What are eave vents?
Eave vents are openings into the attic space that control temperature and moisture. They are typically located on the upper edge of the perimeter walls of a house, where the walls meet up with the overhang of the roof. These vents, which commonly are 2″ – 3″ diameter holes bored through the eave board, or are rectanguar in shape, allow air to pass through them, into the attic space, in order to provide ventilation. Most building codes specify eave vents for attics to prevent a buildup of moisture and temperature, which can lead to mold growth and decay. Eave vents offer embers, flames and smoke an easy entry point.
