MossGo Pro Remove Moss Algae & Lichen

Cleaning Solutions for Roofs & External Surfaces

MossGo Pro removes all moss, algae and lichen problems.

MossGo Pro is a biocide

It kills micro-organisms which colonise external surfaces. This includes viruses, bacteria and algae. When the algae within the lichen and moss die, the whole organism dies and disappears without reproducing. Cleaning tiles using MossGo Pro is the most durable solution.

How long does MossGo Pro take to act?

MossGo Pro is a "soft" and gentle treatment designed to remove growth safely without causing damage to external surfaces. It starts to act immediately and usually begins to produces results within 24 hours but some organisms with will take a little more time to wither away. Although it takes longer than aggressive roof cleaning methods such as power jetting or scraping, it produces better results and no damage to roof surfaces.

moss usually begins to wither within 24 hours. They usually start falling down within a few days depending on the exposure to wind and rain. moss balls will continue to fall until the last one. A wire balloon should be fitted at down pipe inlets to prevent blockage.

algae dies almost immediately. If the layer is thick, a white discolouration takes place within a day or so. Dead algae are rapidly dispersed. Rendered external surfaces in coastal environments are also cleaned from red algae.

lichen are well-encrusted and take a little longer to fall away. Dead lichen become soggy with rain, and curl when dry. After many cycles they finally drop. Cleaning lichen without damaging the substrate is a patient undertaking. Dark background discoloration on concrete tiles washes away over a period of several weeks.

dark background discoloration washes away over a period of several weeks. The rate of disappearance varies with the porosity of the substrate. On concrete tiles the original colour will be recovered in 2 to 6 months. On man made slates the matt brownish layer disappears within 4 to 8 weeks.

Environmental footprint

MossGo Pro is a fast degrading product. 48 hours after application about 85% of the active has already broken down. There is no durable environmental footprint. Short lived as it is MossGo Pro is nevertheless a powerful algaecide, and concentrate should not be allowed to spill in watercourses. If spray drift is likely to be a problem cleaning tiles should be avoided on windy days.

Health & safety

Spray operators should read the Safety Data Sheet, and read the label. The active ingredient has a fairly wide range of applications, under the control of the Health & Safety Executive. The EU Biocidal Product Directive (BPD) defines the scope of application of chemicals. For the purpose of roof cleaning and generally external surfaces, the Product Type 2 (scope of use No 2) applies. Its wording is as follows.

"Used for the disinfection of air, surfaces, materials, equipment and furniture which are not used for direct food or feed contact in private, public or industrial areas, including hospitals, as well as products used as algaecides. Usage areas include swimming pools, aquariums, bathing and other waters, air-conditioning units, walls and floors in health and other institutions, chemical toilets, waste water, hospital waste, soil and other substrates (in playgrounds)."

Safety at work

The issue of safety at work is paramount to roof maintenance. Each site has to be evaluated and safe working methods established. A low pressure telescopic boom can be used for spraying from a roof ladder situated in the centre of a dwelling size roof.
