I own a Pressure Washing business located in Davenport Florida and lately my clients have been asking if we can clean their roofs. What's the best product - I don't intend getting on the roof to do this so I'm expecting that the solution I use in addition to a good brushing will remove the dirt. For shingle roofs am I right in thinking that chlorine is the way to go?

Secondly I had a client ask me today to clean his roof but it's one that I haven't come across before. It's actually a vinyl sheet roof - bleach or chlorine? What are your thoughts.

Thirdly - how are you guys getting insured for roof cleaning - I'm getting the run around on this one - any suggestions on this one would be appreciated. It's been suggested to me that I should get the clients to sign an affidavit saying that if the roof leaks or is damaged in anyway that I am not responsible but this seems to be a load of crock to me - surely this isn't the way to run a business???

I'm on a roll so I'll add one more question - we do a lot of manufactured homes and mostly these are the clients asking to have their roofs cleaned - any idea of what I should charge - I was think in the vicinity of $60 but does this seem to little or too much?
