Bathroom Exhaust Fan Leaking Water When It Rains

It should open only under pressure from the warm air to let it out and remain closed the rest of the time.

Bathroom exhaust fan leaking water when it rains. Vent cap with a proper stand off from the roof. My bathroom exhaust vent leaks when there is a heavy rain. If that s the source of the water adding an elbow to make the vent horizontal should fix it. And on occasion a hard driving rain with whipping wind will cause roof vents to leak water.

However you shouldn t expect for it to come out of your leaking bathroom exhaust fan or ceiling vent. How do i fix this. In this next picture we can see the care the installer took to get the same type of cap raised high enough above the roof surface to prevent leaking. It this is the case you need to create a breathable shield to slow the driving rain drops while still allowing air flow.

I have checked the bathroom fan seal as well and it is not condensation because it is only during heavy rains. It is not likely that water will ever get high enough to flood this vent.

After all this is where you take a bath. We had some water leaking onto the kitchen stove from the exhaust fan above it during the last couple of heavy rains. Nculbertyh sc does the water show up after a rain. 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.

You can expect water to come out of the shower or the faucet. We have inspected the attic and there is no rotting wood and we cannot figure out how to stop the problem. When it does then there s obviously something wrong. How do i fix.

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. It seems like it may be coming in through the vent when the rain wind blows sideways during a heavy rain fall. You can expect your bathroom to get wet. If your bathroom vent fan has water leaking around or next to it the problem may not be your roof but could be the ventilation system itself.

Whether wind driven rain will be a problem remains to be seen. I have a bathroom fan that leaks during heavy rains. If your roof vent leaks during heavy rain the rain may be blowing up under the hood and into the vent. If water drips from the bathroom exhaust fan the damper that normally controls the flow of air through the pipe may not be working correctly.
