main roof at the garage

[N316RV]

I got most of the roof worked out. It looked great when I only had one story. When I created second story, I have the problem shown on the main roof at the garage. Main roof is 7/12. Garage roof is 12/12. It looks like the main roof is 12/12 at the garage end. I cannot figure out a way to modify this as there is no wall to click on to open and change roof slope. The same question applies to the other end of the house on the front. Without the bump out, I used the cable tool to create a short line to create this cable. Default is the same as the adjacent roof. Is there any way to change that?
Thanks
