Roof Cleaning - Treatment & Sealing​

Roof cleaning is a crucial component of regular house and roof maintenance, as well as external cleaning services. In the future, failing to get your roof properly cleaned on a regular basis may need a variety of expensive repairs.

Our Expert Roof Cleaning Services

We specialise in algae, moss & lichen removal treatments for roof concrete tiles & slates. Our skilled team of specialists at Nolan’s provides two kinds of roof cleaning services:

  • Soft Wash System:
  • Steam Cleaning & Treatment:

Here is a quick overview of both services and the reasons it is crucial to have your home and business roofs cleaned by experts.

Soft Wash System

You will have to wait three to twelve months for the final result in this case.

Why Use This Method?

This roof cleaning system serves two functions.

The first option is ideal for households with few resources since it eliminates the need for hoists, which lowers the expense of the work.

Second, this approach is utilised for delicate substrates like monocouche since it lacks the material strength to withstand steam cleaning. The method involves brushing our special biocide into the surface after pumping it up through a long extension pole, where it destroys all algae, moss, and lichen.

We specialize in a low-pressure roof cleaning system that thoroughly yet gently cleans even the most fragile shingles and tiles. It is very helpful for treating areas that hoists cannot access and because it is preferable to take action than to do nothing because these funguses can cause significant harm to your roofs over time.

Steam Cleaning & Treatment

This roof cleaning system is 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:

  1. To make sure there are no hip/ridge tiles needed to be rebedded.
  2. Check there are no loose or slip tiles on your roof.
  3. All your gutters are cleaned out & water tested where we will report any leaks.
  4. All facades & groundworks are washed down & left clean.


  1. Asks the contractor how is your roof is going to be cleaned safely & can I see a copy of your method statement.
  2. Does your product you are using kill all algae spores in writing? May I have a copy?
  3. If it’s a slate roof, how will it be cleaned without anybody walking on it which will break slates?
  4. Which is the best system to use for your budget in mind.

Coillete Project HQ 

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.
