What type of roof systems are ideal for steep slope assemblies?

• A. Single ply membrane
• B. Slate, clay tile, asphalt shingle
• C. Rubberized roofing
• D. Built-up roofing

Answer: (B)

Steep slope roof systems are best suited to materials that effectively shed water and can withstand the potential forces acting on them, such as wind uplift. The choice of slate, clay tile, and asphalt shingles fits this application well because these materials are lightweight, durable, and have interlocking designs that assist with water drainage. Their design is conducive to vertical installations, which enhances their performance on sloped surfaces. In contrast, single ply membranes are typically used for low-slope or flat roof systems. Their performance relies on continuous sealing and more even surfaces rather than the pitched surfaces provided by steep slope roofs. Similarly, rubberized roofing is generally designed for low-slope applications where flexibility and waterproofing are key, making it less suitable for steep slopes. Built-up roofing is also primarily utilized on flat roofs, characterized by a series of layers to form a waterproof barrier, which does not align with the needs of steep slopes. Therefore, the combination of slate, clay tile, and asphalt shingles directly addresses the requirements for effective water shedding and structural integrity appropriate for steep slope installations.
