It is important that you create a separate storey for the roof. You also need to construct a separate room for each roof section in the attic. In this way, many open holes in the roof should be closed, as new walls are always created when constructing a room.

 

If gaps are still visible afterwards, you will have to close these gaps with the help of narrow extrusions. This is not an optimal solution, but it is the only possible one for complex roof constructions.

 

You can only remove overlapping parts with the help of cutouts.
