This pergola was originally put up a around 2 weeks before Sukkos 5783. The shade that this makes is at least 50/50 (if not more.)
So several questions:
Is this kosher scach by itself? If yes, what about now a year later, the person would have to lift up and put down every small piece of wood to be able to machshir it for this year?
If it's not kosher scach by itself, why? And if a person wants to put up a bamboo sheet (or anything that is yes "kosher scach") on top of it does it "make trouble" the fact that it's there (the beams that are "not kosher" -- for whatever reason.)
If it's kosher scach as it is and the person does not lift up every beam and puts kosher scach on top of it is it a problem?
