What the job involves
Moss grows on the cooler, north-facing side of roofs and in valleys where moisture sits. Light moss is cosmetic. Heavy moss lifts tile edges, blocks valleys, and holds moisture against the covering, which accelerates wear on slate, clay, and concrete.
A professional moss removal is done by hand with a scraper and then treated with a moss-killing biocide to slow regrowth. Power washing a roof is usually a bad idea — it damages concrete tile surface and can force water past laps.

Is moss actually bad for the roof?
Light moss is cosmetic. Heavy moss is a real problem — it lifts tile edges, blocks valleys, and holds moisture against the covering. On a roof already approaching end of life, heavy moss accelerates failure by several years.
Why not just power wash it?
Power washing strips the protective surface from concrete tiles (shortening their life), forces water up under the laps, and can crack slate. Hand removal and biocide treatment is the right approach.
