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.

Worthless vents

Would Not Recommend

These are the worse vents to ever put on your house. The plastic reacts to the heat and cold. They expand and contract causing it to leak. No matter what sealant you use, it WILL leak. Having to replace with the aluminum vents now
