Thanks for the advice. Here is a picture of the house. sorry about the snow covering but gives you an idea of how large a roof and the steep pitch with all the dormers. I would rather pay up front to maintain the roof versus doing another shingle job.

Can you tell me if you were succesful with this job? I have the exact same situation in New England. Please see below: Hi, I am looking for some advice and/or a referral. We own a historically important all cedar shingle home in Boston, MA. The house has a massive roof that is severely pitched and measures approximately 40'x120' per side. The house was reshingled about five years ago and the shingles are aging nicely but for the northern facing roof. A slimy green moss has covered the entire roof. During the summer when it is dry, the moss dries out and has a brownish dirty appearance and as soon as it cools down and turns wet, the roof greens up and takes on a mossy, slimy look. It is not a heavy moss coating but rather a thin film. I have had several contractors look at it but once they see the size and pitch of the roof, they never call back. They have all said that they would need to get a bucket truck or lift and then pressure wash. This seems to be a massive undertaiking. Recently I was given other advice and wanted to get the professional's take on this advice. I was told to purchase the Xjet M5 pressure waher attachment and soak the intire roof in Spray and Forget. http://www.sprayandforget.com The idea is that I could use a pressure waher from the ground and with the Xjet spray the solution 40-50' up to the roof ridge and therefore soak the intire roof in this solution. There has been no representation that the roof would look pressure cleaned but rather after several months the moss will have died and I will be left with a mossless roof but it will still retain the aged shingle look. This would be a fine result since the rest of the house is browning up as the shingles age. Does this sound like good advice? If so, will the Xjet attached to a 2400 psi, 2.5gpm washer spray 50' in the air? does Spray and Forget actually work? are there any other solutions other than bleach? Other thoughts? If anyone know of a pro in the Boston area who would tackle this thien that may be the best way to go. Thanks for any help that you can provide!
