Benefits of a clean roof

Roof maintenance is essential to the longevity and appearance of your roof. Getting your roof professionally cleaned has a whole host of benefits. The low-pressure high-heat process allows us to give you an expert clean whilst preserving your roof and extending its lifespan. The benefits include:

  • Make your roof look like new, add value to your property
  • Extend the life of your roof by removing damaging growth
  • Allow your roof to breathe and improve circulation

The roof cleaning process

To ensure you receive the best possible service and result, our team follow a 5-stage process. A detailed site survey is undertaken remotely using Google Earth. Using this tool we can get an accurate scope of the work required in order to present you with this quote in the quickest time possible. Depending on the access to your property, the surrounding area and terrain, we will recommend the most suitable access equipment for the job. Once the roof has been cleaned and had it’s biocide treatment, we complete stage 5 by ensuring the your windows and gutters are spotlessly clean. If you have any questions about our process, you can speak with our Exterior Division team.


With our high-heat pressure washing method, we can get through the years of battling with the elements. We can achieve like-new results.


Your roof is safe with our team. We use low-pressure washing with absolute care to ensure even the most aged roofs remain secure.

Biocide Treatment

We apply a biocide treatment to your roof to eliminate the growth of algae, moss, lichens, and fungi over time, increasing your roof’s lifespan.

What is biocide?

Biocide is a chemical treatment that we apply to your roof after the steam cleaning stage.

Its main role is to prevent microbial growth (moss, mould, and algae) and to extend the life of your roof. The combination of biocide and low-pressure high-heat steam means you get a thorough clean paired with long-lasting protection of up to 3 – 5 years.
