A mossy, streaked roof does not just look neglected — the moss actively damages the tiles and blocks the gutters below. We connect homeowners across Dover, Deal, Folkestone and east Kent with an insured local contractor who cleans roofs safely, without the high pressure that damages tiles, and treats them to stay clear.
Enquiries go to a selected local contractor who assesses the roof and gives you a clear quote. We are not a national firm — you deal with a local contractor who does the work.
Why moss is worth removing
Thick moss holds water against the tiles, so they stay wet and are far more prone to frost damage — freezing water expands and cracks them. Clumps of moss also lift and dislodge tiles, and wash down into the gutters, blocking them and causing the overflows that lead to damp walls. Clearing the moss protects both the roof and the walls below.

Local knowledge
Dover and the east Kent coast get moist, salt-laden air off the Channel that encourages moss and algae to build up on roofs. Many of the area's Victorian, interwar and hillside homes have tiled and slated roofs where moss traps water, lifts tiles and clogs the gutters.

Frequently asked questions
How much does roof cleaning cost in Dover?
Most roof cleans fall between £400 and £1,500 depending on the size and pitch of the roof, how much moss there is, and whether a moss treatment is applied. A quick assessment gives a firm figure.
Does moss actually damage a roof?
Yes. Thick moss holds water against the tiles, which speeds up frost damage and can lift and crack tiles. It also washes down and blocks the gutters, causing overflows and damp. Removing it protects the roof.
Do you use a pressure washer?
No — high pressure strips the protective surface off tiles and can force water under them. A proper roof clean uses careful manual removal and low-pressure softwash, which is safe for the tiles.
Will the moss come back?
Some regrowth is natural, but a biocide moss treatment after cleaning keeps roofs clear for far longer — often several years — before another clean is needed.
