American Aldes High-Performance Roof Caps are engineered to minimize noise and pressure resistance for maximum airflow, all while effectively removing moisture and condensation from the duct system. High-Performance Roof Caps are designed for durability and aesthetic value, and they can be installed on any roof pitch or shingling.
These low-profile, low-pressure roof caps include integral backdraft/weather dampers, removable bird screens, leak-proof roof flashing, and extended duct collars for simple installation. Roof caps are available in heavy-gauge galvanized steel, stainless steel, copper, or aluminum in sizes 4″, 5″, 6″, 8″, 10″ and 12″. Dryer Roof Caps are also available.
