What can be a consequence of inadequate attic ventilation?

Inadequate attic ventilation can lead to excess moisture accumulation, which creates an environment conducive to mold growth, particularly on insulation materials. When humidity levels rise in the attic due to insufficient airflow, it can result in condensation forming on surfaces, including insulation. This moisture can promote mold spores to develop and thrive, compromising both the structural integrity of the insulation and the overall air quality within the home. This issue is significant because mold not only damages materials but can also pose health risks to the occupants, making proper ventilation critical in preventing such consequences.
