Sloped Roof Question

[AskArmen]

Hello - I'm a relatively new user, any tips would be appreciated.  Specifically I am trying to achieve the large roof slope effect on the left side of the house (behind the directTV antenna).  How do I configure the roof definition (or the exterior wall definition) to achieve this?  Its a single room underneath.

 

Also the highest roof area with the 4 windows horizontally?  Do I need to create another floor / attic?

 

I am running Home Designer Pro 2025, version 26.2.0.52 macOS

 

Thanks very much - and yes I've already painted the house to improve the color scheme ;)
