Together with intake vents, exhaust vents provide an indispensable air ventilation system for any residential or commercial property. While intake vents allow cool air to enter a space, exhaust vents allow warm air (exhaust) to escape. Exhaust vents not only allow interior spaces to be climate-controlled more efficiently and evenly — they also improve the longevity of a building’s roof by preventing ice damming. Exhaust vents also remove excess moisture and pollutants from interior spaces, protecting properties and those within them.
