Question
I have an aluminum pergola that is screwed to the house. Am I allowed to put schach directly on top of the aluminum? Is it that since the aluminum is attached to the house it is like ground, and ground does not receive impurity?
Answer
Shalom Rav
It is forbidden to place schach on aluminum, as it is not suitable for schach.
The permission to place schach on the ground is because it is not customary to use stones for schach. However, materials that are commonly used for schach, like iron and similar, are forbidden to support the schach.
The advice is to place wooden beams on the aluminum, and then place the schach on them.
