Recently, the roofing industry has been challenged by boiler plate specifications and a misunderstanding of design criteria. This results in roofing system installations that may not be suitable for the specific building, environment, or project conditions/location.? When a holistic view of the roofing system is not accounted for in the design, other, more project relative design elements may be overlooked leading to unforeseen issues during construction and in the future.? The effects of these oversights include overdesigned roofing system attachment/uplift design, added project costs, constructability issues, and conflicting / confusing specification requirements.? In an attempt to avoid these consequences this presentation will examine regional design criteria outlined by ASCE 7, Factory Mutual and ANSI/SPRI.? Additionally, it will address specific and common misconceptions and challenges such as the misuse of water based adhesives in single ply applications, FM 1-90, design pressures vs. design wind speeds, extreme warranty requirements, and limitations of certain substrates/decking materials.This presentation is geared towards a commercial audience and is presented at an intermediate to advanced level.

1. Choose a roof design based on your individual project’s needs (building, environment, or project conditions/location).
2. Determine which project relative designs to consider to avoid issues during construction and in the future and which regional design criteria outlined by ASCE 7, Factory Mutual and ANSI/SPRI affect your project.
3. Determine the reality to common misconceptions in the industry and how to address challenges with: FM 1-90, design pressures /wind speeds, warranty requirements, limitations of substrates/decking materials, and more.
