Dyna-Guard is a snow-retention system designed to be used on metal roofs. This system can be installed on a new construction project or retrofitted to an existing metal roof. During installation of Dyna-Guard, either clamps or brackets are attached to the metal roof. Once the clamps or brackets are attached to the metal roof then the Dyna-Guard is bolted to those attachment devices. Dyna-Guard is an 8-foot-long extruded aluminum stick with a T-shape profile. Insert a 2-inch-wide painted strip of metal from the same material as the roof to maximize roof line aesthetics and to provide year-round protection from snow and ice, officials say.
