you only are missing some roof textures there, noggit will show as a plain color textures in wmo's that had weird catclysm flags that are design to overlap a second textures that fades over the first one.
This are made to create the effect of overgrown grass over a building.
In game you should see the whole building without any problems
here is the roof file though.
