When was the last time you checked your attic ventilation? This often overlooked component has a major impact on indoor comfort and health by regulating moisture, temperatures, and airflow throughout the home. As professional roofing experts, the team at C&M Roofing and Construction understands effective ventilation is key for preventing issues down the line.

Here, we’ll explore best practices for attic ventilation and maintenance tips that can significantly improve indoor air quality. By following our recommendations, homeowners gain greater control over their home’s environment and protect their roofing investment long-term too.

Types of Vents 

Proper cross-ventilation requires intake vents, typically soffit vents located along the eaves, and exhaust outlets like ridge vents or gable end vents. Intake and exhaust must be evenly balanced according to space and climate needs.

Location is Key

Intake vents providing fresh air should be distributed evenly along the entire soffit. Exhaust vents located high along ridges or gable peaks encourage airflow through the attic cavity. Placing vents strategically optimizes circulation.

Sizing Matters

Attic ventilation requirements factor square footage and insulation levels following local codes and manufacturer recommendations. Under-ventilated attics retain damaging heat and moisture while over-ventilated spaces waste energy dollars unnecessarily.  

Keeping Vents Clear

Screened vents risk clogging over time from nests, leaves, and dust-blocking airflow. Clean intakes biannually, check exhaust fans yearly and trim back interfering tree branches. Unobstructed vents perform at full capacity.

Sealing is Paramount  

Air-sealing attic bypasses and leaky top plates using caulk creates a tighter barrier. This ventilation targets intake/exhaust specifically versus wasteful uncontrolled air exchange within walls. Our attic sealing services yield big comfort and efficiency wins!
