Samsung or iPhone?

Attach might work. Hard to tell. Have you tried a monolithic roof; let Revit figure it out? She's pretty good at that.

...other ideas: don't do an overhang...offset at plate...raise plate height....butterfly roof....

...if Far Clip is turned off in this view, I might suggest a different roof altogether.
