Ventilation Matters!

 • Helps reduce excessive attic heat that can prematurely age roofing materials.
• Helps reduce heat and moisture conditions that may contribute to premature roof deterioration. 

 • Allows hot, humid air to escape from the attic through properly placed exhaust vents.
• When balanced with adequate intake ventilation, helps reduce excessive attic heat and improve airflow. 

 • Helps remove excess moisture from the attic that can contribute to mold, mildew, and wood deterioration.
• Proper ventilation helps protect roof decking, insulation, and other attic components from moisture buildup. 

 • Effective attic ventilation requires a balance between intake vents and exhaust vents.
• Intake ventilation is typically located near the eaves or soffits, while exhaust ventilation is installed higher on the roof to allow warm, moist air to escape. 

 • Proper attic ventilation can help reduce excessive heat buildup that increases the cooling load on your home.
• When combined with proper insulation and air sealing, ventilation can contribute to a more efficient attic and roofing system. 

 • Many roofing manufacturers include attic ventilation requirements or recommendations in their installation specifications.
• Improper or inadequate ventilation may affect certain roofing warranty provisions, depending on the manufacturer and product.
