With the latest version of ASCE 7, Minimum Design Loads For Buildings and Other Structures, wind design for roof systems has become much more challenging for roof system designers and roofing contractors. This paper explores the similarities and differences between the three relevant versions of ASCE 7 and the roofing industry-developed methods to determine loads. It also provides insights regarding the application of the traditional Factor of Safety in various design methods, as well as design enhancements for improved long-term performance.

Cool roofs can help save you money on cooling costs in the North as well as the South. Here are some cool truths to ponder when planning a new roof.* TRUTH 1: It's All About Reflectivity A cool roof reflects the sun's rays away from the roof, helping to reduce rooftop temperatures. While a sunlight-absorbing black roof can reach up to 190°F in the summer, a reflective roof's temperature can be as much as 55°F lower. Dark surfaces also contribute to the urban heat island effect.

Low slope roof penetrations can be a source of problems if not done correctly. Pipe, vent, and conduit penetrations through low slope roof assemblies can cause problems for an otherwise tight membrane, insulation, and deck design. With many intermediate layers in roof assemblies, such as a vapor retarder and cover board, there are opportunities for things not to be done correctly somewhere in the assembly. It gets even more complex when we consider that in order to use a vapor retarder, there might be an additional cementitious board above a steel deck.

Building community. That's what two successful businesses—Accent Roofing and Rhoden Roofing—aim to do throughout the year by boosting their participation in GAF's Habitat for Humanity Contractor program. The concept is simple: roofing contractors volunteer their time, labor, and expertise to a Habitat for Humanity project and GAF donates all of the GAF roofing materials used on the project.
