Cleaning your roof

Clean It are experienced roof cleaners. We know how to remove moss and other organic growth safely, and how to deliver the best possible results for your roof.

Roof cleaning is specialist work because of the tools required, access issues, and chemicals used to provide the best possible job.

Experienced roof cleaners

We have cleaned lots of roofs. We have the knowledge and the specialist equipment to do a pofessional job providing excellent results.

Watch on YouTube some jobs that we did in Worcestershire along with Squeaky Clean Dave.



How we do roof cleaning

Our preferred method of roof cleaning is to scrape and then follow up with a biocide.

We use specially shaped scrapers that match the profile of the tiles. They are attached to the end of a telescopic pole that allows us to scrape the moss off the roof either from the safety of the ground or from a scaffold tower as needed. This removes 90% of the moss from the roof.

We then follow this up with a biocide treatment which removes the rest of the moss and staining. Biocides are powerful and have long-lasting effects. They are applied through a special brush, and then soak into the roof tiles. 

They may take 2-3 months to get the roof to its cleanest state, but then it will keep the roof clean for a long time, sometimes up to 3 years, and further treatments are simple to apply.

We usually use a professional biocde called GK Pro. Learn more about it on their website.

When we come to quote we will be able to assess whether we need a scaffold tower or not for access.

Roof cleaning costs around £12 per m2 of the roof, with a minimum charge of £750 to scrape and biocide. 

When you request a quote we will first give you an estimate based on the size of the roof we can measure on Google Earth. If you are happy with the estimate we will visit to provide you with a more accurate quote.

We do not offer pressure washing as we find it is harsher on the roof tiles and may damage them.

Our preferred method is to scrape most of the moss off and then follow up with a biocide treatment.
