True or False: Many roll roofs have insufficient pitch to properly shed water.

Roll roofing is often used in low-slope applications, which means it typically has a very minimal pitch. A low-slope roof is one that has a rise of less than 3 inches for every 12 inches of horizontal run. This design can sometimes lead to challenges in water drainage, especially during heavy rainstorms or in certain climates where moisture levels are high.

The key reason why many roll roofs may struggle to shed water effectively is due to their insufficient pitch. When a roof does not have an adequate slope, water can pool rather than flow off, which can lead to leaks, water damage, and a reduction in the lifespan of the roofing material. Therefore, the statement that many roll roofs have insufficient pitch to properly shed water is indeed true, as it emphasizes the importance of proper design and installation to ensure efficient water drainage on these types of roofs.
