Flat roof waterproofing à Jette
Flat roofs, terraces and extensions: EPDM, bitumen felt or liquid resin. In Jette the interwar roofs are starting their second life.
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.
Jette is largely interwar: terraced and semi-detached houses from the 1920s and 1930s, in clay tile or first-generation concrete tile, with dormers added later. Towards the Laerbeek wood the gardens get bigger and the slopes become shadier.
What we get called out for in Jette
In Jette the interwar roofs are starting their second life. We are called about tiles that have become brittle, about dormers added later and never properly flashed in, and about gutters giving up after eighty years. Rarely an emergency, often a roof that is finished.

Common questions
Pour un devis, la visite à Jette 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 Molenbeek-Saint-Jean ou Schaerbeek, 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.
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.
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.
