October 30, 2019 – Chicago, IL – The Metal Construction Association (MCA) 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:
This new comprehensive manual provides the latest code-compliant and market-ready materials, methods, and best practices to re-roof buildings using state-of-the-art metal roofing and light-gauge steel framing systems.
"As metal roof systems are being increasingly used to replace or re-roof over the top of conventional roofing systems, it's more important than ever for building owners, managers, design professionals and contractors to understand how these systems work, and the advantages over other re-roofing methods," explains Mark James, Chairman of MCA's Retrofit Council.
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 1970’s. 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.
"Re-roofing with metal makes even more sense with the current focus on energy savings through efficiency upgrades and the use of renewable energy technologies in the building envelope," James adds.
MCA would like to acknowledge ATAS International, MBCI, McElroy Metal, Metal Sales Manufacturing Corporation, and Roof Hugger LLC for their contributions to this manual.
