Roof Errors
What sort of roof are you hoping to make? Right now you've got all the segments as Defines Slope (small triangle symbol indicates slope). If you want a flat roof then each segment should not have Defines Slope checked. The plan of the building does not suggest you'll be able to slope every eave of a roof, the notches and bays don't look like they've been conceived of with a sloped roof in mind.

Are you sure the pitch works? Go to elevation and verify by drawing some Ref. Lines.
Start a fresh roof by footprint and sketch the perimeter instead of pick walls...assuming you did that... Also what roof type and settings have been assigned to it?

By Footprint you'd need two roofs. The issue is the interior boundary. Revit doesn't like that condition. They can meet at a corner but you need to break the roof so they aren't a closed loop.

as Steve said it can be done using a join of two roofs
Attached a screencast that is similar to your task....

Still easier than the roof or framer has it... 🙂

You can get there with a single monolithic roof using Modify Sub Elements and 2 Spit Lines.
Thought about that for 10 seconds but I got the impression that the perimeter might not be so simple. If not then the triangulation will be hard to contend with plus getting the pitch set to whatever they want involves a little trigonometry.

Why the snark?
How do you decide how high to move the ridge Split Line up to have a 8/12 pitch roof? It's based on rise/run no? So you need to know the overall width of the roof and calculate it somehow? Sure I can just give it any old offset value but the pitch won't be a "clean number" which will beg the next questioning post...how do I get my slope annotation to read out X:X...and then the answer is change the rounding? Or set the offset accurately?

Suggesting I might be in the wrong business if I need to resort to math seemed snarky to me. It's been my experience that working with roofs and knowing trig (even as little as I know) has been helpful quite a lot.
I don't see how simple it would be to deal with a roof like this with shape editing, no matter how much I like to use the feature.

Well that's a lot better than your first post...
