From what I can see, it looks like the cleaning is performed well. It's hard to say for sure though, because I've requested before and after pics, and never get them. On the roof, there is significant over spray and splash back all over the HVAC unit and all surrounding areas. I would have been a good idea to wipe that down and not assume that it's on the roof and no one will ever see it. I saw it the day after, and it looked very unprofessional.
