Shipping Details

Roof louvers 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. Use the Lowe's calculator to determine how many individual roof louvers are needed per roof.

Horrible service

ordered materials hoping this would be the time they got it right after at least five prior delivery attempts resulting in a absolute 110% failure.
