Two separate roofs at different levels and 'connect' them.
Actually I find it easier to do with single roof planes as you have more control of how they overlap each other and how they display on plan.
You can get close with 2 Multi-plane roofs but I find I split them into single planes and do some final manipulating.
You may actually be happy with the 2 multi-plane roofs as they are - it all depends how they overlap.
