There are a lot of short movies on the shell tool in the Archicad YouTube channel.
Link is in the HELP menu.

Create a simple 'Revolved' shell using your roof to set the radius.
This will create a dome but then in 3D select the shell and click on the curve profile line of the dome shape to bring up the pet palette.
Choose the 'Add node' option and the curve will become a straight edge.
Now all you need to do is elevate the shell to match the height of your roof eaves and adjust the apex to match the height of your ridge.

You can use the same composite as your roof - just make sure in the composite settings that the button is set to allow it to be used in a shell otherwise you won't find that composite.

for some reason beyond me knowledge base....I can't seem to get the hang of the shell tool for making this "simple" radius curved roof.

It'd be nice to be able to use a "composite" which I see you can do but...for some reason I'm not getting the right steps on quite how to make this simple slanted, curved roof.

First step is to make sure your roof composite is available to the shell tool.
Press the shell button in the composites settings for the roof composite you want to use.

Now model a revolved shell with your roof composite.
Don't worry about the height yet and use the roof to set the radius and start and end points of the shell revolve.

Select the shell in 3D and make the curved profile straight by adding a node to it.

Now elevate the shell to match the roof and drag the op apex down to match the roof ridge.

Barry...your explanation make it sound "so" simple sir....I hope you are an Archicad instructor where ever you reside.
I'll give it a whirl.

Split the roof into single roof planes and delete bits you don't need now.
You will still have joining lines in plan and elevation but that is because you can't turn of the end lines of the roof or the shell.
That is where the morph comes in handy.
