[quote=SniperHF]Have you tried using a different material? I think all the ones used for roof tiling have the word "close" in them but that might just be a D:OS 1 convention.
It's hard to tell by the screenshot, but it is possible that the walls aren't actually closed/linked, in which case the roof will never appear. Sometimes you can have two wall pieces right next to each other that might look right but aren't actually linked.

Just tested. This is Exacly it. Thanks a bunch.
I can now atleast go to bed without having to think about it in my dreams.
