BREATHERS

Breathers are essential for maintaining proper ventilation and moisture control in roofing systems. They allow trapped air and moisture to escape, reducing condensation and pressure buildup, while preventing water and debris from entering. By promoting airflow, breathers help protect the roof from moisture-related damage and ensure a balanced air pressure.
