The ability to extrude a 2d shape in a non-orthogonal direction is what I need.
Create a flat morph surface that is the shape of your desired profiles, one for the eave and a slightly different profile for the gable end.
Then rotate each morph in 3D so that it is perpendicular to the top surface of your roof and then extrude them along the edge of the roof and gable.
No need to extrude along a non-orthoganal direction as you will be extruding perpendicular to the morph surface.
The problem you will have with this is to find the angle that you need to mitre the ends so they join nicely.
You will have to use a zero thickness roof or another flat morph surface that you can get into position to perform a Solid Element Operation with, then hide the operator in a hidden layer.
You could possibly do it with the railing tool.
Use one railing but set a different profile for each segment.
They should mitre automatically, but you will need to know the exact profiles to suit the pitch or your roof so they mitre at the angle you want.
I haven't tried this though and can imagine there may be problems.
