Soffit exhaust vents facilitate the flow of air through an attic to minimize the amount of moisture that builds up during humid days. A build up of moisture in an attic can cause damage to a home due to condensation.
A soffit exhaust vent is typically paired up with an intake vent that is installed in the eaves of an attic. The intake vent functions to draw in cooler air from the outside of the house while simultaneously releasing warmer air from its exhaust vents. A soffit vent system is generally installed with other vent systems that help remove moisture and air from an attic space.
