Dryer vent question
We have a gas dryer stacked on washer in garage. The vent goes right behind dryer to the side of garage, a little away from a small front porch. And it was behind bushes.
We are adding a new room in front of the house. Between the garage and new room will be a 7' wide 15' long covered 'porch'. The existing vent will be located right next to the main entry door in this 'porch'. I am thinking about moving the vent to another location. And here are my options:
1. put the vent through the roof of garage. But I was told by my contractor, that the lint will be all over the roof.
2. run the pipe up to garage ceiling, then run 20+ feet across to the other wall. The total length could be 25-30 feet. If I go this option, do I need to have a inline booster fan installed in the middle of the pipe? Does the boost fan need to clean once a while?
Which one will be better? Or, will there be better option for me?
