Professional Roof Cleaning process:-

  • Cover and protect nontreatment roof areas with tarpaulins
  • Block main guttering downpipes
  • Pressure wash roof using fall restraint system for safety 
  • During the cleaning process, the water is continuously pumped from the guttering using our Industrial vacuum
  • Replace all missing, broken, or damaged tiles, re-point / re-bed tiles if required
  • Clean guttering, soffits, fascias, and conservatory (If present!)
  • Unblock downpipes
  • Apply Fungicidal Wash to eliminate any remaining moss spores (invisible to the naked eye)
  • Remove tarpaulins and waste, wash down hard surfaces
  • Window clean using our portable ‘Reach and Wash’ system (utilises pure water)
  • Option to re-colour tiles or protect using a clear coating. Roof coatings have a  life expectancy of in excess of 10 years. At the quotation stage, we can show you coating samples, explain the benefits and supply addresses of completed local projects
  • Option to install Hedgehog Gutter Brush into guttering!
  • Finally remove all waste from the site, as required by law we are Licensed Waste Carriers.

Our Method

With our extensive knowledge and experience, the method we prefer to use is pressure washing. With this system, we achieve instant results without the use of harsh chemicals, adopted by others in this sector.

Pressure washing removes, lichen, algae fungi, dirt, and other pollutants from the roof tiles. The transformation is instant and will reduce long-term maintenance and prolong the life of your roof. 

Does ‘Pressure Washing’ the roof damage the tiles? 

Some companies state pressure washing damages the tiles, this is complete nonsense, pressure washing removes microns Not millimeters if you are at all concerned, why not have the roof coated after the clean? This will increase the thickness of the roof tile prior to the clean.

Why pay out to re-tile a roof? when, very often, a professional roof clean can improve both, the appearance and performance of your roof.


It is not always practical to use articulated booms for access. This is due to the weight of the articulated booms and having to move them over soft landscaping, such as grass, and ornate patios which are not designed to take these heavy loads. 

Great Outdoors Exterior Cleaning Uses the latest Rope Access safety system for Health and Safety. This provides the operator with maximum flexibility to clean the entire roof.

We do not use scaffolding as it provides limited access, and we do not believe in trying to provide an effective clean from the gutter line! 

Great Outdoors Exterior Cleaning carries out free onsite quotations, including a risk assessment. This allows us to inspect the property plus it allows the property owner to ask us any questions directly.
