Please does anyone know how to get the roof tiles/slates in a section to be overlapped the correct way on both sides of the roof structure? When I cut a section viewport, one side (right side in my diagram) of the roof section has the roof cement tiles in the correct overlapping orientation. However, the other side of the roof (left side in my diagram) has the tiles overlapping the wrong way, which would technically means rain water would get under the roof tiles.
