Plain and simple, moss don't grow where the shines. Without seeing your
house, I'd say that's the root of your problem.
I'll leave the debate over chemical and detergent sprays for everyone
else to fight over, but do you happen to have trees throwing a ton of
shade for most (if not all) of the day onto the moss-infested section of
your roof? If so, having a tree service trim the things back a good bit
will help without having to resort to sprays and other crap that
requires you to not only spend money on a problem guaranteed to
resurface if that's all you do about it, but also climb a ladder or go
walking around on your roof.

Next time you re-shingle your roof, buy anti-moss shingles. You can
limit the moss growth by improving air circulation and light by
removing/trimming nearby trees. There are specific moss-killer
products you can buy but the moss will eventually return. The metal
strips work on new roofs--I have them, they work, but I applied the
strips the year the house was built, 14 years ago.
