How to transition a roof into a wall with a curve?

[GMasis001]

Looking to do something like this where the roof curves up into a curtain wall that has solid panel? The joint between the wall and roof is aligned but I’m looking to curve up rather than meet at a 90degree.

I'd use Roof By [Mass] Face.

Try roof extrusion by profile.
