The reason why I bid via technology is because we have advanced so much that I can see great pictures of your house and roof from google and other sites. Based on what you told me, or the amount of moss and what you needed I was able to generate a bid. There is always more once you get up on the roof and look close, so I base my bid on that and also what you tell me over the phone or via email. Let me know if I can help. Please do not disrespect my business ethics or myself by saying that my bids are too high, unless you run a roof cleaning business. I have been doing this for 10 years and know my field, plus I am a good honest tax paying American. I would love to be the guy who takes care of your roof and does the maintenance, if we can be on the same page. Thanks.
