Roof insulation à Wezembeek-Oppem
Insulation of pitched roofs and lofts, from the inside or as sarking. In Wezembeek-Oppem it is rarely an acute leak and almost always a roof at the end of its life.
13 km from our depot in Grimbergen
What that changes here
On the periphery a lot of owners insulate the roof themselves, and that is where we find the most damage: insulation pushed up against the roofing underlay, no air gap at all, a vapour barrier full of gaps. We put the ventilation right first, the insulation after.
Wezembeek-Oppem continues on from Kraainem and Woluwe-Saint-Étienne: quiet districts, wide plots and many roofs from the 1960s and 1970s. It is typically the area where a roof is not broken but finished: the tiles have become brittle and the ridge tiles have worked loose.
What we get called out for in Wezembeek-Oppem
In Wezembeek-Oppem it is rarely an acute leak and almost always a roof at the end of its life. The tiles of the 1960s and 1970s have become brittle, the ridge tiles have worked loose and the roofing underlay — where there is one — has gone hard. It is not an emergency, but it is a conversation better not put off for five years.
Wezembeek-Oppem porte le code postal 1970 et se situe in the eastern periphery of Brussels. Notre équipe part de Grimbergen, à 13 km : nous y planifions l’isolation de toiture en même temps que les chantiers de Kraainem, Woluwe-Saint-Lambert et Zaventem, pour qu’un déplacement serve plusieurs toitures.

Pour un devis, la visite à Wezembeek-Oppem se fixe en général sous quelques jours ouvrés. Nous partons de Grimbergen, à 13 km, et nous groupons nos visites par secteur : si un chantier tourne déjà cette semaine à Kraainem ou Woluwe-Saint-Lambert, cela peut aller plus vite. En cas de fuite active, nous venons d’abord bâcher et sécuriser ; l’isolation de toiture n’est chiffrée qu’ensuite.
In most cases, yes: the insulation is fitted from the inside. Sarking — insulation laid over the roof structure, under the tiles — is only justified if the roof has to be redone anyway. In that case it is the best solution, and the question comes up before the tiles are ordered.
The Flemish and Brussels grants change every year and depend on your situation, the dwelling and the contractor. We supply the invoices and technical data sheets required; the application is made to the relevant body. We do not quote amounts that will no longer be valid in six months.
