Ventilation is often an overlooked aspect when it comes to roofing in San Diego. However, it plays a pivotal role in the longevity and efficiency of your roof. At San Diego County Roofing & Solar, we believe that understanding the nuances of proper roof ventilation can save you from future headaches, such as mold formation and increased energy costs.
What is Proper Ventilation?
Proper ventilation is quantified in terms of Net Free Inches (NFI). Contrary to popular belief, the primary objective of ventilation is not cooling but drying. Adequate air movement minimizes the risk of mold and mildew, which thrive in damp conditions.
The Dual Components of Ventilation
Exhaust is the first component of a well-ventilated roof. It is facilitated by the natural rise of warm air. Various outlets like turbine, gable, dormer, and ridge vents allow this warm air to escape, thereby creating exhaust.
The second component is intake ventilation, which is usually situated at the lower end of the roof slope. This can be achieved through drilled “bird holes” above the bearing wall or through low-profile roof vents. Intake is crucial for optimum ventilation and should ideally match the net free inches of exhaust.
Why is Intake More Important than Exhaust?
If achieving a balance between intake and exhaust is not feasible for some reason, then intake takes precedence. This is because intake ventilation sets the stage for effective exhaust, ensuring that fresh air circulates properly throughout the roof structure.
The Role of Ventilation in Cooling
While drying is the primary aim, cooling is an inevitable secondary benefit of proper ventilation. When hot air is trapped in the attic, it can permeate the ceiling and elevate indoor temperatures. Effective ventilation prevents this by allowing hot air to escape.
