What condition can lead to roof leaks if ventilation is inadequate?

When ventilation in a roofing system is inadequate, it can lead to moisture buildup, which is a critical factor in the development of roof leaks. Proper ventilation allows air to circulate in the attic or roof space, helping to manage humidity levels and temperature. When moisture trapped in these spaces cannot escape, it can condense on surfaces, leading to dampness and potentially creating a breeding ground for mold and mildew.

This accumulation of moisture can harm insulation and wood structures, leading to deterioration and creating a pathway for water to penetrate the roofing system over time. If this process goes unchecked, the moisture buildup can eventually compromise the integrity of the roofing materials, leading to leaks that can cause significant damage to the structure beneath. Proper ventilation mitigates these risks by promoting airflow, which helps to keep roof spaces dry and safe from moisture-related issues.
