    That was an ugly repair… How about squaring it up and making it
    symmetrical and visually appealing at a minimum.

    That is far from a permanent repair. The quality of the cement application
    was a fail and no granules to protect your repair from the weather. That
    repair will not outlast the life of the roof. I would have either torched a
    strip over it or used a modified adhesive with a cotton membrane and
    finished it off with granules. Several years later it would look as if it
    were a new repair. It takes more than just a good product to do good work.
