Flat roof waterproofing à Brussels
Flat roofs, terraces and extensions: EPDM, bitumen felt or liquid resin. In the City of Brussels half the work is done before anyone goes up onto the roof.
10 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.
The City of Brussels runs from the Pentagon to Laeken and Neder-Over-Heembeek: medieval plots with very narrow, very tall houses, 19th-century town houses with concealed box gutters, and further out post-war blocks with flat roofs. On a single job you come across everything — except room to work.
What we get called out for in Brussels
In the City of Brussels half the work is done before anyone goes up onto the roof. Access, permits, occupation of the pavement, the managing agent’s approval: that route sets the schedule. Technically it is most often box gutters, upstands against the neighbouring facade and extension flat roofs — rarely a complete slope.
Brussels porte le code postal 1000 et se situe in the Brussels-Capital Region. Notre équipe part de Grimbergen, à 10 km : nous y planifions l’étanchéité de toit plat en même temps que les chantiers de Molenbeek-Saint-Jean, Schaerbeek et Ixelles, pour qu’un déplacement serve plusieurs toitures.

Pour un devis, la visite à Brussels se fixe en général sous quelques jours ouvrés. Nous partons de Grimbergen, à 10 km, et nous groupons nos visites par secteur : si un chantier tourne déjà cette semaine à Molenbeek-Saint-Jean ou Schaerbeek, 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.
