Automated Roofing Error

I was attempting to make a fancy(ish) dorm room for some Hearthlings and this involved a bit of slightly inventive roofing. An error was thrown and the walls did not reach to connect with the ceiling as normal. Error code below, screenshots of building attached. (If anyone knows how to do spoiler text, I’m all ears.) (Also, since new users can only put one image in a post, the other two shall be found immediately below.)
