I have the project attached, and I cannot get the join in Section 2 (screenshot attached) to cleanup correctly. I suppose I could just make two roofs on top of each other, one roof extending to the wall exterior, and the other roof extending to the wall interior, but I do not find that to be an elegant solution.
Does anyone know a better way to do this (using the roof/wall structure priorities?), or is the "2 roofs on top of each other" the regular go-to solution for these cases, just like people usually model the finish floor on top of the structural floor?
Many thanks.

Unlock the Wall Layers you want to adjust independent of the other Wall Layers
Thanks for the suggestion. I also thought of that, but the problem is that the walls are attached to the roof and the roof has a funny slope. I tried this technique, but I was not able to make it work: when attached to a roof, the handles to adjust the particular wall layers do not become visible so that I can manipulate them...
I attached the 2 pictures to illustrate how shape handles do not seem to appear for the wall attached to the roof, even though they do appear for the same wall type, but just not attached to anything.
I think actually this is intended behavior since in the help link you provided there is a Note in the "Layer extension" section: "Layer extension does not work for walls attached to other elements, such as roofs, ceilings, or floors."
See attached Revit model. You had your roof rock wool set to thermal/air layer (3) as well as your wall rock wool. Since both will be the same function, they will intersect each other. I changed the roof rock wool to function Finish 2 (5). The two will not intersect but now the interior finish will go through.

Yeah, shape handles are deactivated when wall is Attached. Don't Attach. Join Geometries of Wall and Roof. That work?
By following KJSKOOG's suggestion and taking it a step further I was able to get the cleanup I needed (picture attached). Nevertheless, while it worked (somehow) I am still not clear how these layer priorities work:
First of all, you guys seem to be using the layer types quite liberally and seem to be only interested in the priority, and not in the layer type (substrate, finish, ...); e.g. the roof rock wool layer definitelly fits better as a thermal/air layer (from a type/function POV), yet you have no problem setting it as "Finish".
Second of all I got this condition by setting
- the roof rock wool layer to finish [4]
- the wall exterior final layer to finish [4]
- the wall interior final layer to finish [5]
So then it is clear that the roof rock wool layer [4] will cut through the wall interior final layer [5] (because it has higher prio)
But it is not clear why now it will not cut through the final exterior layer of the wall, since they have the same priority. How does Revit decide which has precedence? The "Switch join order" tool seems to do nothing here to change the way that the same prio layers cut each other (I think that would be the purpose of this tool). The wall and roof seem to be anyway not joined (becuse the roof does not get selected when I choose "Select Joined Elements" from the wall context menu), and using the Join Geometry tool on them has also no effect (no change in the "Select Joined Elements" result)
Yes, priority gets you what you are looking for for what is cut where and what order, but usually any thermal/ airspace is within the wall between the interior and exterior finishes. The core I set up as framing type then go from there for the exterior and interior sides. The finish side of all interior walls I use finish {5} and exterior finishes I use finish {4}. Sometimes you need to think against the grain to get what you want from Revit.
