What can excessive leaves on a roof lead to?

Excessive leaves on a roof can lead to blocked drainage and moisture retention, which is a significant concern for roofing health. When leaves accumulate, they can create barriers that prevent proper water flow to gutters and downspouts. This obstruction can cause water to pool on the roof, leading to various issues such as water damage, mold growth, and deterioration of roofing materials. Moreover, stagnant water can increase the risk of leaks and structural problems, undermining the integrity of the roof over time. Therefore, maintaining a clear roof surface is essential to ensure proper drainage and to minimize the risk of moisture-related damage.
