Undereave vents are a type of attic intake vent that make up half of a balanced attic ventilation system for each roof. Exhaust vents make up the other half of the system. Together they help remove any built-up heat and moisture inside the attic for year-round ventilation. Use the Lowe’s calculator to determine how many individual Undereave vents are needed per roof.
