Clothes Dryer Flue

SC, United States   

We bought a 1 story house (5 years old) which has the dryer flue going straight up to the roof (like a chimney).  It doesn’t seem like a dryer could blow the lint straight up very well.

Should I put an elbow in the flue in the attic and send it out through the fascia of the house?

Clothes dryer vents have traditionally been a short as possible run and fairly horizontal.
I have seen vertical venting due to location in the home.
As long as the vent has a rain protection cap on it and is able to exhaust the heat, I see no need to move the vent or add an elbow.
The vent is NOT TO MOVE LINT, it is to exhaust the heat from the dryer. The lint should be caught int he trap in the machine itself/
Just please remember to clear the vent pipe / trap and inner piping occasionally to prevent a Dryer Vent Fire, just as you would a chimney for a heating appliance. Lint will escape the trap and get into the pipe.

We do tons of dryer vents and have found the vertical installation is now the most common one found. While you think it might be hard to exhaust lint that way, if it is kept clean it has no problem. Putting a bend in the vent causes it to slow the force down and gives a place for line to build up. Sure the vent is to exhaust the heat but with the heat comes lint. I would just suggest leaving it alone and maintaining it on a regular basis. Many people, installers included do not know or think a dryer vent ever has to be cleaned but they do at least need checking on an annual basis. If heavily used an even more frequent basis may be needed.
