Flat roof waterproofing à Woluwe-Saint-Lambert
Flat roofs, terraces and extensions: EPDM, bitumen felt or liquid resin. In Woluwe-Saint-Lambert two types of job alternate: the flat roof of an apartment block, with a general meeting, a managing agent and a schedule spread over several months, and the slope of an interwar house, where one call and one visit are enough.

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.
Woluwe-Saint-Lambert combines wide avenues lined with blocks from the 1960s and 1970s with, in the side streets, interwar houses. For us that means alternating between the large flat roofs of jointly owned blocks and the ordinary slopes of single-family houses.

Pour un devis, la visite à Woluwe-Saint-Lambert 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 Kraainem ou Evere, 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.
