The Metal Construction Association has published a new design guide, “Retrofit Metal Roofing,” a culmination of practical knowledge and expertise by five of MCA’s member companies that manufacture products relating to retrofit metal roof systems. The 140-page document can be downloaded, at no, cost from MCA’s website at: https://www.metalconstruction.org/Tech-Resources#retrofit_roofing_manual.
This new comprehensive manual provides the latest code-compliant and market-ready materials, methods and best practices to re-roof buildings using metal roofing and light-gauge steel framing systems.
Chapters are dedicated to market history, fundamentals, applications, framing systems, assembly details, metal roofing systems and energy savings. Detailed illustrations show where fully integrated solar hot air and water, as well as power generation photovoltaic equipment, are being incorporated into new metal roof systems.
The implementation of retrofit metal framing systems actually began in the late 1970s. These systems, called “sloped build-up systems,” offer design professionals several options ranging from low-slope functional systems for discharge or diversion of roof rainwater, to steep-slope architectural applications. Retrofit metal roofing has proven to be an economical and functional solution for building owners seeking to beautify an existing structure.
ATAS International, MBCI, McElroy Metal, Metal Sales Manufacturing Corporation and Roof Hugger LLC contributed to this manual.
