The cost of roof cleaning in the UK varies according to the method of cleaning. The usual methods are:

  • moss removal only – usually by scraping moss from tiles
  • jet washing tiles using water at high pressure to blast the surface clean (also known as pressure washing / power washing – we DO NOT use this method for cleaning roofs**)
  • low pressure roof soft washing

**Although we offer a professional pressure washing service for block paving, driveway and patio cleaning and sealing we do not jet wash roofs as tile manufacturers specifically warn against jet washing roof tiles. It can strip away the protective coating covering the exterior surface of the tile. It can be done safely and there are professional roof cleaning companies that jet wash roofs with excellent results. This post about the cost of cleaning roof tiles is not intended as a criticism of legitimate businesses that use different methods.

However, we prefer to follow the advice of the manufacturers and so don’t use high pressure. For example, Marley Tiles recommend removing moss by scraping and warn against jet washing.

In our experience jet washing roofs is also extremely messy with moss and dirt flying everywhere and can also damage and dislodge tiles. Furthermore, jet washing only removes surface dirt and the black staining seen on roof tiles is usually black algae, called gloeocapsa magma. Some of this algae is absorbed by porous materials such as roof tiles and after pressure washing it will be unaffected and will then recolonise the roof. Soft washing biocide kills all biological spores including algae and lichen above and below the surface, resulting in a far more thorough and effective clean.

We also do not offer roof coatings.

Average prices to clean a roof

London and the south east are typically more expensive than other areas, as are our house prices.

Quotation are a reputable and established website for online quotes and they say that the average price for roof moss removal in London and the south ranges between £700 to £900.
