I have two bathrooms and both are vented to the soffit with flex tube like on a dryer. One is not working and putting moisture in attic. I disconnected the one I was having trouble with and taped off the vent to see if it was the problem and it was. Now I'm wondering if I can flex tube it up to the ridge vent, I do not have roof vents. Seems like that should work. What do you think?
