Soft Wash Roof Cleaning

We specialise in algae, moss & lichen removal treatments for ground works. We carry out algae treatment on many surfaces at ground level. The process is similar to the work we carry out on the roofs and facades. The results in the pictures above speaks for themselves.

1. Soft Wash System: Here you will have to wait for 4- 12 weeks for end result.

Why use this system? This system is mainly used for tight budgets and use for sensitive substrates like sandstone which, is not strong enough as a material to handle steam cleaning. The system consists of pumping our unique biocide up through an extension pole where we brush the product into the surface which kills all algae, moss & lichen. 

The downside to this system is that you have to wait up to 12 weeks for end results to allow for natural weather systems to wash the algae family from your ground works.  You can expect the algae to turn brown & die within the first 1-4 weeks and as mentioned the end results will be up to 12 weeks.

2. Steam Cleaning & Treatment: For instant results.

So with this system although it is more expensive, we end up with instant results after two to three treatments to the surface. We first treat the ground works area with our unique biocide that kills all fungus on the surfaces.  Then after a short period of allowing the product to work, we lightly steam clean & remove the dead debris. In severe cases, we will have to carry out this process 2-3 times to order to bring back the  surface to it’s original state. 

After your ground works has been professionally cleaned, we will review it for the following reasons: 

  1. To make sure there are no damage to the surface.
  2. All groundworks are washed down & left clean.
  3. Report any cracks in the surface to our client that may need attention.
  4. Report any repointing that may be needed or resanding of the cobble that may be needed.

Algae Spores? 

Algae spores are the little black dots that are usually left when you power wash the surface only without treatment. Even with some treatments, they are very difficult to remove. The spore is the root of the algae & if this is not killed and removed then algae will grow back very quickly. Lucky enough, the Nolans Group biocide kills and removes all spores. We have been asked on many occasions after loosing a job to a cheaper contractor price to return to the same job to remove these spores as inexperienced contractors did not know how to remove the same. Please be careful of cheap services as when you buy a cheap carpet, you know upfront but with this service, you will only find out in the end and then it’s too late. There is normally two types of algae found in Ireland. The first one is where the algae is green and turns black with the heat from the sun & second one is red algae which its colour is due to the pigment phycoerythrin. The red algae is little bit more difficult to remove than the black algae. The Nolans Group can look after all funguses to include algae, moss & lichen.
