What that changes here
In town, cleaning is as much about the neighbours as about the roof. Water and dirt travel over the party wall, and the rinsing ends up on a pavement or a terrace. We protect the surroundings, work in calm weather and empty the gutters before the end of the job — otherwise all the loosened moss ends up in the downpipe.
Forest is built on a slope, and it shows on the roofs: tall houses from the 1920s and 1930s, a lot of Art Deco around the Altitude Cent, and a low, industrial part down towards the canal. The differences in level make scaffold access the first question on every job.
What we get called out for in Forest
In Forest every quotation starts with access. On the slope of the Altitude Cent the houses are tall and the front gardens narrow; putting up a scaffold there needs a road occupation permit and sometimes a parking ban. After that comes the ordinary work: box gutters, slates and 1930s dormers.
Forest porte le code postal 1190 et se situe in the Brussels-Capital Region. Notre équipe part de Grimbergen, à 14 km : nous y planifions le démoussage en même temps que les chantiers de Uccle, Anderlecht et Ixelles, pour qu’un déplacement serve plusieurs toitures.

Pour un devis, la visite à Forest se fixe en général sous quelques jours ouvrés. Nous partons de Grimbergen, à 14 km, et nous groupons nos visites par secteur : si un chantier tourne déjà cette semaine à Uccle ou Anderlecht, cela peut aller plus vite. En cas de fuite active, nous venons d’abord bâcher et sécuriser ; le démoussage n’est chiffrée qu’ensuite.
On porous concrete tiles or aged fibre cement slates, a water-repellent treatment has a real effect and clearly slows the return of moss. On natural slate it is almost pointless: the stone absorbs practically no water. We tell you that on site rather than selling it on principle.
Every four to six years for an open roof, every two to three years if it is shaded by trees or faces north. Under broadleaf trees, the build-up of leaves counts as much as the moss: it is the leaves that block the valleys and send water under the covering.
