roof vent

[jsmith6752]

I am adding a laundry and bath. I am trying to find out if I need an additional roof vent. It will discharge at the very end of the line. It is a two story house and the new bath will be on the first floor...thanks

the new fixtures will have to be vented through the roof. If you cannot tie into an existing roof penetration then you will have to add one. Unless of course your local juristiction allows a studor type vent.
