Get matched with top roof ice and snow removal pros in Chesterfield, SC

Generally, snow removal from a roof should occur once over six inches of snow accumulates, especially if you notice that ice dams have formed. Without ice dams, you can let the snow accumulation hit 12 inches before removing it. However, the amount of snow that is too much for your roof also depends on the sturdiness of your roof and the compactness of the snow. If your roof needs maintenance or has structural issues, it’s best not to let the snow accumulate too much for fear of collapsing.

There is no hard and fast rule about using a snowblower on a specific amount of inches, but most snow removal experts suggest using one on 2 or more inches of snow for best results. This will also depend on what type of surface you’re working on and whether the snow is dry or wet. 

While it’s less common than on other kinds of roofs, yes, ice dams can form on metal roofs. Metal roofs, particularly those with snow guards installed, can still accumulate ice at the roof edge, although ice dams on metal roofs are less likely to cause roof or interior damage than on traditional asphalt shingle roofs.

A common mistake is you can let snow melt naturally in a window well. However, snow buildup in the well can damage your window frames and walls. The melting snow also poses risks of water damage as it may leak through into the basement. It’s important to shovel snow out of your window wells before too much snow is piled in there.
