What does the presence of pooling on a roof suggest?

The presence of pooling on a roof indicates previous moisture issues. When water pools on a roof, it often signifies that the drainage system is not functioning effectively, which can lead to water intrusion and damage over time. This stagnant water can create an environment conducive to leaks and facilitate the growth of mold, mildew, and deterioration of roofing materials. Identifying pooling is crucial for assessing the health of a roof, as it suggests that there may have been ongoing or past issues related to moisture management that need attention to prevent further damage and deterioration. This makes it essential for roof inspectors to closely evaluate areas of pooling for signs of water infiltration and to recommend corrective measures accordingly.
