Wedge sloped roof placement issues

pc

#1

When i try to place Inverted Tiled wedge insulated wooden sloped roof it wont attach to the outside part of the roof, instead its trying to attach to a different piece that is already done and its attaching inside the house inside of outside within other wedges


#2

Same problem no matter what I try I can not get any of the sloped wedge roof objects to point downward only up.


#3

Same problem. Is there a fix?


#4

I also have the same issue, the wedges needs to be able to snap on the sides, and not just on the top/bottom of the piece.
