Founder and CEO, Rob Haddock

Hi, I am Rob Haddock. I am a metal roof consultant, author, speaker, inventor and the founder of Colorado Springs-based S-5!, the leading authority on metal roof attachment solutions and inventor of the non-invasive clamps for fastening accessories to standing seam metal roofs. My personal BHAG is to promote metal roofing as the most desired, accepted, user-friendly, most coveted roof in the construction industry globally.

With 48 years of industry experience, I have an unwavering belief that metal roofing is superior to other types of roofing and strongly believe that S-5!’s innovations are making metal the most user-friendly roof type on the market.
I began my work life as a cowboy and rodeo competitor, tending a 5,000-acre ranch in the Colorado mountains―yes, the boots and hat are real. I also worked construction, and at the age of 19, I founded a company that erected pre-engineered steel buildings. That was my introduction to the metal construction industry.

For 15 years, I ran a nationwide steel erection business―Seven States Steel. I became actively involved in industry associations and learned everything I could about metal construction from people who knew way more than I did. I found mentors who encouraged and educated me. Eventually, I became recognized as the go-to-guy for metal roofing.

When I “retired” from construction and began a career as a consultant, it allowed me to share my breadth of industry experience with a wider audience. I have worked on research projects; authored articles and white papers (more than 100 in total); designed training and educational curricula; and studied metal roofing history and applications, both domestically and abroad. Some writings and lectures have been translated into at least 10 languages. Today, I continue in this role as director of the Metal Roof Advisory Group, Ltd., an international consulting firm.

As a consultant, I was often asked to determine why a roof had failed and realized the need for a roof attachment solution. This led to the disruptive technology inventions of S-5! in 1991, creating the opening for a whole new product category and the establishment of another new business. Now, we have a 58,000-square-foot manufacturing facility in North Texas serving international markets in Canada, Australia, Central America, South America, Europe and Asia, with our attachments utilized on 2 million metal roofs worldwide, including the world headquarters of IBM, Google, Apple and NATO.
