Here's the best way to solve it

Mechanical cleaning

With a little diligence, moss growth on the roof can be removed using mechanical methods. When working at these heights, you should pay attention to your safety. In addition to scaffolding or a ladder, a belt can help prevent serious accidents.

high pressure cleaner

With a high pressure cleaner(€ 99.99 at Amazon *) remove moss cushions from roof tiles, directing the beam from top to bottom. This will prevent water from getting under the bricks and wetting the insulation. The pressure should be adapted to the sensitivity of the roof covering so that it is not damaged. Processing with asbestos-containing brick panels with these devices is prohibited by law.

Brushes and spatulas

Rotating brushes with coarse attachments are good for removing stubborn growth. If moss has settled in inaccessible spaces, you can scrape off the residue with a spatula.

Flame burners

Flamethrowers and gas burners kill moss cushions down to the roots. To do this, run the flame directly over the vegetation a few times until it is burned. Since this variant carries a certain risk of fire, you should not carry out the work on sunny and hot days. Make sure that no glowing residue falls on the floor.

Combat with home remedies

Vinegar is effective against moss. It usually works faster than chemical products and has a lasting effect. The substance prevents new moss cushions from growing on the roof, at least for the foreseeable future. Spray the moss pillows with a watery vinegar solution, apple or wine vinegar and let the agent work for a day or two. You can then clean the bricks mechanically.

Prevent re-mossing

If the roof cover has been treated with a high-pressure cleaner and brushes, the surface may be roughened. This structure offers optimal growth conditions for new moss cushions because it favors a humid microclimate. It is therefore important that you seal the roof properly after cleaning.
