You sure it's mold or could it be moss or algae?
You can test for mold with Qtips dipped in chlorine bleach and touched onto the shingle. If the "mold" disappears, it's mold.
If you are up there and see it's thicker, then it could be moss. Easy clean there: Oxi Brands O-2 Algae and Mold System, (800) 745-5186, www.theo2system.com.

I saw them using 1 part bleach 9 parts water solution- with a brush on a home improvement show.

Use a power washer with some mildew cleaner, afterward reseal it to keep it protected. They sell the cleaner and sealer at Home Depot.
