Flat roof waterproofing à Molenbeek-Saint-Jean
Flat roofs, terraces and extensions: EPDM, bitumen felt or liquid resin. In Molenbeek the first question is almost always access: narrow streets, no room for a scaffold, and a rear that can only be reached through the house.
9 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.
Molenbeek is built dense and low: rows of two-storey workers’ houses, narrow plots, party walls touching one another and, at the back, a run of flat roofs over kitchens and workshops. The real work here is rarely on the slope: almost always at the verge and on the extension.
What we get called out for in Molenbeek-Saint-Jean
In Molenbeek the first question is almost always access: narrow streets, no room for a scaffold, and a rear that can only be reached through the house. Technically it is flat roofs over extensions and the junction between two buildings of different heights — exactly where the water gets in.

Pour un devis, la visite à Molenbeek-Saint-Jean se fixe en général sous quelques jours ouvrés. Nous partons de Grimbergen, à 9 km, et nous groupons nos visites par secteur : si un chantier tourne déjà cette semaine à Brussels ou Jette, 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.
Not always. If the deck is sound and the insulation dry, an overlay is possible and costs considerably less. We always probe the insulation: covering over waterlogged insulation means shutting the problem in for ten years.
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.
