Houses in northern rural areas are basically flat-roofed houses, unlike houses in the south and the south, which are all pointed houses, so it seldom snows when it snows. Because of the climate in the north, it snows more in winter, so it is necessary to clean up the snow on the house after it snows.

Houses in the north are flat-topped, which is easy to cause snow. These snows naturally have no influence at first, because they are lightly planted, but after a long time, if they are not cleaned up, the blood will stick to the roof, which means that there is no way to melt the snow stuck to the roof, and then the snow on the roof will gradually penetrate into the house during the melting process, because many old houses in rural areas are not covered with cement, but with white ash. This situation does exist.

On the other hand, it is a question of people's concept, because in the eyes of rural people, if the roof of the house is not swept after snow, it proves that the family is particularly lazy, because rural people know each other, unlike cities, or people in 1 building don't know each other's names, so people care about what others think of them, and the snow on the roof must be cleaned, because it is easy for others to see whether there is snow on the roof.

More for safety reasons, because there is heavy snow in many areas in the north, and the amount of snow is also very large. The snow will be thicker this time. If it is not cleaned for a long time, it will easily lead to water in the house and even affect the possibility of the collapse of the stable structure.
