Snow Retention System

SNOW SHOULD ONLY FALL ONCE! Snow often accumulates on a sloped roof. When temperatures go above freezing, the snow accumulation melts. Without snow guards and/or gems, the result can be dangerous as the built up snow and ice slides and falls to the ground, and that extraordinary heavy amount of snow could fall onto a person. Help protect your property, your employees and your customers by installing a Sno gem or Snow Guard system. These can be installed on almost all sloped roof surfaces. Let us help provide solutions for your falling ice and snow problem. Here at Diamond Roofing, we have installed several snow-retention system projects and highly recommend to all of our past, current, and future customers.

See story below about a snow-retention system designed specifically for a new elementary school in Ohio.

Alton Hall Elementary School, Galloway, Ohio, recognized the need for snow retention and specified the Sno Barricade from Sno Gem Inc. to be attached to the standing-seam roof.

Providing a safe and healthy environment for students is clearly a high-ranking consideration in the construction of an elementary school. Architects for the Alton Hall Elementary School in Galloway, Ohio, recognized the need for snow retention and specified the Sno Barricade from Sno Gem Inc. to be attached to the standing-seam roof.“We specified the Sno Barricade because of its proven durability and performance,” says Mike Parkinson, associate project manager at SHP Leading Design of Cincinnati. “We’ve used the Sno Barricade on dozens of projects. I can’t remember the last time it wasn’t on one of our projects. The system is designed specifically for each project by Sno Gem. With the design criteria, they run calculations for the project and prescribed a two-rail system around the entire roof to protect the occupants from potential sliding snow and ice.”

With a layout of the standing-seam metal roof, considering slope, length of run, panel width, annual snowfall and other factors, Sno Gem calculates the best snow-retention solution. “Every metal roofing layout is different and each one requires its own calculations,” notes Jim Carpenter, vice president of Operations at Sno Gem. “Our calculations are based on results obtained from extensive testing of our clamps. In addition, we always apply a 2-1 safety factor when calculating a snow-retention system, essentially meaning each Sno Gem recommendation is always twice as strong as the intended system.”

After receiving the design criteria, Sno Gem ran calculations for the project and prescribed a two-rail system around the entire roof.

Employing a 2-to-1 safety factor accounts for unusually strong snow storms—the so-called “one in a hundred year storms.” It’s an inexpensive insurance policy against a rare occurrence.

For the Alton Hall Elementary School, the Sno Barricade was prescribed by Sno Gem. Rush Architectural Metal Erectors Inc. of Washington, Pa., installed 1,850 linear feet of the Sno Barricade around 100 percent of the perimeter of the building. R.A.M.E. also installed the Barricade Plate on Alton Hall. The Barricade Plate is an accessory designed to hold back thinner amounts of ice and snow that could pass beneath the bar. The Barricade Plate is installed on the upslope side of the bar in the middle of the panel. It’s held in place by a tek screw, not visible from the ground. Like the Sno Barricade, the Barricade Plate is available in a color to match any roofing panels.

“Sliding snow and ice is a dangerous problem building owners don’t have to deal with any more because of engineered snow-retention systems,” adds Albert Rush, owner of R.A.M.E. “The Sno Barricade attaches easily and securely without penetrating the panel, so it doesn’t compromise any roofing warranties. The addition of the Barricade Plate provides peace of mind for the occupants, as well as the school district.”
