Roof moss removal
in Namur
We remove moss and lichen without damaging the tiles, then apply a water-repellent treatment that stops water sitting on the roof and keeps the moss from coming back. We do this in Namur from our base in Walloon Brabant, always with a costing visit before you commit to anything.

The context in Namur
Why here in particular
What changes in Namur is the context: narrow, tall town houses, steep natural slate roofs, zinc fascias. The narrow, steep roofs in the centre call for slate work and careful zinc work, more than simple maintenance.
In Belgium a north-facing slope takes moss within three to five years. Moss holds water, freezes in winter, lifts the tiles and eventually lets damp into the roof timbers.

- Before / after photos handed over with the invoice
Inspection
Condition of the tiles, the ridge tiles, the flashings and the gutters. We photograph everything and show it to you.
Low-pressure cleaning
No 200-bar lance on a porous tile: low pressure, and a rotary brush where it is needed.
Anti-moss treatment
Fungicide applied over the whole surface, contact time respected.
Rinsing and clearing away
Full rinse, gutters cleared, waste taken away.
Water-repellent treatment
A colourless or coloured impregnation that beads water off and slows recolonisation.
Frequently asked questions
Roof moss removal in Namur
The questions we get asked most often before this kind of job.
How long does the water-repellent treatment last?
Between 8 and 10 years on a tile in good condition, less on a tile that is already very porous. We tell you beforehand, not afterwards.
Do you need to be there during the job?
No. Access to an outside tap is enough. You get the photos at the end of the day.
Can a natural slate roof be treated?
Yes, but without a film-forming water-repellent treatment: slate has to stay breathable. We match the product to the material.
Do you come out to Namur with no extra call-out charge?
Yes. Namur is one of our 17 municipalities: the call-out is included in the quote, not added at the bottom of the invoice.

While we are on site
Combining two jobs in one visit brings the invoice down. We suggest it when it makes sense, never to pad the quote.
