Dryer Vents on the Roof: What You Need to Know
The Problems with Dryer Vents on the Roof
Dryer vents on the roof cause way more problems than those that exit the side of the home. Improper vent covers are used in almost every case and they are difficult to clean. Adding to the problems is the fact that you cant easily see the cover to tell how well the dryer exhaust is flowing.
Improper roof vent covers used for dryer vents
While there are quality products designed specifically for use on roof dryer vents, home builders do not use them. They use cheaper roof vent covers designed for clean systems like bathroom exhaust fans. A dryer vent system is a dirty system because it is moving lots of water vapor and lint. These conditions can cause improper vent covers to clog which then leads to dryer repairs, dryer fires, roof damage and other issues. The two most common types of covers in Maryland are those with louver screens and those with flaps.
