Roof-mount power fans are a type of motor-driven 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. Use the Lowe's calculator to determine how many roof-mount power fans are needed per roof.
