We specialise in algae, moss & lichen removal treatments for roof concrete tiles & slates.
We offer two systems when treating roofs:
Here you will have to wait for 3- 12 months for end result.
Why use this system? This system is used for two reasons. The first one being is great for tight budgets as there are no hoists needed to carry out these works which reduce the costs. Secondly, this system is used for sensitive substrates like monocouche which is not strong enough as a material to handle steam cleaning. The system consists of pumping our unique biocide up through a large 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 a year for end results to allow for natural weather systems to wash the algae family from your roof. You can expect the moss ball to blow off & the algae to turn brown & die within the first 8-12 weeks. Finally, the lichen is the last of the family to die off as it produces an acid which allows it to form tightly to the surface. The lichen will dry out after 6 months & naturally wash away over the following 6 months.
This system has its place in our work systems as it is also very useful for treatment where hoists can not reach & it is better than doing nothing as these funguses can call a lot of damage to your roofs over time.
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. Using a hoist, we first treat the roof area with our unique biocide that kills all fungus on the roof surface. 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 roof surface to the way it was laid many years ago.
The steam cleaning is carried out by way of the cherry picker and one of our skilled personnel in the cradle so in most cases, we don’t have to step on the roof. All of our staff are certified to use cherry pickers & for safety reasons, we always use a safety harness while using the cherry picker. The days of running around roofs with roof ladders and no harness are gone for good health & safety reasons. Please be cautious if a company offers to carry out the service of a cherry picker.
After your roof has been professionally cleaned, we will review it for the following reasons:
So when it comes to sealing, we have two systems to offer you.
All our sealers are permeable, transparent and impregnate the surface unlike sacrificial sealers which blister & crack with the heat of the sun.
Please see in the video where dry brick square appears even when the wall is wet. This is the importance of sealing facades to stop water damages.
Here the Nolans Group were involved in the roof cleaning. This was a large project carried over many weeks where we carried out soft wash system to the rear of the building due to no hoists access & to the front we carried out instant result system. We brought back the roof surface to it’s original state lifting the whole look of the building.
