Ventilation Matters!

• Reduces excessive attic heat that can prematurely age shingles. 
• Helps prevent curling, cracking, and shortened roof life.

• Allows hot air to escape during the summer. 
• Can reduce attic temperatures by tens of degrees under the right conditions.

• Removes moisture-laden air from the attic. 
• Helps prevent mold, mildew, wood rot, and rusted fasteners.

 Reduces moisture buildup that can warp or delaminate roof sheathing. 

• Reduces heat buildup in the attic, easing the load on air conditioning systems. 
• May help lower cooling costs.

• Many roofing manufacturers require proper ventilation as part of their installation guidelines. 
• Improper ventilation may affect warranty coverage.
