Roof Cleaning Algae Removal

Lichen and algae on a roof can disturb the flow of rainwater across the roof surface. Growth thrives where the supply of moisture is best and establishes itself where the slates overlap, especially along the lower edge (the tail end) of the slate. It becomes a self-perpetuating problem and this can lead to a host of associated problems.

The main problems are listed below:-

More lichen and algae growth
Water retention by roof tiles – this can lead to damp areas
The roof may look unsightly due to dirt and pollutants
Over time and if left untreated can cause damage to your roof

Roof cleaning service

We prefer to use a process we call “Soft washing”. It is basically chemical cleaning opposed to high-pressure cleaning. The result is instant and penetrates deep and the results are outstanding. This method is far gentler and longer lasting, we use it to clean listed buildings, where the use of high-pressure equipment could damage the surface.

Roof cleaning process

This method we refer to as soft washing uses safe bio-degradable chemicals applied at low pressure so as not to damage the roof. We can also undertake the pressure washing of roofs if the client requests it but this is not something we would recommend. We also undertake other methods of algae removal and control.

Please feel free to contact us for free impartial advice on any aspect of our roof cleaning services.

Why is Roof Cleaning Important?

Gloeocapsa magma is a photosynthetic cyanobacteria consisting of a small group of algae spores. Gloeocapsa magma, inhabits the roofs of houses, feeding off of the limestone filler and the nutrients trapped in the moisture rich shingles. The most beneficial habitat for this particular bacteria involves a humid, damp environment with little access to sunlight. It is responsible for the black/dark green stains that form on roofs. These black stains are the bacteria themselves in mass amounts covering the surface of the roof shingles. Gloeocapsa magma has been around historically and has it been considered to have detrimental effects worthy of prevention.

This cyanobacteria causes substantial destruction revolving around shingle decay and loss of reflective power. Over time, Gloeocapsa magma begins to break down the contents of the shingles by feeding off of the limestone granules embedded in the shingles and this decreases the roof’s ability to reflect ultra-violet rays of light. Also, the quality of the shingles slowly diminishes. They have been found to curl up at the corners as well as form raised humps on the surface. This ultimately can result is broken or disintegrated shingles. In the long run, this has been known to increase air conditioning bills and lead to more frequent roof repair and reconstruction. The main preventative strategy known to date is frequent (annual) roof cleanings using roof algae cleaners.
