14 km from our depot in Grimbergen
What that changes here
Behind almost every Brussels house there is a flat-roofed extension, and behind almost every apartment block a larger area. Access is the problem: the materials go up through the stairwell or over the neighbour’s roof, which needs an agreement. We look at that access on the first visit, not on the day of delivery.
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 l’étanchéité de toit plat en même temps que les chantiers de Uccle, Anderlecht et Ixelles, pour qu’un déplacement serve plusieurs toitures.

Common questions
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 ; l’étanchéité de toit plat n’est chiffrée qu’ensuite.
Yes, and it is often the best first step. We locate the source, give you a time-stamped photo report and a quotation for the repair. Nothing obliges you to give us the work afterwards.
EPDM is laid in a single piece, with no seams across the field of the roof, and lasts thirty to fifty years if it is laid properly: it is the logical choice for an extension or a terrace of normal size. Torch-on bitumen felt still makes sense on large areas and complicated decks. The deck and the actual falls decide, not the catalogue.
