Bathroom Exhaust Fan Leaking Water When It Rains

So the first place that i would check for any bathroom ceiling leak would be the flashing around the vent pipe.

Bathroom exhaust fan leaking water when it rains. I have checked the bathroom fan seal as well and it is not condensation because it is only during heavy rains. After all this is where you take a bath. You can expect your bathroom to get wet. The tubing or the ducting of the exhaust fan should be insulated and vented to the outside.

It is on the first floor. How do i fix this. My bathroom fan leaks water during very heavy rains. The exhaust is also on the first floor on the side of the building not the roof.

My bathroom exhaust vent leaks when there is a heavy rain. When it rains water is getting through the cover and the water is traveling down the vent hose and then it is exiting from your bathroom fan onto the floor. And very often when you have a leak in the bathroom ceiling what s happening is the water is getting in around the pipe that goes right through the roof in that particular area. If your roof vent leaks during heavy rain the rain may be blowing up under the hood and into the vent.

Pay close attention to check whether there is insulation around the duct. We have inspected the attic and there is no rotting wood and we cannot figure out how to stop the problem. The fan is on the ceiling and t. It should open only under pressure from the warm air to let it out and remain closed the rest of the time.

The pipe connect to the bathroom s vent fan and that s it. Check the damper at the fan. I have a bathroom fan that leaks during heavy rains. How do i fix.

And on occasion a hard driving rain with whipping wind will cause roof vents to leak water. It this is the case you need to create a breathable shield to slow the driving rain drops while still allowing air flow. When it does then there s obviously something wrong. When the exhaust fan is on the damper should on and vice versa.

Besides the roof it is also possible though unlikely that your bathroom fan vent goes to the exterior vertical wall and it may have just enough slope that water is still dripping through vent hose and into your bathroom. It seems like it may be coming in through the vent when the rain wind blows sideways during a heavy rain fall. When there is heavy rain i get water drips into my bathroom after getting in the attic i can see water slowly dripping from around the vent to on top of the vent in the bathroom not in the pipe itself. However you shouldn t expect for it to come out of your leaking bathroom exhaust fan or ceiling vent.

If not this is the problem and you can solve it insulating around the duct.
