It's raining again

Got woken up quite early by some odd noises.
Couldn't quite fathom out what is was.
When I eventually got up and looked out the window, I discovered it was his guy on our neighbour's roof. He was hosing the moss off. Or is he going roof skiing without skis?
She got it done already some time ago, and I believe she had it protected at the time also.
But it obviously wasn't that great, or it wouldn't be needing done again.
It started raining again as he was up there and as I was cleaning my car.
