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.

Bristol — local context

Traditional material: Welsh slate on Georgian terraces, Pennant stone on older buildings.

Clifton Village, Hotwells, and large parts of central Bristol are conservation areas with dense Georgian and early-Victorian terraces where slate re-roofs generally have to match the original material and course.

What changes the price

  • Roof area affected and how heavy the growth is.
  • Access (ladder vs tower).
  • Whether treatment with biocide is included.
  • Whether the valleys and gutters need clearing at the same time.

Timeline: Usually 1 day for a standard semi.

Common questions

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.

What does moss removal / roof cleaning typically cost in Bristol?
