However, it is also possible to drop the snow by its own weight by keeping the roof at a certain angle. Here is a video shot of how the snow is going down with its own weight. It is quiet at the beginning, but eventually falls like an avalanche whether it has exceeded the limit point.

At the beginning it is flat and falling. If you do not look carefully, you will not even notice that the snow is beginning to emerge.
