Duraflo® gooseneck roof exhaust vents provide high-performance ventilation, extracting moisture and heat from attics, bathrooms, kitchens, and laundry rooms. The patented design adds five inches of height for effective snow clearance. Internal dampers minimize backdraft, and the design diverts precipitation, while a molded screen wards off birds, insects, and pests. These durable, weather-resistant vents are available in various colors and accommodate ducts ranging from 4 to 8 inches.
