Moss doesn't need much encouragement to spread across a roof, particularly on slopes that stay shaded or damp for long stretches. Once it takes hold it holds water against the tiles rather than letting it drain, which is why most roof cleaners recommend dealing with it before it gets too established.
Moss spores are carried on the wind and will settle on any roof surface that offers the right damp, shaded conditions, which is why a preventive treatment after the initial clean matters as much as the clean itself.
