Roof Treatments

When it comes to roof cleaning, J.K. Aidan are fully equipped to tackle most jobs. Our extendable pole system and scaffold tower means we can take care of your roof without stepping foot on it. Our preferred method is to remove the moss etc from the roof and then apply a biocide (see below for more details). We can also pressure wash the roof for a more instant result but the use of high pressure is not suitable for every occasion. We will advise whichever method we feel is best for your roof and discuss why.

Each and every roof clean comes with its own obstacles, whether that be access issues, weak tiles or it isn't suitable to use products but we have solutions to every problem! 

In general the cleaning process is as follows;

  • The surrounding area to be cleared and protected if needed

  • Scaffold tower to be erected

  • Down pipes to be covered to prevent blockages

  • Using our extendable pole system we would remove moss from (or pressure wash) the roof

  • Sweep any loose moss from the roof

  • Clean all guttering, fascia and soffits and windows if needed

  • Apply chosen product

  • Clean up surrounding area if needed

What is moss, lichen and algae?

Moss

Mosses are small flowerless plants that typically form dense green clumps or mats, often in damp or shady locations. Unlike most plants, moss does not form roots and can grow on paved surfaces and areas where there is no soil. Moss forms from spores that are carried by wind currents and moving water. In most cases moss spores can not form in areas where healthy plants are already growing. Moss growing in your lawn or garden is often a sign of underlying problems in your soil that are weakening your plants and allowing moss to crowd them out. Moss that is removed often regrows unless the growing conditions in the area are improved.

 

Lichen

A lichen, or lichenised fungus, is actually two organisms functioning as a single, stable unit. Lichens comprise a fungus living in a symbiotic relationship with an alga or cyanobacterium (or both in some instances). There are about 17,000 species of lichen worldwide. Lichens occur from sea level to high alpine elevations, in many environmental conditions, and can grow on almost any surface. Lichens are abundant growing on bark, leaves, mosses, on other lichens, and hanging from branches "living on thin air" (epiphytes) in rain forests and in temperate woodland. They grow on rock, walls, gravestones, roofs, exposed soil surfaces, and in the soil as part of a biological soil crust. Different kinds of lichens have adapted to survive in some of the most extreme environments on Earth: arctic tundra, hot dry deserts, rocky coasts, and toxic slag heaps. They can even live inside solid rock, growing between the grains.

Algae

Algae are a diverse group of aquatic organisms that have the ability to conduct photosynthesis. Certain algae are familiar to most people; for instance, seaweeds (such as kelp or phytoplankton), pond scum or the algal blooms in lakes. However, there exists a vast and varied world of algae that are not only helpful to us, but are critical to our existence. The algae growth on roofs are microorganisms which thrive in moist conditions. They spread by releasing spores into the air. Those spores usually require a moist surface to open. If the moist surface they land on is your roof, that's where they bloom.

Whether it's just a moss removal or a full roof clean and treatment we will; vacuum the gutters, clean the external of the gutters, clean the fascias and soffits.

 

Biocide

A biocide is defined in the European legislation as a chemical substance or microorganism intended to destroy, deter, render harmless, or exert a controlling effect on any harmful organism. 
What Benz say about their roof cleaning biocide (bio Cleanz)

  • Is the powerful active ingredient is a similar purity to that used to disinfect hospitals

  • Can be used in conjunction with power washing as a post-treatment, or as a stand alone softwash solution

  • Fully biodegradable

  • Does not bio-accumulate

  • Ph neutral, so safe for materials and gentle on people

  • Controls algae, lichen, fungi, moss and mould

  • Is safe for children and pets once treated surface is completely dry

  • Non-bleaching (contains no bleach or acids)

  • Harmless to all known building materials

  • Can be used as a pre-painting primer to kill algae and mould spores

  • Helps control wet and dry rot on wooden buildings, sheds, fences and decking

  • Soaks deep into porous surfaces – killing the micro-organisms responsible for unsightly discolouring, and potential structural damage – because of its low surface tension, which makes it an excellent "wetting agent".

  • Up to 8x stronger than biocides sold to the general public

FAQ's

Does it make much mess?

As we are working above the gutter line, any mess or debris is generally caught by the gutters. There may be a bit of moss that falls on the floor but any messing of surfaces will be fully cleaned before we leave. We clear the gutters, wash the fascia and soffits, as well as windows if needed. Plastic sheets will be used if for any reason we suspect too much mess will be made.

Will my roof look like new?

This very much depends on a few factors; the age, condition, type of tiles and treatment chosen (by the customer). What we can promise is that we will get the roof to look as good as it possibly can, subject to the aforementioned contributing factors. 

How long does it take?

This depends on the size, amount of moss to be removed and access requirements. For a 3 bedroom house with a standard roof, we would generally take 1 full day to complete the clean.

How much does it cost?

This very much depends on the factors mentioned above. Depending on the level of service needed prices are as follows; Treatment only: from £5 per square meter, Moss removal only: from £7 per square metre, Moss removal and treatment: from £10 per square metre. For an average 3 bedroom house with moss removal and treatment the price would be around £600.

Our roof treatment process continues to exceed our customers expectations, leaving them 100% satisfied.

To keep your roof moss free and maintain the 'new' look, we recommend a biocide treatment every 18-24 months.
