SOUTH SAN FRANCISCO — Ventilation is a critical roof component that affects both the longevity of roofing materials and the health of the home’s inhabitants. When a roof isn’t adequately ventilated, hot air can become trapped in the attic and produce condensation, which can lead to the formation of mold and mildew. Not only does this prematurely deteriorate the roofing materials, it can contribute to unhealthy conditions in the home and exacerbate asthma and allergy symptoms.
A quality roofing contractor will follow a clear-cut formula to ensure proper roof ventilation. This involves an appropriate balance of cool air intake and exhaust to ensure adequate air circulation. The goal is to prevent excessive temperature highs and other conditions that produce condensation and mold.
Considering its importance, if your roofing contractor isn’t talking about ventilation, it should raise a red flag. Ask them to provide a detailed explanation of how they plan to ensure proper ventilation with your roof.
