There was confusion, I expected that the crew would get on the roof and clean it off. I had asked that the back part of my roof be cleaned, i meant all the roof, not just roof raking. When the gal talked about the kind of rakes they use, I did wonder, but thought it was to make it easier to go onto the roof. Also I think it was Frank raked to the side of the roof , now down at one point. when I asked about it, he said he was only getting the top part. I have since found a piece of shingle on the ground. I has said that they needed to use the standoffs, they had none. when they came, I was going to be out of town next week and felt I had no choice about getting my roof done.
