It’s always fascinating to think back on how much Roof Hugger has changed over the years. When my friend and partner Red McConnohie and I started Roof Hugger, our goal was to create something that would allow a new metal roof to be installed over an existing metal roof. It had to work for any new panel, be easy to install, economical and structurally correct. A notched “Zee” seemed to have the most promise. Sounds simple, but there were many challenging issues we had to solve to make Red’s innovative idea a real and marketable product. There was no accepted test protocol when we started, so together with a local engineering firm and local test lab, we created one. A few years later the E-1592 test protocol for metal panels was adopted, setting a new level of sophistication for all our future tests. Actual in place performance tables were established. New corner and edge zone framing assemblies were created to comply with the updated building codes that divided roofs into several distinct zones not just one uniformly loaded roof area. Construction details had to be changed and standard sizes of our sub-purlins had to be modified. All this was a huge change at the time, affecting al
