According to NRCA, what defines low-slope roof systems?

The definition of low-slope roof systems according to the National Roofing Contractors Association (NRCA) stipulates that these roofs have slopes less than or equal to 3 degrees. This classification is crucial in roofing as it impacts design, material selection, and drainage strategies. Low-slope roofs are particularly common in commercial and industrial buildings, where effective water drainage is managed through specific roofing materials and systems that accommodate the limited slope.

When slopes are defined as being below this threshold, it provides a clear standard for builders and contractors, ensuring that they can adhere to appropriate building codes and industry practices for installation and maintenance.
