roof edges

[teo's]

Hello everyone! I am finishing my draft composition and I am encapsulated in the above problem: as you can see from the enclosed pdf, some roof edges in contact with the external walls have disappeared, or to better say they do not appear just, and I can not find the way to make them appear.. Does anyone have any suggestions about this? thanks in advance to those who will help me!

Sorry, but where's the roof?

the roof is that floor, not the typical falde. .
