It’s not angled up the sidewall. Look at the building wrap. Building wrap is installed horizontally and the image shows it parallel to the counter flashing and flashing, which means the roof/sidewall intersection, counter flashing, and flashing are also all horizontal.

So, the image is supposed to portray a “headwall” not a “sidewll?
@gromicko The 2nd & 3rd images I posted above are from the NACHI Library. They both show headwall flashing with a roof that is sloped away from the wall. I just spent some time looking for an architectural detail depicting what is in your OP, however the only thing I could find that was even close was a graphic for a flat roof on a parapet wall. Even those show a cant strip to get the water to flow away from the wall. This is from the Nachi library:
I’ve never seen it. If there is a sloped roof at the end of the head wall, like that of a dormer for example, the step flashing on the side wall would extend past the end of the headwall flashing like this picture from one of my inspections (not the greatest picture, but the first one I could easily find):
Now if a roof ends on an exterior wall, the headwall flashing “should” extend past the fascia board slightly, however, again the roof slopes away from the wall, so a kickout in this location would be pointless. Here is another on of mine, warranty inspection (edited for this post), I called this out as a problem because the fascia had slight signs of water damage, even though the roof sloped away from the wall, because the flashing above it did not extend past, and the siding was not cut properly for the flashing.
Yes!
Perhaps this diagram could be repeated left and right (a double diagram), the left side for membrane systems (as pictured) and the right side for shingles or tile.
With Larry’s help, we got it. As I noticed the house wrap in the image is running parallel to the flashing, thus the flashing has to be horizontal (It’s often hard to distinguish an angle from perspective with an actual angle in a 2-dimensional drawing). That established, Larry correctly points out that we can drop the kickback and that it is not a sidewall, but a headwall, and to change the text to headwall. He’s right.
Based on previous notes, we’re trying to depict Sidewall vs. Headwall Flashing. We’ve revised the image noted above and created a new one. Any thoughts? We don’t need to overcomplicate. Our goal is to show components and water flow.
I would make a change to the SIDEWALL image and make the wall and building wrap horizontal. Building wrap does not run parallel to the angled flashing on a sidewall. It runs horizontal.
This is an image created for a commercial use. Would it be okay if we labeled: Flashing (Step or “L” depending on the roof materials)? Many commercial buildings will not have shingles.

And I still think some step flashing is important there depending on actual roof covering material.

The flashing should be step flashing if shingles are used as a roof covering however.
