Help on a roof

[flikifliki]

Eh guys. So here's my problem. I have found a beautiful house to download on this site. It's the Modern Villa 4 : The Bluesky mansion by !Jolien!. I wanted to download it, but unfortunetly I don't have the addons required... So I decided, by following the floorplans, to build it myself. I started, and it gives me a pretty good result, even though I had a lot of problems during the construction. But I have been able to solve them all, except for one : the roof. If you look at the pictures (front of the house) you will see a room at the second level. Walls are made of wood. I've done this without problems. But I can't get to put the roof correctly. The length of it isn't right, or isn't in the good direction. I've tried many things, but nothing worked. Can somebody help me please ? Does someone had the same problem, and solved it ? Thanks.

Posting pictures of the house they made (or at least linking to it), and of one you're making too, would help.
Of course this will be for your own game only, you can't upload a replicate of an existing upload for same game here.
