Coloured roof coating
in Genval
On the building stock of Genval — country retreat villas, exposed timber, roofs with deep overhangs, verandas — coloured roof coating calls for an adapted method. A tired roof gets an even colour back and a surface that sheds water, without a full replacement.

The context in Genval
Why here in particular
The damp coming off the water and the wooden roof overhangs call for particular attention to exposed roof timbers. So we adapt the equipment and the method rather than running a standard protocol.
A 25-year-old concrete tile is not necessarily finished: it is faded and porous. Recoating it with a water-repellent product costs a fraction of a re-roof and adds about ten years to its life.

How it runs
How the job runs
The same protocol everywhere, adapted to what the visit reveals on site. Nothing is decided from the pavement.
- Documented porosity test
- Full moss removal first
- Replacing broken tiles (per unit)
- Bonding primer
- Two coats of coloured roof coating
- Protecting the facades and the surrounding area
Porosity diagnosis
An absorption test. If the tile is too far gone, we say no and price a renewal instead.
Full clean
Moss removal and rinsing. Paint over moss does not last six months.
Repairs
Broken tiles replaced, ridge tiles repointed.
Primer
Primer sealer on a porous substrate.
Two coats
Cross-pattern airless application, colour of your choice from the range.
Frequently asked questions
Coloured roof coating in Genval
The questions we get asked most often before this kind of job.
Can natural slate be painted?
No. It has to stay breathable; a film-forming paint makes it flake off.
How long between the cleaning and the painting?
48 h of drying minimum, three days in damp weather.
Does the coating improve waterproofing?
It limits how much water the tile takes in. It does not replace a failed underlay.
Do you come out to Genval with no extra call-out charge?
Yes. Genval is one of our 17 municipalities: the call-out is included in the quote, not added at the bottom of the invoice.
