Founder and CEO, Rob Haddock

Starting out as a metal building erection contractor at age 19, today Rob is a well-known metal roof consultant, author, speaker and inventor. With 45 years of experience in the industry, Rob has an unwavering belief that metal roofing is superior to other types of roofing, and strongly believes that his S-5! innovations are making metal the most user-friendly roof type on the market. “There is simply no other roof to which things can be attached with such ease, economy, and security,” he says.

Back in the 1980s and early ‘90s he was a faculty member of the Roofing Industry Educational Institute and is now an adjunct faculty member at the University of Wisconsin School of Engineering. He has also authored a number of training and educational curricula and, having studied metal roofing history and applications both domestically and abroad, he offers unique insight into this ancient but fascinating field.

For 15 years Rob operated one of the nation’s largest metal roofing companies with some 10 million square feet of successful installations nationwide.  Currently, Rob serves as Director of the Metal Roof Advisory Group, Ltd., a consulting firm performing a variety of services for a worldwide clientele.

Rob has authored numerous articles on metal roofing and gives countless educational talks for various trade groups. His presentations at METALCON and IRE rank as the most widely attended and highly rated year after year.  Rob is an honorary lifetime member of both the MBCEA and MCA.  He is also a charter inductee of the Metal Construction Hall of Fame and recipient of the Carl Cash Award (ASTM), the Richard Horowitz Award (RCI) and the Larry Swaney Award (MCA).
