Both chemical and biological moss removers typically serve two purposes:

  • Soften moss (then it can be removed more easily)
  • Disinfect the roof

Chemical moss removers have the advantage of preventing the roof from getting dirty again quickly. However, they can have a strong impact on the environment through the chemical substances they contain.

Tips

Most (chemical) moss removers for the roof are based on copper sulphate.

In contrast, biological moss removers are much more environmentally friendly. Without exception, they contain biological components, so they do not require any chemicals. There are no real disadvantages.

The easiest to use is a spray bottle. With a corresponding product, all you have to do is turn or remove the cap and you can spray on straight away.

Tips

Extensions are often available for spray devices so that you can even apply the respective agent from the ground.

A canister with a pouring spout proves to be very practical in practice. Dosing is easy thanks to the spout.

Moss removers in normal bottles or canisters without a pouring spout are less recommended. Such containers require some accessories, such as a watering can, for use.

When buying a moss remover for the roof, you should consider other criteria in addition to the specific type (chemical or biological, container):

  • field of use
  • ingredients
  • fertility
  • Long-term effect

field of use

The moss remover must really be intended for the intended use, the removal of moss from the roof.

Attention: So-called moss destroyers (€ 8.11 at Amazon *) are used to kill moss on lawns or green areas. They are NOT suitable for roofs, terraces etc.

ingredients

Choose a product that is acid and chlorine free and pH neutral.

fertility

The moss remover should be as economical as possible. When comparing several products, take into account the manufacturer's information on this aspect (which area does the remover cover? Only 100 or even 400 square meters?).

Long-term effect

Ideally, the moss remover prevents moss from re-colonizing for a long time.

  • coarse or rotating brush (for mechanical removal of the moss after it has softened)
  • High-pressure cleaner (€ 89.00 at Amazon *) (NOT for mineral roofing such as bricks, cement and the like)
  • Safety equipment (scaffolding and belt when climbing onto the roof)

frequently asked Questions

Does it make sense to remove moss from the roof?

Yes and no. The experts disagree on this question.

Opinion 1: The moisture stored in the moss damages the roof (possible mold infestation of the roof structure, clogging of the gutter by loosened moss).

Opinion 2: Moss prevents rainwater from flowing off and prevents the sewer system from overflowing in heavy rain.

How do I use the moss remover on the roof correctly?

  1. Apply moss remover according to the manufacturer's instructions.
  2. Leave to act long enough (observe manufacturer's instructions).
  3. In the case of severe infestation, remove the loosened moss mechanically - with a brush, broom or high-pressure cleaner.

How much does a moss remover for the roof cost?

Solid moss removers for the roof are available from around five euros.
