For over 35 years, we have been bringing you the best in polycarbonate snow guards for your roof. However, the Snojax I is the one that started it all! This cornerstone of the non-metallic snow guard industry was invented by Jack McMullen in 1976.
Jack had been a metal building dealer for the construction industry for many years. He had seen the materials and methods that homeowners and contractors were using to retain snow. At the time, people in snow areas fought rooftop avalanches by attaching small upright strips of wood or metal across the lower part of their roofs. While these attachments often worked, they led to other troubles for home and building owners alike. Wood would soften and rot while inexpensive cast metal guards would often lead to ugly stains on rooftops. Jack began researching better materials to improve snow guard performance and reliability. Polycarbonate had just recently become available, a clear, UV stabilized thermoplastic resin that has high impact strength and excellent resistance to extreme heat and cold. After testing and prototyping with this new material, the Snojax I was born.
The Snojax I is the “original” clear snow guard designed to be mechanically fastened through the roof panel into a structural purlin or support below. Because of the unique straddling design, they fit most brands of mechanically fastened 36” panels with three 12” flats of four 9” flats. Molded mounting holes are provided in the base of this guard for mechanical fastening and eliminate the need for pre-drilling when used with a self-tapping #14 screw. Because of the narrow design of the feet, adhesive mounting is not recommended. Professional independent testing demonstrated that the Snojax I holds 1,800 pounds when attached with #14 screws. All tests were performed simulating realistic snow loading conditions applied to the face of the guard.
This patented product has stood the test of time and is an aesthetically appealing, low cost solution to the problem of sliding snow and ice on metal roofing. The Snojax I has been a proven and reliable solution for decades and is still popular with our contractors and DIY homeowners alike. The Snojax I remains a staple among the snow guard industry and is still heralded for its high quality and unique styling. This clear guard is still a top seller even after all of these years. We have the originator, Jack McMullen, to thank for that.
