Using the latest cleaning technologies, we remove moss, lichen and algae from the roofs of all kinds of commercial properties.

Besides ruining the appearance of your company building, moss can also create serious problems for your business, such as damaged roof tiles and blocked gutters. The latter can lead to an overflow of water from your guttering system, which can cause severe structural damage.

Over time, roof tiles become gradually weaker, as their protective layer is eroded by external factors, such as the weather and pollution. This leads the tiles to become more porous and, ultimately, makes them susceptible to moss, which becomes ingrained in the tile.

The Roof Cleaning Process


The first stage of the roof cleaning process involves removing all the moss by scraping it with a roof tile cleaner and then applying a biocide wash if needed. Once all of the moss has been removed, we will ask you if you want us to apply the biocide wash, which is a highly effective treatment for preventing regrowth. In addition to this, this microbiological liquid will continue to clean your roof tiles for anywhere up to a year after application.
