Roof Ventilation
Essential for roof health and energy efficiency
Proper ventilation extends roof life, reduces energy costs, and prevents moisture damage. From ridge vents to solar-powered attic fans, find the right solution.
Why Proper Ventilation Matters
Temperature Control
Reduces attic temps by 50°F+
Moisture Prevention
Stops mold and rot damage
Energy Savings
Cuts cooling costs 10-30%
Extended Roof Life
Prevents shingle damage
Ventilation Basics: Intake + Exhaust
Effective roof ventilation requires balanced airflow. Cool air enters through soffit/intake vents at the eaves, flows up through the attic, and exits through ridge/exhaust vents at the peak.

- • Soffit vents (continuous or individual)
- • Drip edge vents
- • Edge vents
Exhaust Vents (Top)
- • Ridge vents (most common)
- • Power/solar attic fans
