Roof Venting For dryer efficiency and safety, the shortest and straightest ducting route is always best. Every turn increases friction loss (unless you use non-restrictive elbows). Air velocity reduction from friction loss promotes lint build up and makes the dryer work harder to completely dry each load.
Should you vent a dryer through the roof?
Dryer vents should always be vented through the side of the house and not vented through the roof, and ideally, the exit should be fairly close to the ground.

While using PVC for some venting applications is acceptable, you should not use PVC to vent a dryer. PVC has a maximum temperature rating of 140 degrees. Dryer exhaust output can range from 130 to 165 degrees. PVC can buildup a static charge that can ignite lint buildup and cause a fire.
What is code for dryer vent?
The maximum developed length of a clothes dryer exhaust duct shall not exceed 35 feet from the dryer location to the wall or roof termination. The maximum length of the duct shall be reduced 2.5 feet for each 45-degree (0.8 rad) bend, and 5 feet for each 90-degree (1.6 rad) bend.
Where is the best place to vent a dryer?
It’s best to route the dryer vent in a horizontal path to the home’s outside wall. All horizontal runs should pitch 1/4-inch per foot to the outside. This will help to avoid moisture from sitting in the pipe or draining back to the dryer.
