Snow Guards are rooftop devices that help prevent snow slides, the dangerous movement of snow and ice, by allowing it to melt completely or drop off in small amounts.  Our clear snow guards help preventdamage from an avalanche while remaining practically invisible, adding beauty and function. Snowguards are a practical, cost-effective addition to any sloped metal roof in winter climates. There are several important factors to consider when selecting the proper snow retention for metal roofing applications. most important features to consider are the height, width and shape of an ice guard or rail system.  determines its ability to hold back layers of heavy ice and snow. A pad style guard should have a flat, forward mounted face that measures at least 3 inches across and stands no less than 2.5 inches high. It must be mounted in the lowest portion of the roofing panel where the snow and ice actually moves, not on a high above the problem area. Snowguards mounted on a high seam will cease to be effective once the frozen precipitation compacts on the panel and becomes lower than the guard
