Many homeowners in Edmonton, St. Albert, and Sherwood Park don’t realize their dryer vent may exit through the roof. While rooftop dryer vents are common, they can create problems when the wrong vent cover or screen is installed. During dryer vent cleanings, we regularly find rooftop dryer vents that are partially or completely blocked with lint buildup. One common issue we see is a screen covering the dryer vent opening. These screens can collect lint over time, restricting airflow and making the dryer work harder. A dryer vent is designed to move hot, moist air and lint safely outside the home. When airflow becomes restricted, homeowners may notice longer drying times, a dryer that runs hotter, or excess lint buildup around the vent area. Another issue we often see is after roof replacements. Some roofing installations may include a vent style that was not designed specifically for dryer exhaust. Certain roof caps can trap lint instead of allowing the dryer to properly release air outside. A properly functioning dryer vent termination should allow airflow while helping prevent unwanted outdoor elements from entering. Regular dryer vent cleaning helps remove lint buildup and keeps the system operating more efficiently.
