Snow retention without roof penetration

By The Coffee Shops®.

Learn how clamp-on snow guards provide standing seam metal roofs with snow retention without drilling holes or using set screws.

Snow and ice buildup can cause significant damage to people, property and roofing systems. In climates with heavy snowfall and cold temperatures, roofs must be equipped to weather the elements.

For standing seam metal roof projects, TRA Snow and Sun offers a snow-retention approach designed to preserve the roof’s integrity while providing additional holding power.

The company’s C21 HD and C22 HD clamp-on snow guards attach beneath the standing seam’s hem. Unlike systems that rely on set screws, these clamps require no panel penetration and do not use screws that could loosen, mark the panel or risk damaging the seam over time. Additionally, the HD series clamps are longer than traditional clamps, distributing the weight across more of the roof seam.

Both models are intended for standing seam roofs and can be used in new construction or retrofit applications. The C21 HD and C22 HD are made with 3/16-inch zinc-coated material and are available in raw steel, zinc steel or zinc-plated steel and powder-coated colors. These options allow roofing professionals to consider the system for different project requirements and finishes.

Along with its clamp-on snow guards, TRA Snow and Sun provides free engineered snow-retention layouts. The service includes a custom system design and an engineered placement plan built for the specific roof. Contractors can submit project details to receive a layout for their application.

For contractors working on standing seam metal roofs, the C21 HD and C22 HD offer an option for adding snow retention without drilling into the panels. The systems are designed to support new and retrofit projects while avoiding penetrations that could compromise the roof surface.
