Question: 1 / 400

How does improper drainage affect a roofing system?

It increases the life expectancy of roofing materials

It can cause water pooling that leads to leaks and mold growth

Improper drainage significantly compromises the integrity of a roofing system. When a roof is not equipped with an effective drainage system, it can lead to water pooling. This stagnant water can infiltrate the roofing materials, creating leaks that not only damage the roof itself but also pose a risk to the underlying structures. Moreover, prolonged moisture can foster an environment for mold growth, which is detrimental to both the roof and the health of the building's occupants. Therefore, acknowledging the importance of proper drainage is essential for maintaining a functional and durable roofing system.

While other options address aspects of roofing systems, they do not accurately reflect the consequences of improper drainage. Therefore, the focus remains on how insufficient drainage management can lead to significant issues like water pooling, leaks, and subsequent mold growth.
