Flat roof waterproofing à Wezembeek-Oppem
Flat roofs, terraces and extensions: EPDM, bitumen felt or liquid resin. In Wezembeek-Oppem it is rarely an acute leak and almost always a roof at the end of its life.
13 km from our depot in Grimbergen
What that changes here
On the periphery, the flat roofs over extensions and garages are almost always under trees. A single blocked outlet turns the roof into a pond, and that weight of water forces the weak points. Balloon gratings and an overflow matter more here than the membrane itself.
Wezembeek-Oppem continues on from Kraainem and Woluwe-Saint-Étienne: quiet districts, wide plots and many roofs from the 1960s and 1970s. It is typically the area where a roof is not broken but finished: the tiles have become brittle and the ridge tiles have worked loose.
What we get called out for in Wezembeek-Oppem
In Wezembeek-Oppem it is rarely an acute leak and almost always a roof at the end of its life. The tiles of the 1960s and 1970s have become brittle, the ridge tiles have worked loose and the roofing underlay — where there is one — has gone hard. It is not an emergency, but it is a conversation better not put off for five years.

Pour un devis, la visite à Wezembeek-Oppem se fixe en général sous quelques jours ouvrés. Nous partons de Grimbergen, à 13 km, et nous groupons nos visites par secteur : si un chantier tourne déjà cette semaine à Kraainem ou Woluwe-Saint-Lambert, 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.
