Ridge vents are a type of attic exhaust vent that make up half of a balanced attic ventilation system for each roof. Intake 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. Ridge vents install at the peak to provide continuous exhaust airflow horizontally along the roof. Their low profile makes them nearly invisible from the ground. Use the Lowe's calculator to determine how many linear feet of ridge vent is needed per roof.
