I'm learning a ton, but am stuck getting part of my roof to line up.
I'm trying to draw a roof that looks like this:
I currently have this:
Which isn't lining up:
Both of these are draw by footprint with all the angles set to 24 degrees.
I think there be a whole different approach to this to get the tops to align on a specific plane or level, but I'm unsure what to search for.
Thank you so much for any advice on this. I'm stuck and would love a nudge.

These two roofs should not have the same 24 deg slope. The longer is the roof, the shallower the slope so their eaves and peaks can align.
Edit the roof, remove the slope assigned to the sketch line, add a slope arrow and set the head elevation to match the adjacent peak elevation.
I suggest to make it as a single Roof by Footprint...The condition to have equal hights on both walls is that Distance from Wall to Eave to be equal (b value to be the same) as shown in my screen shots.

Wow. This is super helpful. I’m away from my computer but can’t wait to tackle this.
One question. With that larger footprint, it seems that the roof with go inside the rooms. I know there is a cut geometry command but I have t been able to make that work.
Do I need to cut geometry here? If so, is there an example I can see that uses a roof to cut geometry?
thank you very much for explaining the geometry. That is super helpful and gives me the insight to solve this myself in the future.

you are right....Just align the borders with Walls..

Using your advice, I was able to figure it out and learned a bit about geometry too. I'm trying to keep the roofs as one foot print to the maximum extent, but I have one challenge for the final roof line and I think I might be at the edge of what is possible with a footprint. I would love to not extrude a profile, since my roof is covered in snow I can't measure it now.
My roof comes together symmetrically with the slope of the main roof defined by both ends which should look something like this:
But while I was able to get the front section right, the main roof is all off now.
I'm thinking these approaches might work:
(1) make a separate roof for the front bottom right (but then I'm not sure where to put the right side of the gable roof.
(2) extrude a profile.
(3) Use slope line to define the top point
(4) some combination of the single footprint that I'm not seeing.
Thanks for any tips.

is this what you want?
If yes, then have a look at my screencast:

Wow -- elegant solution that preserves the simplicity of a single roof footprint.
Your answer has me wondering if I can measure that offset exactly, but I'll think about that. In any case, it's good to learn about the roof offset capability.
Thank you for the very fast response. You gave me just the nudge I needed to get past the mental block I was having.
you can determine the exact offset making a simple construction in an Elevation or Section View:

I'm stuck after a week of trying to connect two roofs. If I try to join the roof on the right into the other roof, I get 12 errors of "the roof can not be joined". I'm unable to get enough feedback to understand what might be going wrong and how to approach it. There are multiple roofs joined to build out this design, so the joins might be over constrained. If so, I'm not sure how to approach this.
If the Join acts not as is expecting to, then you can extend the small roof into the main one and use a Void Extrusion (Roof or Generic Model in Place) to Cut Off the small one at the joining plan
That roof won't join because it's edge already intersects the face of the other roof. Bring the edge of the roof back a bit until there's some space between the edge and the face of the other roof. then try again. If you're worried about wall attachments/constraints, just fix them up afterwards.
