I have recently completed a second-story deck on the back of our house. I plan to turn the space underneath it into a screened-in porch. This will include a ceiling of some sort hanging from the deck joists.

Our dryer currently vents just under the deck. I need to somehow extend the vent to the edge of the deck (about 10 feet). THis will be done inside the joist cavities under the deck. I live in the midwest, so I have both rain and freeezing temperatures to deal with.

My question: What sort of vent pipe should I use?
- 4" solid aluminum
- 4" galvanized
- 4" flexible aluminum

I want something that will stand up to the elements as much as possible.

Thanks!
