What that changes here
This is where maintenance pays best. Leaves and moss fill the valleys and send the water under the tiles. Cleaning always includes clearing the valleys and the gutters completely, not just brushing what can be seen from the street.
Zaventem lives with the airport: over the decades many houses have had extra insulation and acoustic work carried out in the roof. That work was not always done carefully, and we regularly find a crushed air gap or a missing vapour barrier.
What we get called out for in Zaventem
In Zaventem it is striking how many enquiries concern what sits under the tiles. Over the years many roofs have had an extra layer of insulation or acoustic work; we get called when damp gets involved. Alongside that, the ordinary work: gutters, roof windows and slopes at the end of their life.
Zaventem porte le code postal 1930 et se situe in the northern periphery of Brussels. Notre équipe part de Grimbergen, à 9 km : nous y planifions le démoussage en même temps que les chantiers de Kraainem, Machelen et Wezembeek-Oppem, pour qu’un déplacement serve plusieurs toitures.

Pour un devis, la visite à Zaventem se fixe en général sous quelques jours ouvrés. Nous partons de Grimbergen, à 9 km, et nous groupons nos visites par secteur : si un chantier tourne déjà cette semaine à Kraainem ou Machelen, cela peut aller plus vite. En cas de fuite active, nous venons d’abord bâcher et sécuriser ; le démoussage n’est chiffrée qu’ensuite.
Every four to six years for an open roof, every two to three years if it is shaded by trees or faces north. Under broadleaf trees, the build-up of leaves counts as much as the moss: it is the leaves that block the valleys and send water under the covering.
Yes, and permanently. High pressure strips the surface, opens up the porosity and forces water under the overlap. The result: the moss comes back twice as fast and tiles work loose in the months that follow. We work by brushing and at low pressure, without exception.
