Which roofing issue can contribute to water pooling?

Flat roofing designs are particularly prone to water pooling because of their minimal slope. Unlike pitched roofs, which are designed to direct water runoff efficiently towards gutters, flat roofs can have sections that do not drain as effectively. If a flat roof is not constructed or maintained properly, low spots can develop where water collects instead of draining away. This pooling can lead to various problems, including leaks, water damage, and deterioration of roofing materials over time.

While other options may relate to roofing issues, they don’t specifically create conditions conducive to water pooling in the same way that flat roofs do. For example, asphalt shingles are commonly used for sloped roofs and can shed water effectively. Pitched roofs actively encourage water runoff due to their design, and missing drip edges may cause water to flow incorrectly off the roof, but they do not inherently lead to the pooling problem associated with flat roofs.
