Two major concerns come with the formation of ice on your roof. These are roof collapsing, and the formation of ice dams.
Unfortunately, most unprofessional attempts to remove ice from your roof are more hazardous than beneficial. Reason being, they not only pose a risk for you but also to your roofing structure.
This is where professional roof snow removal in Minneapolis comes in handy. That said, here are considerations to make before starting the snow removal process.
Is it the wet, heavy snow type, or are the fluffy, light and powdery snow? With the wet, heavy snow, you need to act promptly as soon as it hits the 1–1.5 inches height, regardless of whether your roof is flat or pitched. Reason being, anything above this threshold might collapse your roof.
Seeing as the heavy snow weighs approximately ten times more than the fluffy type, this allows you some room for snow removal with the light snow.
One foot of snow on your roof is not a foot of neat and orderly snow that sustains an even depth throughout the roof. Reason being, some parts of the roof may hold a two to three feet depth of snow in the roof.
This mostly occurs in areas where your roof forms a valley, near a dormer, or where the roof joins an exterior wall. These places are under extra pressure, and you should get snow removed first to prevent breakdown.
Flat roofs are always at a greater danger compared to pitched roofs. Reason being, snow hardly leaves a flat roof, even when blown by the wind, it settles on another part of the roof.
Finally, you will find that one section of a flat roof has a 1-foot depth whereas another one has eight feet of snow. The same case applies to a roof that has a shallow pitch.
Always note that, as the snow melts, it does not change its weight, but rather the form. Therefore, if you do not notice any water coming from the scuppers, get a professional ice dam remover to check your drainage system, and steam up any frozen scuppers and drains.
