Bathroom Exhaust Fan Roof Vent Leaking

The first step is to head to the attic.

Bathroom exhaust fan roof vent leaking.

Most bath vents for homes are 3. You step out of the shower and then there it goes. Venting through a roof vent or exhausting them in the attic could cause moisture problems and rot. Vent pipe leaks during heavy rain can occur if you have cracks in your vent pipe boot or flashing.

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. I see many questions about leaking bath exhaust vents. Pay close attention to check whether there is insulation around the duct. These boots vary in quality flexibility and longevity.

Check the damper at the fan. While this doesn t indicate that your roof is leaking it does potentially indicate that your exhaust fan isn t vented correctly. So you re taking a hot shower because you want this stormy night to be as relaxing as it can be. When it does then there s obviously something wrong.

The tubing or the ducting of the exhaust fan should be insulated and vented to the outside. Next make sure you have one of the new roof exhaust vents on the roof and properly sealed. Vent your bath and kitchen exhaust fans through the roof through a special roof hood. When your roof was installed each vent pipe received a flexible boot to seal water around the round surface of the vent pipe.

If bath fan ducting isn t properly insulated the moist air from your house will condense inside the duct. However you shouldn t expect for it to come out of your leaking bathroom exhaust fan or ceiling vent. Also known as plumbing jacks or roof jacks roof vents are the pipes that protrude out and let the gases in your kitchen and bathroom escape. If not this is the problem and you can solve it insulating around the duct.

Next make sure it is securely fastened on both ends of the pipe. I recommend replacing the vent pipe with insulated vent pipe.
