Just a few weeks ago in the upper Midwest, we received over 12 inches of heavy snow in just one storm. It seems an appropriate time to share the important role of snow and ice guards in roofing systems where snowfall is an annual challenge.
Roofing materials such as slate, metal/copper, tile or synthetic materials will not absorb moisture as snow piles up, which leads to the danger of falling ice and snow. Sunlight, gravity and a warm attic will force the heavy snow off your roof in one dangerous event. Decks, sidewalks, landscaping, and other important property and areas of human traffic need protection from these dangers.
One important note: Snow and ice guards should not be installed on asphalt shingle low-slope roofs due to the risk of causing snow dams.
