     Well, Jeff: If that is the dirtiest roof you'll come across, then have no fear. From the pics, that looks like an everyday thing down here. Simple job. Not knowing the climate up there, use the same mix as anyone else would. Should have no problem getting that guy cleaned up real nice.

Thanks,

I'm in no hurry to do it. From what i've read the temps are not exactly ideal yet. Just barely pushing 50's here and with the dew on the roof in the mornings I don't think the roofs are warm enough yet. I had a nice little chat with Lori today and she's gonna put together some equipment options for me. I explained I don't want to be replacing parts early into the game. I would rather spend a little more $ and get a year under my belt before I have to deal with parts failing while on a job site. Thanks for the advice.

Roger, You and I probably share the most common amount of algae being neighbors. Which route are you thinking of going chemical wise for your roofs? Do you have many wood shakes in your area? We do here in the nicer neighborhoods, but I'm not gonna focus on them for another year or two. Although, There is nothing better than a fresh looking Cedar roof in my mind.
