Our team explains that basically a roofing ice water shield is an asphalt impregnated membrane that gets applied to the roof deck and then shingled over. When it begins to snow in your area the snow will accumulate on the roof. This kind of placement ensures that the shield protects your roof against leaks and prevent ice dams from forming along the edge of your roof or gutters which are most vulnerable during the winter.

The purpose of snow guards is to hold accumulated snow on the roof until it can slowly melt. This creates a sealed joint that prevent any water that got past the shingles from sitting on the edge of the wooden sheathing or dripping behind the wooden facia board.
