How to best vent 2nd story internal laundry room

melissat99April 22, 2013

We just bought a house with an internal 2nd story laundry room where the dryer currently vents directly into the attic. We obviously need to extend this outside, but am wondering how best to do so. Should we do the vent straight up through the attic roof, or turn and go out the gable ends of the house?

Attic isn't particularly tall, so I'm guessing extending the vent straight up would be ~ 8 feet. Extending the vent out the side of the house would be ~14/15 feet.

And we are not trying to do this ourselves - I just need to figure out if it will be going up through the roof in order to coordinate that with the other items (water heater / HVAC replacements) that will be creating new roof holes so that I can try to get those all done at once so that I only need to pay for one visit from the roofers.

Thanks for any help!

The best practice would be to go straight up and out the roof.

The less bends there are in the run the less resistance and possibility of lint build up there is.

If you live in a cold climate, be sure to insulate the ducting.

Plan ahead and make it easy to detach/reattach the ducting so you can easily clean/inspect for lint.

Get the best roof vent now to prevent problems later. (check out link)

georgect - thank you for the reply! If we're venting out the attic, do you know who the best professional is to handle that kind of work? (Hoping to get all my new roof holes put in place on the same day.)

And we're in Houston, so I'm guessing insulation won't be as big of a concern for us.

An experienced contractor or carpenter.

No you shouldn't need insulation for your area.

Straight duct pipe listed for a dryer is fine (no PVC, no semi-flexable aluminum etc).

I wouldn't recommend going more than 15 feet high in total height. Most manufacturers mention this in their manuals.

I live in Houston and we have this kind of dryer vent. The laundry room is in the middle of the house and the vent just goes up and out the roof in a straight shot. There is a 90 degree elbow where the bottom comes out of the wall. It works well. Even a chimney sweep company could install this for you.
That's who we call to have ours cleaned out every few years.
