Depending on the weather and environmental factors, copper- the ’active agent’- is carried to the surface of the copper wire at a rate of 0.5-1 thousandth of a millimetre per year. In the worst-case scenario, the copper is all used up after 50 years. However, in practice, you can expect a life expectancy between 50 and 100 years.
MOOSfree® doesn’t present any danger where lightening protection system is concerned. If lightning conductor is in place, MOOSfree® tape must be attached to it. As a rule of thumb, all electric parts, that conduct electricity, longer than 2m and closer to a lightening conductor than 50cm, must be attached to it. Copper saddle clamps, available on our website, should be used to attach MOOSfree® tapes to the lightning conductor. Please see MOUNTING INSTRUCTIONS for guidance on how to do it.
MOOSfree®115 is designed for cleaning roof areas with the rafter length of up to 10m and therefore, it is suitable for nearly every home. When used in combination with MOOSfree®30 directly onto the roof ridge, the rafter length to be cleaned is further increased by one to two meters. This combination is much more cost effective, than using MOOSfree®170 alone.
MOOSfree® 30 is primarily designed for mounting directly onto the roof ridge. A roof surface of up to 1 m on either side of the ridge is kept free of moss. This means, that you can mount the standard MOOSfree®115 tape on the second or third row of roof tiles rather than on the first row below the roof ridge.
There is a whole range of coatings and special paints on the market, which protect gutters made of titanium zinc from the effects of pitting corrosion when using copper. Please contact your local retailer and ask for the advise on which product is best for coating. Outdoors Solutions Ltd cannot be responsible for the quality and the effect of the coating being used. The best technical solution is to use copper gutters. Copper is, by far, the most sophisticated material.
Generally, you should note that you might need at least 10–15% more tape if your roof tiles are corrugated. The length of the tape needed should be calculated with the tile corrugation in mind. It is not necessary when your roof tiles are flat. Furthermore, MOOSfree® should be applied onto every area, where free water flaw from the top of the roof is obstructed, for example, at the bottom of the dormers, flat roof windows or ventilators. Please see MOUNTING INSTRUCTIONS for further guidance.
Fleece, a non-rotting textile, is built in between the layers of copper weave. With its ability to hold water and therefore to keep the copper surface moist for as long as possible, it nearly doubles the speed of the cleaning process.
If you need to change a single roof tile, which has MOOSfree® attached to it, you should cut the tape out, using scissors or a suitable knife, in places, where the tile meets the neighbouring tiles. Once the new tile is in place, the tape can then be removed from the old one and attached again back onto the new one. If the self-adhesive tape is damaged during the process, we will be happy to send you a replacement tape.
The whole roof does not necessarily have to be cleaned before mounting MOOSfree®. However, the Requirements for Mounting must be fulfilled for the area where it is to be applied. If your roof is covered with a thick layer of moss, it should be given at least a basic cleaning before mounting MOOSfree®, so that the excess of removed moss do not block the gutters.
The self-cleaning process starts six to eight weeks after mounting MOOSfree®. Cushions of lightly attached moss are the first to be removed after dying. Fungi and algae, lying deep in the coarse surface of concrete tiles, take longer to be eradicated. This process is enhanced by natural atmospheric conditions (heavy showers, sleet, hail stones or snow). Generally, the process is complete after two to four years. Of course, the material the tiles are made of, along with the type of surface, original condition, climate and environmental conditions all make an important difference to the length of the self-cleaning process.
Generally, MOOSfree® can be mounted at any time of the year, as long as the Requirements for Mounting are observed. However, moss can be best attacked in spring and autumn, because during those seasons, moss blossoms particularly well, given the weather conditions, lots of rain and little sunshine. Luckily, it is also in this type of weather that MOOSfree® produces the most cleaning copper ions. In winter, dead moss is mechanically removed by the snow and ice that forms and slides over it. If you decide to apply MOOSfree® tape in winter, you should be able to see the effects of the self-cleaning the following spring.
