The Most Simple Gable (Revit File Attached)
The reference roof pictured below looks pretty simple. I was thinking I could model this in no more than 5 minutes.
It took me an hour and 15 minutes.
I've got 3 roofs: the main roof with a 1' overhand over the main footprint, and two gables. The gable on the right over the garage is no problem; a simple join. However, the gable on the left is what caused the slowdown.
Notice how the fascia board is flush all the way around and up the gable:
The main slope is a 5/12 and the gable is 9/12. Notice how the gable join at the corner of the main roof (left green circle).

I had to (despisingly) attach the wall below the gable using an edited profile and not the attach roof tool due to a roof join error.
The inside roof geometry is relatively accurate:
What is the best procedure to model this in the future? How long should this take a Revit modeler? How long does it take you?

This can certainly be done as one roof.

What would you do to remove this part of the roof? It protrudes below the fascia board.
Using a void extrusion works fine to remove. No big deal to do that.
Is there a way to lower the right gable to match the existing roof? See how the fascia board does not line up (this is a big deal)?
Roof Valley not exactly in the corner, but this is probably close/accurate enough. However, having it NOT in the corner makes the fascia board work around much better.
I've never seen a roof made this way. This was a lot better/faster than my way and the geometry is much better. If the right gable cannot be lowered to match the main roofline then I would use a separate roof.
Are you asking about the condition at the fascia corner?
I notice your gable roof is set off slightly from the corner-return when attached. Is this intentional?
Maybe try it as a monolithic roof using Slope Arrows, instead of using 2 roofs that are attached. See sketch boundary below:

Since the right gable protruding out of the main roof so you can define slopes instead of using slope arrows. See attached file. That would clean up the details you pointed out above.
The result:
Your attached revit file works, however, I'm getting an error when I try to do it. Anything special to it?
Nevermind, I figured it out. The line must be split:
This seems like the best method. Thanks.
Edit: I can only get this method working with a Plumb Cut roof. I need a Two Cut - Plumb. That is a deal-breaker.
What makes the two cut not work is the gable on the right over the garage, which can easily be modeled and joined as a separate roof. A void extrusion will be needed to clip the corner as well:
Two-cuts don't work with complex roofs. You could simply keep the roof plumb cut and add a void to cut the bottom. It technically is a two-cut plumb.
