Joining Composite Walls and Composite Roofs

[jd10003]

I think I know the answer to this, but wanted to check and be sure.  

I have a composite roof meeting a composite wall, and I want the plywood and roofing skins of the roof composite to extend past the wall to create an overhang (which will be supported by a custom profile rafter tail object).  Is it possible for some of the skins of the composite roof to extend a couple of feet beyond the edge of the framing skin of the roof?  

I think I have to model the framing of the roof and the sheathing/finish as separate roofs in order to get that overhang that I want, but wanted to see if I'm missing something here.

(For the record, if I do the 2-roof workaround, my wall composite skins won't be cut by the shorter roof structure, so I have to model the wall as two separate walls as well!)

Here's a sloppy version trying it with a structural wall and a finish wall, and a structural roof and finish roof.   You can see how I want the roof sheathing skins to extend past the roof framing skin.  I don't have it all resolved and joining correctly here, but I can get it to work.  But you can imagine it becomes very unwieldy trying to edit and to deal with doors and windows when everything is a "double" wall or "double" roof!  There must be a simpler way???

Did you try this ?

I use a combination of solid element operations and merge. I know the trim to roof is supposed to be cleaner, but it's glitchy over time.

for the roof overhang, it's a combination of a separate roof, and complex profile beams.
