    Roof Jack for Exhaust Fan Vent Termination

    Greetings,

    I was wondering if I can use roof jack to terminate a bath room exhaust fan vent. The roof jack comes with an insect screen.

    Thanks,

    Yes, provided that the jack is not used for anything else.

    I have read the exhaust fan termination shall prevent the outside air flow. Does this apply to my case?

    Ideally it means that it would prevent wind from blowing back into the fan connection piping, like with louvers or some other type of damper. As exhaust fans have a built in damper it kind of negates that whole argument. Air wont move into the pipe, because it has no where to go.

    I'd worry more about rain getting in.
