Roof Moss Removal in Luxembourg: Prices and Advice 2026
Table of contents (6)
Why remove moss from your roof in Luxembourg?
The Luxembourg climate, with its abundant rainfall (800–1,000 mm/year) and high humidity, promotes the growth of moss, lichen and algae on roofs. These plants are not just unsightly: they retain moisture, accelerate the deterioration of tiles and slates, and can block gutters.
Regular moss removal (every 3 to 5 years) extends the life of your roof and avoids costly repairs. It is an essential preventive maintenance task in Luxembourg.

Moss removal techniques
Several methods are available depending on the type of roof covering:
Mechanical moss removal (brushing):
- Manual brushing or with a rotating tool to dislodge moss and lichen
- Gentle method, suitable for all types of roof covering
- Complemented by a biocide treatment to kill the roots
Low-pressure cleaning:
- Maximum pressure 80-100 bar (compared to 150-200 bar for high pressure)
- Suitable for clay tiles and slates
- Does not damage fragile materials
High-pressure cleaning:
- Effective but risky on porous materials (natural slates, old tiles)
- Reserved for concrete tiles and robust surfaces
- Not recommended for traditional Luxembourg slates
Waterproofing: long-lasting protection
Applying a waterproofing product after moss removal is strongly recommended in Luxembourg:
- Creates an invisible film that prevents water from penetrating the pores of the material
- Delays the reappearance of moss and lichen (5 to 10 years)
- Improves rainwater runoff
- Does not alter the appearance of the material (colourless waterproofing agent)
Tinted waterproofing products are available to revive the colour of ageing tiles, but they change the appearance of the roof. Be sure to respect the aesthetic rules of your commune.
