The posted date helps Jose find people who may be arriving early; there is no chance he gets to you before you arrive.
Speak with Jose about what you want done when he contacts you. He has 2 teams with him. He does wash the roof, but I'm not sure about the roof treatment. I'll ask him tomorrow and let you know when you arrive.
