Vent clothes dryer through roof?

Quickstep | Posted in General Discussion on December 31, 2003 06:38am

I’m adding a stacking washer dryer in a new laundry room. It’s in a one story addition and since the dryer is on top, the most direct path is through the roof, but I wonder about sending all that moist air onto the roof, especially in winter. I thought about just shooting a pipe straight up (like a DWV vent) but have some concern about rain getting in, though I’d imagine I’ll have some condensation to deal with either way. Also, is the exhaust from an electric dryer cool enough to use PVC pipe?

    you can vent through the roof but use the proper hood so as not to let water in....no problem at all.........been there and done that.

    Why not use metal pipe? I see no reason why you couldn't use pvc but I'd transition it from metal out of the dryer into pvc just to give it a second to cool out......Thats just a feeling, not a scientific explanation.

    Be dry

    Be careful with the plastic......doesn't it react similiar to plastic vacuum lines in a shop ie static electricity?

        pvc will collect lint quite well for you.  boss had me go figure out why his dryer wasnt venting right,  ina 15' run of 4" pvc i could not see light from end to end plugged solid and his house is less than 2 years old.   justa thought.An inch to short.  That's the story of my life !

    There was a discussion of the same situation about a month ago. Writer was worrying about the snow.

    Consensus was insulated metal pipe (in cold climate) plus the proper roof vent hood.

    You can't go straight up like a plumbing vent. Rain goes into the DWV and drains to the treatment plant, in your case rain drains into your dryer. Not a pretty picture.

    Hi Chuck

    Don't know what part of the country you are in but warm air going through a dryer vent hitting colder air on top creates condensation on the outside of the pipe. This slides back on the outside of the pipe eventually hitting the drywall ceiling. I insulated my bathroom fan duct with R-30 bats through the attic to keep the air warm to the exhaust point on the roof. BC is like Seattle climate. After three years no problem so far.

    Happy NY
