why s my roof showing in the house??

@christylee1989 Glad to hear that the ceiling is there and that the information helps for future purposes! I would consider myself a 'builder' now as most of the game play that I have focused on for a while now has been creating builds to upload to the gallery. I really love it, but I must tell you that roofs, along with some of the fidgety aspects of the terrain height tools, are some of the more challenging aspects of building that can take a while to get used to plus can be some fussy stuff to work with on a more complex build. So... don't feel bad. They drive many people nuts here and there. 🙂 

This guide has some nice information about roof-building basics that may be helpful: http://www.carls-sims-4-guide.com/tutorials/building/roofs.php
