Roof treatment & roof wash

Having your roof cleaned or a roof treatment on a regular basis will help the materials last a lot longer. When it’s not kept clean moss, algae, and atmospheric pollutants will break down the materials and make them deteriorate a lot quicker. The cost of keeping your roof clean is a lot cheaper than needing to replace or do repairs on the roof which can become very costly. When it comes to cleaning your roof we offer two options for having it cleaned.


1. Roof treatment

A roof treatment involves spraying a product onto the roof surface which kills lichen, moss and mould. The rain and sun gradually break down and remove the dead lichen, moss and mould. This process can take up to 12 months or in some cases where there is a thick covering of black mould up to 18 months. Generally results can usually be seen in the first 2 to 3 months with the moss and lichen changing colour.

2. Roof wash and treatment

The second option is where we use our water blasting machines to gently wash away any lichen and algae from your roof. When we do a roof wash we also apply a treatment product which kills the lichen and algae spores and stops them from returning for at least two years. Many water blasting companies don’t apply the treatment after the roof wash and the nasties quickly return and you then need to repeat having your roof washed much sooner.


We wash roofs of all sizes, from a 20msq shed to whopping great big commercial roofs the size of 12 rugby fields.
