Mold on roof

I have a house I bought about 14 months ago that has developed mold on roof. The roof, according to inspection is only 6 yrs old. Is there some way to remove the mold without damaging shingles and creating leaks. I realize that this is cause from moisture but there are no signs from inside attic of moisture issues.

I had this problem on my roof. I used 3/4 water to 1/4 household bleach and dumped it on. I let is set for 25 minutes then rinsed with hose. Read about this on Owens Corning website, so it must not harm shingles. Wal-mart also sells a roof cleaner, can't remember name, that is guaranteed to work and also prevent further mold.
