I have a bathroom fan that leaks during heavy rains.
It could be as simple as pulling some debris out of the vent or caulking or more complicated.
Pay close attention to check whether there is insulation around the duct.
And on occasion a hard driving rain with whipping wind will cause roof vents to leak water.
Here are a few things that you need to check if your fan is leaking during or after the rain.
We have inspected the attic and there is no rotting wood and we cannot figure out how to stop the problem.
I have checked the bathroom fan seal as well and it is not condensation because it is only during heavy rains.
The usual cause is condensation inside the duct.
Check the damper at the fan.
Many people notice the issue when the bathroom exhaust fan starts dripping on their head as they step out after a shower.
However you shouldn t expect for it to come out of your leaking bathroom exhaust fan or ceiling vent.
My bathroom fan leaks water during very heavy rains.
It seems like it may be coming in through the vent when the rain wind blows sideways during a heavy rain fall.
In case the vent.
If not this is the problem and you can solve it insulating around the duct.
After all this is where you take a bath.
If your leaking bathroom exhaust fan has been going on for some time it may be a very good idea to remove the actual bathroom exhaust fan and check for damage in the ceiling cavity.
The exhaust is also on the first floor on the side of the building not the roof.
The tubing or the ducting of the exhaust fan should be insulated and vented to the outside.
It this is the case you need to create a breathable shield to slow the driving rain drops while still allowing air flow.
If your roof vent leaks during heavy rain the rain may be blowing up under the hood and into the vent.
During the last storm it even started leaking through the ceiling light which is about 4 feet away from the exhaust fan on the ceiling.
The most common reason a bathroom exhaust fan leaks when it rains is because the bath vent hose is in a vertical slope and exhausts on top of the roof.
In many cases if the exhaust is resting on the top of the roof the fans might show leakage signs.
When it does then there s obviously something wrong.
This is no fancy over the stove exhaust system just a round circular fan that sits flush up against the ceiling and vents to the roof.
One most common reason that leads to the leaked fans in the bathroom is the vertical slope of the bath vent hose.
You can expect your bathroom to get wet.
In winter when the warm moist air from the bathroom hits cool air in the attic or outdoors it condenses sending drips back down the ductwork.
There may be damaged insulation damaged drywall damaged wood framing and there may be mold growing.
It is on the first floor.
