Selecting a Snow Guard--Which snow guard is right for your house?

摘要

Snow guards are L-shaped devices attached to sloped roofs that prevent large sheets of snow and ice from ava-lanching off them. They suspend precipitation in a holding field, then let it slowly and safely drop off in small amounts or melt completely. While they can be installed anywhere on roof surfaces, it is especially important to install them above entryways, walkways and gathering spots. This prevents extensive damage to property and people.Snow guards help prevent ice damming at a roof's edge and gutter damage. If a gutter has a face higher than the pan of the roof panels, the gutter must be protected from sliding ice and snow. Gutters are designed for one purpose: channel the water to a downspout. They do not serve a secondary function as a snow guard; they will not hold ice and snow on the roof.
