into most roof attic systems.

A hole in the roof may cause it to leak. Here is a guide on how to vent a bathroom fan through soffit. A down through soffit exhaust vent design by leaving warm air in the exhaust duct when the fan is off creates a heat trap that reduces heat loss out of the bathroom through the exhaust fan duct when the fan is off in comparison with up routed vents or even horizontal vents through a gable end wall. Check the damper and the screen in prior to installation.

In other cases it can be difficult to vent a second story bathroom to the side of the house. Opposed to the traditional practices of venting a bathroom fan through a side wall or roof you can also vent it through a soffit which is much preferable in some cases as we will see in this article. In cold weather it forms icicles. That s why wall terminations are preferable to soffit terminations.

Idea 5 connecting the duct to the bathroom fan. I am getting a new roof installed and tear off and likely a lot of plywood and am simultaneously getting a new bath vent fan. If you are also amongst the people who are interested in avoiding making a hole in the roof and get the deed done using a soffit you have come to the right place. Then the vent terminates outside.

The roof contractor recommends the soffit to minimize protrusions through the roof. The point of a bathroom exhaust vent or any vent really is to remove hot moist air from the house. Next we must slip a worm drive metal clamp on the inside part of duct liner. I have gotten mixed opinions on whether to vent the new fan through the roof or through the soffit eave.
