FM 1-29 is primarily concerned with which roofing category?

• A. Single-Ply Roofing Systems covering EPDM, TPO, PVC systems, membranes, and seam performance
• B. Built-Up Roofing with hot asphalt
• C. Metal roofing assemblies
• D. Spray polyurethane foam systems

Answer: (A)

FM 1-29 focuses on single-ply roofing systems, specifically EPDM, TPO, and PVC membranes, and how their field seams and joints perform. This data sheet is about the performance characteristics of these thin membrane systems used on low-slope roofs, with emphasis on membrane materials, seam types, attachment methods, and how seams behave under service conditions and wind loads. That scope makes the option describing single-ply membranes and seam performance the best match, since it directly addresses the materials and seam concerns that FM 1-29 covers. Other roof types—built-up roofing with hot asphalt, metal roofing assemblies, and spray polyurethane foam systems—are governed by different data sheets and design considerations. They have distinct materials, installation methods, and failure modes that FM 1-29 does not primarily address.
