All of my bathroom fans are vented into the attic not to the outside. A new roof goes on tomorrow so I am having roof vents installed. But I have only found two vent hoses in attic. I have three bathrooms each with fan.
Is it common and acceptable to put in a "T" or "Y" and vent two bathroom fans with one hose?
Do I have two or three roof vents installed?
