Moss on roof


Clean rooftop


We offer a tailored service made up of 3 main steps.

We use telescopic poles and specially designed scraping tools to remove moss, dirt, debris and build up from your roof. Gutters and downpipes are cleaned and cleared as standard along with the rest of the roof's surface. We ensure that the cleaning process is thorough whilst also being gentle to roof tiles.

Protective cleaning and build up prevention for all roofs.

Once cleaning has taken place, the final step in our roof restore service is to spray it with our own chemical biocide DDAC, which soaks into the tile or slate and kills off algae, fungi and bacteria. This chemical will continue to work for up to 12+ months and helps to restore your roofs original colour.
