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.
Our depot is on Vilvoordsesteenweg, so Grimbergen is the municipality where we work most often. It is the typical periphery: a great many detached and semi-detached houses from the 1960s to the 1990s whose roof coverings are reaching the end of their life all at once, and many flat roofs over extensions and garages.

Pour un devis, la visite à Grimbergen se fixe en général sous quelques jours ouvrés. Nous partons de Grimbergen, à 0 km, et nous groupons nos visites par secteur : si un chantier tourne déjà cette semaine à Meise ou Vilvoorde, 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.
