For a modified bitumen roof, what is the minimum slope required?

The minimum slope required for a modified bitumen roof is 1/4:12. This slope helps ensure proper drainage of water, which is essential for the longevity and performance of the roofing system. A slope of 1/4:12 is generally considered the minimum to effectively manage water runoff and minimize the risk of standing water on the roof.

Standing water can lead to various issues, such as increased thermal expansion and contraction, moisture infiltration, and deterioration of the roofing materials. By maintaining a minimum slope, the design promotes efficient drainage, thus enhancing the overall durability and lifespan of the roof. This standard is particularly important in the construction industry, where adhering to code requirements and best practices is crucial for ensuring safe and reliable structures.
