Clearing moss from a concrete tile roof?

If you want to clear moss off of the roof tiles, ridge tiles and other fittings on the roof a high pressure hose will do the job but beware moss can be quite slippery when wet therefore it could be potentially a very dangerous job to do yourself without the right equipment and tools

If clearing the moss is purely for cosmetic reasons beware that if using a high pressure hose mortar joints could be damaged in the process with the high pressure water blasting away any loose mortar or loose masonry etc. The roof may need some repairs after cleaning the moss off because if the water does break any mortar joints or cause damage it would be best to repair them to save problems with leaks later on
