When should I consider using a Gooseneck Roof Vent? Household appliances that are exhausted through the attic need to be connected to the proper roof vent. Bathroom fans, clothes dryers and kitchen hood exhaust fans are all vented using a type of Gooseneck Roof Vent. Goosenecks are installed much like an exhaust vent but do hold one key difference as they have an interior connection that allows exhaust pipes to be fastened directly to the vent. This allows for continuous air flow and eliminates any heat or moisture from escaping into the unconditioned attic space.
