Flat roof waterproofing à Schaerbeek
Flat roofs, terraces and extensions: EPDM, bitumen felt or liquid resin. In Schaerbeek nine calls out of ten are about water coming in through the cornice.
7 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.
Schaerbeek is the municipality of the 1890-1910 town house: tall, narrow facades, ornate cornices, mansard roofs in slate and a box gutter that disappears entirely behind the cornice. Around Josaphat Park and in Terdelt the 1930s are added to that, and their concrete tiles are now reaching the end of their life.
What we get called out for in Schaerbeek
In Schaerbeek nine calls out of ten are about water coming in through the cornice. The town houses there have a box gutter running from wall to wall, often still in lead or in zinc with no expansion joint, with a timber deck underneath quietly rotting. The second most common request is the lower slope of the mansard: slates working loose one after another.
Schaerbeek porte le code postal 1030 et se situe in the Brussels-Capital Region. Notre équipe part de Grimbergen, à 7 km : nous y planifions l’étanchéité de toit plat en même temps que les chantiers de Evere, Brussels et Molenbeek-Saint-Jean, pour qu’un déplacement serve plusieurs toitures.

Pour un devis, la visite à Schaerbeek se fixe en général sous quelques jours ouvrés. Nous partons de Grimbergen, à 7 km, et nous groupons nos visites par secteur : si un chantier tourne déjà cette semaine à Evere ou Brussels, 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.
