Flat roof waterproofing à Leuven
Flat roofs, terraces and extensions: EPDM, bitumen felt or liquid resin. Leuven brings us two kinds of client: private owners on the edge of the city, and managers of subdivided buildings in the centre.

What that changes here
In a town house or an apartment block, the leak travels through several floors before it shows and often involves several owners. We work zone by zone with a photo report at each stage — usable by the managing agent and by the insurer alike.
Leuven is a student city with a historic centre and a great many subdivided buildings. That gives very varied roofs within a few streets: protected facades in the centre, terraced houses with small dormers, and at the back a forest of flat roofs over extensions that are rarely maintained.
What we get called out for in Leuven
Leuven brings us two kinds of client: private owners on the edge of the city, and managers of subdivided buildings in the centre. With the latter, the flat roofs over the extensions and the valleys between two buildings come back again and again — precisely the places that get forgotten when a house is divided up.
Leuven porte le code postal 3000 et se situe in the Dyle valley. Notre équipe part de Tienen, à 18 km : nous y planifions l’étanchéité de toit plat en même temps que les chantiers de Wezembeek-Oppem, Zaventem et Overijse, pour qu’un déplacement serve plusieurs toitures.

Common questions
Pour un devis, la visite à Leuven se fixe en général sous quelques jours ouvrés. Nous partons de Tienen, à 18 km, et nous groupons nos visites par secteur : si un chantier tourne déjà cette semaine à Wezembeek-Oppem ou Zaventem, 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.
