Steep slope structural roofs are primarily designed to be installed over open framing. This type of decking provides a solid framework that effectively supports the roofing materials and allows for appropriate drainage and ventilation, which are crucial for the longevity and performance of steep slope systems. The open framing allows for proper spacing and support under the roofing, accommodating the weight and distribution needs of the materials used.

While plywood, fiberboard, and concrete slab can also serve as decking materials, they are often used in other roofing applications or specific situations that do not pertain to the installation of steep slope roofs. For instance, plywood is typically used in a variety of roofing systems but does not specifically enhance the performance characteristics essential to steep slope roofs compared to open framing. Understanding the appropriate use of different decking materials is fundamental for achieving the best results in roofing applications.
