  • Properly designed ventilation is a key component of a heathy roof environment and exterior building envelope. A balanced intake and exhaust system will ensure the attic space is not retaining excess moisture that could result in damage to the roof decking material, excess mold and mildew growth, ice dams causing shingle damage, algae growth, and water or mold stains on the interior ceiling and walls. Additionally, proper ventilation in the exterior building envelope can help prevent premature deterioration of the siding and roof covering materials. This course explains the fundamentals of attic and envelope ventilation and highlights the importance of a balanced system, identifies the many venting options available, and discusses various ventilation case studies.
