Attic Ventilation: Cool Home, Lower Energy Costs

Proper attic ventilation can reduce cooling costs by up to 10-20%, with strategic airflow management preventing heat buildup and minimizing energy waste through intelligent temperature regulation and comprehensive roof system protection.

​

Attic 
Ventilation

Attic ventilation works by drawing in cool, fresh air through intake vents (like soffit vents) and allowing warm, humid air to escape through exhaust vents (like ridge vents), creating a continuous airflow that helps regulate attic temperature and moisture levels.​
