As you can see the corner is wide open and not boxed in. The top is bot mitered either. Not to mention the shingles were damaged in that area and not repaired. 

All holes should have been addressed by sliding and caulking a small piece of metal between shingles and caulking holes. All exposed nail heads should have been caulked with no problem.

As you can see the metalwork here is the same all around the house. Looks like a 6th grader cut, bent, and installed it.

These shingles should have been cut back and nailed back down.
