Roof moss is usually only an aesthetic problem. Often the roof is not damaged by mossy soil, but it fills in the gutter, and most people think it is beautiful to look at. You can remove the moss so that it does not hold on to the water, and then give it a game of algae.
Moss can hold water on the roof
Moss is typically a problem of purely aesthetic nature. The most common adverse effects are that the moss holds on to the water so that it can sometimes seep in; this is mostly done at low roof slopes. In addition, the moss can wedge between the roof tiles / roof tiles so that they are lifted.
Forms a soil for plants
Another consequence of moss is it can form ground for other plantswhose roots can penetrate the roof. Finally, the moss will often end up in the gutters.

Low-slope roofs are also often characterized by mossy pavements because drainage is not as easy and fast as high-slope roofs.
How to remove mash
If you want to remove moss, it is important that it is done as gently as possible to avoid damage to the roof. The best way is to sweep the moss away with a stiff diet. Do it in the summer after some hot dry weeks so that the roof is as dry as possible.
Use the algae but not the high pressure cleaner
Spray with algae when the roof is clean – a product approved by the Danish EPA. It can usually keep the moss off the roof. Remember to observe all safety regulations when working on the roof.

If you can’t get up to the roof yourself, get a professional company to clean and spray.
Prevent mosquito “attack”
Sun, air and light ensure that the moss does not return. If possible, crop any. trees that shade and sprinkle leaves and branches on the roof. With flat roofs, it is important to direct the water away.

How do you prevent moss on the roof?
If you need to add a new roof, it is a good idea to include moss in the considerations. If you want to avoid moss on the roof, you must apply a roof with a roof slope above 25 degrees. Roofs of less than 25 degrees are more susceptible to attack by moss because more moisture accumulates as the water cannot run off the roof so easily.
Trees and shrubs close to the roof may be the cause of moss on the roof if they shade the roof surface. Prune them so that they do not provide shade for the roof – it reduces the moisture on the roof, reducing the likelihood of the moss reappearing.
