Is it OK to vent a dryer into the attic?
The International Residential Code allows you to run a dryer vent through the attic, but you can’t terminate it there. Doing so would fill your attic with warm, moist air that could rot the framing and ruin the attic insulation, and lint from the dryer could create other problems.
Can dryers be vented to roof?
When dryers are on interior walls with no direct route to the exterior, they can vent through the roof. Dryers venting through the roof need rigid metal ducting that extends straight to the roof exterior. Venting through the roof requires routine professional cleanings or risk lint build-up becoming a fire hazard.
Can a dryer be vented out the soffit?
Dryers can be vented through the soffit if it is not prohibited by the manufacturer. All other dryer installation regulations provided in the IRC must also be met. Notably, the dryer vent must not be within 3 ft of an opening into the building, including passive soffit vents. Never vent into the soffit.
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.
Why do they put dryer vents on the roof?
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.

How can I vent my dryer without outside access?
Can a dryer vent go straight out?
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. The maximum length of the exhaust duct does not include the transition duct. This means that vents should also be as straight as possible and cannot be longer than 35 feet.
