Massive snow accumulation on the roof can cause unwanted accidents and damage to the roof's resistance structure. Also, because of temperature variations, melting snow can form ice dams on the edge of the roof, preventing water from draining properly and allowing infiltrations.

If you do not remove the snow from your roof, it will also lead to the formation of icicles. They are a real problem that may cause damage to the gutters (the weight of the icicles cannot always be borne by the gutters) and objects they may fall on (e.g. cars).

Icicles appear when the heat from inside the house reaches the space under the roof, warms it and melts the snow. The resulting water flows down and, when it reaches the gutter area, it turns into ice, because gutters are cold and the outside temperatures are very low.

As the rest of the snow on the roof melts, the risks for the building increase: gutters and downspouts get clogged, water is forced to circulate under the tiles and infiltrates in the walls.

Considering the risks of working at height and the amount of snow accumulated on the roof (which may require some hard work!), you should call on snow removal Centennial roofing company specialists to remove it as soon as possible.
