Q 21. How do you ensure proper ventilation in a roofing system?
Proper ventilation is essential for the longevity of a roof. It prevents moisture buildup, which is a major contributor to rot, mold, and premature roofing material failure. A well-ventilated roof allows for the efficient escape of warm, moist air from the attic space. This prevents condensation and keeps the attic temperature cooler in the summer.
Achieving proper ventilation typically involves a combination of intake vents (located in the soffits) and exhaust vents (located in the ridge or gable). The balance between intake and exhaust is critical. Insufficient intake vents can restrict airflow, while insufficient exhaust vents can create negative pressure, leading to backdrafting and moisture problems.
During inspections, I assess the existing ventilation system, calculating the required ventilation based on the attic’s size and the type of roofing material. I would recommend upgrades if needed, ensuring proper airflow. The overall goal is to create a balanced, efficient system that prevents moisture problems and prolongs the life of the roof.
