If the condition of your roof is letting down the appearance of your home or building, then we have a safe and highly effective cleaning solution for you.

We can assist you with cleaning your -
  • Coloursteel Roof
  • Metal Tile Roof
  • Butynol Roof
  • Cedar Shingle Roof

  • Corrugated Iron Roof
  • Concrete Tile Roof
  • Chip or Mastic Tile Roof
  • Slate Roof
Please note: Each type of roof surface has its own particular requirements when it comes to cleaning. Some roofs can be safely cleaned by pressure washing or water-blasting, but for other roofs this approach should be avoided, as any form of pressure washing could potentially damage the surface, remove paintwork, or possibly flood the house or building. For these more delicate roofs, a treatment application may be the best and safest solution.

There are also a number of other variables that need to be taken into consideration when approaching a roof clean – the age and state of repair the roof is in, the condition of paintwork, the access available to the roof and the overall level and type of build-up on the roof (moss, mould, lichen etc.) which needs to be removed.

Over the last 14 years, we have developed very effective cleaning procedures for roof cleaning. Depending on your roof type and condition, we may recommend one or both of the cleaning options listed below -

Variable Pressure Chemical Roof Wash

This cleaning process firstly involves the application of our specialist roof cleaning detergents which loosen the dirt, grime and mould build-up on the roof surface. The roof is then pressure washed using low to medium water pressure. This process will leave you with a perfectly clean roof on completion.

  • A Chemical Roof Wash can be suitable for Metal Roofs, Butynol Roofs, Slate Roofs and some Concrete Tile Roofs (if they are in a very sound condition only).

  • We can also apply a treatment to your roof once we have completed the Roof Wash. A treatment application will form a protective barrier on the roof and it will help keep the surface of the roof clean for a much longer period of time. Please see below for details.

Roof Treatment Application

This cleaning process consists of applying our specialist roof treatment product to the roof, which then actively cleans and restores the appearance of the roof gently and gradually over time.

It will typically take between 9-12 months for the roof to become completely clean following the treatment application. We then recommend getting your roof re-treated every two years to keep it looking great.

  • A treatment application is ideally suited for older Concrete Tile Roofs, Chip or Mastic Tile Roofs, Asbestos Roofs, Cedar Shingle Roofs, or any roof which is affected by moss or lichen build-up. A treatment can also be a very good option for new or freshly cleaned roofs, as it will protect the surface from future moss, mould, or lichen growth for up to two years.

Please note: We guarantee the effectiveness of our treatments. If any moss or lichen remains on your roof 12 months after the treatment has been applied, we will return and re-treat any affected areas at no charge.

We would love to transform the appearance of your roof.
