Whoops, fixed it. Thank you!

Have you tried the Split Brep command?
You would then need to check which of the resulting bodies is the one on top and work with the other one.

I tried that, however, there are some elements that aren’t covered by the roof so it doesn’t trim them and creates an error. If I use less cylinders, it works but it still leaves the cylinders extended above the surface.
