Can you run dryer vent vertically?

DEAR BOB: A vertical dryer vent is typically a problem because it acts as a moisture condenser. The sheet metal duct is cooled by the outside air in the attic. When a laundry is situated near the center of a home, especially if there is a slab foundation, a vertical duct is often the only option for ventilation.

How can I keep condensation out of my dryer?

This slope allows condensation to drain back toward the dryer, and you can control it by periodically unhooking the vent from the dryer and allowing the water to drain.

How do you attach a roof vent to a wall?

You are then back to sticking the vent to the wall with the brackets and screws. Attach the roof vent to the duct that is from the top of the roof. Use the screws to place the vent cap securely onto the roof. To secure it, you can then use the caulk to go around the edges of the vent cap.
