I don't want my first post here to be a pitiful cry for help, a quick introduction seems better.  That said I will probably follow this up with many cries for help.  A proper signature is also incoming.

Right off the bat thanks so much for creating this community, I have already benefited from it greatly as a guest. 

After seeing recommendations here Bob from PT did a great job helping me select a small setup to get started.  I did not even end up in the doghouse.  It worked great right out of the box.

After letting too many things get in the way I finally did a little practicing on a family members garage last weekend (pics attached).

Because of how I came to learn about roof cleaning I did not try SH first, I had some spray and regret powder I had purchased and some OxiClean.  I was not quick to try SH because the best price I have so far is 7.39 per gallon.  Based on some very old posts I have come across I believe I need to keep looking for a supply of SH. 

On the first day with the temperature at 45 degrees I applied 40 ounces of OxiClean mixed with 10 gallons of water to the roof.  After close to 40 minutes I rinsed it off and by then it was dark.  The next morning we inspected the work and thought it might have made a difference but we were not completely sure.  One thing I believe you can reliably expect with OxiClean is that anything you do not rinse perfectly will be white the next day

After being completely let down by the OxiClean I was not eager to try the spray and regret product I have and instead went to town to purchase SH to see if roof cleaning really would work as well as you all make it seem.

After an overnight low of 21 degrees and during the mid-day high of 41 degrees I sprayed 5 gallons of gold, I mean SH, and 5 gallons of water onto the roof.  25 minutes later I climbed the ladder to the gutter line and was blown away.  As you can see in the pics the entire house can use some work and I will be back once I solve my SH supply challenge.

I knew immediately that I was going to become a premium member as soon as I got home, I had read about things called surfactants and all kinds of other voodoo I just have to know about.  I am having a great time working my way through the overwhelming amount of information available here.

Again, thank you all, I am looking forward to getting to know everyone.
