Schach Falling in the Wind
Question
In my sukkah, a part of the schach is not tied because it is impossible or very difficult to tie it, since the pergola there is attached to the wall. Occasionally, when the wind gets a bit stronger (but not something out of the ordinary) this schach falls off the sukkah (but not completely because it is tied on the second side) or folds to the side. It does not fly off completely because on the second side it is tied very well. Is the sukkah kosher?
Answer
Shalom and joyous holidays!
A schach that cannot not withstand regular wind is invalid.
Therefore, it is necessary to tie it or place wooden beams that are kosher for sukkah covering on it, which will weigh it down.
