Niigata Prefecture, Japan was hit by heavy snow. What should I do if the snow doesn't reach the roof?

Recently, many places in Japan have been hit by heavy snow, and local people have been seriously affected. The snowfall began on the 7th, which had a serious impact on Niigata Prefecture, Fukui Prefecture and Toyama Prefecture in Japan. Among them, Niigata Prefecture suffered the most, and the snow has not yet reached the roof. Three local people have been killed and another 1 12 people have been injured.

The most commonly used methods to deal with snow are as follows:

First, sprinkle salt.

Under normal circumstances, the roof can directly receive sunlight, and the snow will melt with the sunlight. However, because the newly fallen snow is crisp, like cotton, it can store the heat of the sun and melt quickly, while the first melted snow becomes water, which makes the snow below freeze, not brittle or loose, and it is difficult to store the heat of the sun. So it is difficult to melt the snow on the roof when it melts in half. At this time we can sprinkle salt on the roof to further melt the snow.

Second, raise the indoor temperature.

As a superstructure to protect the house, the roof can effectively resist the damage of the upper snow on the lower floor. However, because it exists above, we can transfer heat to the roof by raising the indoor temperature and flowing warm air (as we all know, hot air flows upward). The rise of the internal temperature of the roof is helpful to melt the snow outside the roof.

Third, wait for natural melting after reinforcement.

In the case of heavy snow, it may threaten the safety of the house itself. In this case, it is very dangerous to melt snow blindly. Therefore, we should change our thinking, first strengthen the load-bearing part of the house, and then wait for the snow to melt naturally or remove a small amount of snow regularly under the condition of ensuring that the house can bear a lot of snow after reinforcement. Never rush to clear the snow. Before cleaning, it should be determined according to the roof bearing capacity of the proposed building. The purpose of cleaning is to prevent injuries caused by roof collapse and ensure the safety of houses and property in the house. When it is really necessary to organize personnel to clear the snow. First of all, we should fully consider the problem of roof load to prevent people from falling down and causing accidental injuries due to the increase of load when they go to the roof to clear snow.
