Flat roof waterproofing à Asse
Flat roofs, terraces and extensions: EPDM, bitumen felt or liquid resin. In Asse and its villages two subjects stand out: the wind and the corrugated sheets.
12 km from our depot in Grimbergen
What that changes here
On farm outbuildings and sheds it is a matter of large areas with a shallow fall, often with aged bitumen. We probe the insulation first: a new build-up laid over waterlogged insulation lifts within two winters.
Asse and its villages sit in open countryside: less shelter, more wind on the roof verges. We always reinforce the fixings at the verge and the ridge here, and we still find a lot of outbuildings and cowsheds in pre-2001 corrugated sheets.
What we get called out for in Asse
In Asse and its villages two subjects stand out: the wind and the corrugated sheets. The wind means reinforced fixings at the verge and the ridge, every time. The sheets cover cowsheds, lean-tos and garages, and the question that goes with them — asbestos or not — is usually only asked when a sale or a conversion is coming up.
Asse porte le code postal 1730 et se situe in the Pajottenland. Notre équipe part de Grimbergen, à 12 km : nous y planifions l’étanchéité de toit plat en même temps que les chantiers de Dilbeek, Jette et Meise, pour qu’un déplacement serve plusieurs toitures.

Common questions
Pour un devis, la visite à Asse se fixe en général sous quelques jours ouvrés. Nous partons de Grimbergen, à 12 km, et nous groupons nos visites par secteur : si un chantier tourne déjà cette semaine à Dilbeek ou Jette, 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.
