I have got a small commercial lot that has a metal standing seam roof on the building (2 years old). The building has no gutters though, and a vert, very steep (almost vertical) pitch to the roof. The problem is that the snow will stick to the roof, only to fall to the sidewalks below it in the days following the storm. This leads to a build up of ice on the sidewalks. I cleared the walks to wet pavement yesterday afternoon, and by this morning, there was 2 inches of ice on them. When the sun comes out in the afternoon, and melts the snow and ice, it then drips on the sidewalk, and at night it re-freezes. So, what can be done to help reduce the ice buildup? It is a relativly new concrete walkway. I have used a good amount of de-icer on them, but it just does not work well on 2" of ice. I know that the obvious soultion is gutters on the building.
