Flat roof waterproofing à Uccle
Flat roofs, terraces and extensions: EPDM, bitumen felt or liquid resin. Uccle is a matter of maintenance, like the green periphery around the city.
15 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.
Uccle is green, large and hilly: villas from the 1920s to the 1970s on big plots, often in natural slate or clay tile, with long slopes and old trees right above them. It is the Brussels municipality where maintenance — leaves, moss, valleys — weighs heaviest.
What we get called out for in Uccle
Uccle is a matter of maintenance, like the green periphery around the city. The calls come in after autumn: leaves in the valleys, moss on the north side, a branch that has broken tiles. Alongside that, the large villa roofs of the 1960s and 1970s are gradually coming round to a full renewal.
Uccle porte le code postal 1180 et se situe in the Brussels-Capital Region. Notre équipe part de Grimbergen, à 15 km : nous y planifions l’étanchéité de toit plat en même temps que les chantiers de Forest, Ixelles et Anderlecht, pour qu’un déplacement serve plusieurs toitures.

Common questions
Pour un devis, la visite à Uccle se fixe en général sous quelques jours ouvrés. Nous partons de Grimbergen, à 15 km, et nous groupons nos visites par secteur : si un chantier tourne déjà cette semaine à Forest ou Ixelles, 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.
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.
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.
