how to remove moss/lichen from roofs permanently?

how do you remove moss/lichen permanently from tiled roofs? Have scraped and used bleach but returns every year!

Fix some bare copper wire along the roof, close to the ridge, with silicon sealant at intervals. The copper will weather and the rain will wash the residue over the tiles, killing moss, lichens etc.

Yes I have the same prob and I've resorted to tree killer! (Deep Root)
I would like to know the answer too!
