Trying to get rid of Roof Stains?

I have a dark grey roof which has the usual black stains on the shingles. I am looking for the best way that someone has found to get rid of these stains. I can not afford what the roof cleaning companys charge to do it.

I have tried a mixure that a shingle company gave me when I called to ask them. It was 1/4 cup TSP, 1 gal. bleach and 4 gallons of water. This mix helped some and maybe I need to just do it several times.

But before I try again I thought that maybe some of you have a home mix that would work better. Thanks a lot for your help ahead of time.

That mixture is a good one

Roofing shingles can be difficult to clean without damaging the shingles. High water pressure or scrubbing will clean them better but will also shorten the life of the shingle
