The Process of Cleaning a Roof
Roof tiles that are manufactured from clay or concrete can suffer from moss growth, lichen and a general build up of dirt/pollution.
Most of this growth is unsightly, and while it rarely causes any damage to the roof, it is possible to remove it with a high-powered water pressure or manually by using a scraper and a brush.
Roof cleaning has become popular in the United Kingdom over the last decade. This is partly due to an increase in moss growth, which is caused by improvements in air quality. With less moss killing chemicals such as lead in the air, there has been a notable increase in moss growth on roofing tiles.
Once the work has been completed a moss inhibiting chemical treatment can be sprayed onto the tiles to stop the moss from immediately growing again.
Roof Coatings and Sealants
The example quotes below do not include the cost to spray the tiles with a coloured sealant or coating, this price is covered by another page on this site.
Coatings/sealants are optional extras which should only applied to a roof that has been thoroughly cleaned with a pressure washer. They should not be applied to roofs that have moss removed manually as there will still be some dirt and contaminants on the tiles that may prevent the coating from adhering properly.
A Warning From Trading Standards
This type of roofing work is popular among “cowboys” and other unqualified and inexperienced traders. The UK’s Trading Standards have put out several warning notices in recent years, advising homeowners to be wary of roof cleaning and coating cold callers.
The quotes on this page are examples of roof cleaning costs/prices from reputable traders and not door-to-door cold callers.
Example 1 – Cost to Clean a Roof by Pressure Washing
This example cost is to thoroughly clean the roof tiles with a powered pressure washer, which will need to be connected to a power supply and a water connection. Neighbours should be informed that this work is being undertaken as there is likely to be spray and moss being blown onto their property:
- Erect access equipment up to the roof (roof ladders, access towers, ladders, etc.)
- Cover the ground with a cover/tarpaulin
- Clean the roof with a power washer
- Replace any broken tiles and carry out any minor roof repairs
- Treat roof with a chemical moss inhibitor
- Clean up the area and remove all waste
As you can see from the table below, the average cost to pressure wash a roof is £480.00 +vat if applicable.
|Location||Small Business /Trader||Large Business|

|South, SW and Midlands||£450.00||£625.00|
|Outer Region and North||£450.00||£500.00|
Example 2 – Price to Remove Roof Moss Manually With Scraper and Brush
This price is to remove the moss manually with an instrument and a brush, this won’t remove the lichen or the dirt on the roof but the chemicals applied afterwards will take care of this. Manual moss removal may take longer than pressure washing but the clean up afterwards is completed much quicker.
The manual moss removal process involves:
- Erecting ladders and other access equipment to the roof
- Covering the flower beds/patio etc with a tarpaulin
- Remove the moss with a scraper
- Dust off the roof with a brush
- Check the roof for any damage and carry out minor repairs
- Treat the roof with a fungicide chemical treatment
- Clean the site and remove all waste material
This price/cost quote is for a simple “up and over” type roof:

|South, SW and Midlands||£450.00||£600.00|
|Outer Region and North||£400.00||£500.00|
