Gap under roof overhang??

[Davey77]

Just noticed, after numerous wall movements and a couple of room height changes here and there, gaps under the overhang above a 2nd floor bedroom. Hoping somebody can help me with what to look for and/or change to correct what I've created here! I'm not too familiar with all roof aspects. I tried attaching the plan exe but file was too large.

Any and all help greatly appreciated!!

 

Thank you

Dave
