Over the past year or so quite a lot of moss has grown on my garage
roof. It is pretty much a very big sponge.

I've had some success by shovelling a few spades at a time into a big
container full of water and then gently fishing out the moss with a
rake. But that's nowhere near 100% effective.

Ideas and what should I do next?

Leave it where it is? Whatever you do to remove it is likely to
damage the roofing surface. What harm is it doing?
