While this probably wont be a concern in Los Angeles or Phoenix, it should be a concern if you live in the Midwest, East Coast, or Mountain West regions. When removing ice from the edge of your roof, shovels or hammers won't prove overly useful. Figure 1608.2 is a graphical map that presents snow loads in feet based on the area. information and data gathered from all 50 States. To figure out the load on your roof, take the depth of snow in feet and multiply it by the weight of a cubic foot of snow. The maximum snow load of your roof depends on several factors, but the average roof can support about 20 pounds of snow per square inch. Wind directionality factor in accordance with ASCE 7 Table 26-6. If left on the roof, snow can turn into ice, creating ice dams, a sagging roof, leaks, or even causing the roof to collapse.
