Roof structure & framing à Brussels
Repairs to rafters, purlins and verges, timber treatment included. In the City of Brussels half the work is done before anyone goes up onto the roof.

What that changes here
Under the Brussels mansard roofs there is an old, slender roof structure, often weakened where the box gutter has leaked for decades. So the damage is almost always on the facade side, in the wall plate and the rafter ends. We open that up before putting a price forward: from below, nothing shows.
The City of Brussels runs from the Pentagon to Laeken and Neder-Over-Heembeek: medieval plots with very narrow, very tall houses, 19th-century town houses with concealed box gutters, and further out post-war blocks with flat roofs. On a single job you come across everything — except room to work.
What we get called out for in Brussels
In the City of Brussels half the work is done before anyone goes up onto the roof. Access, permits, occupation of the pavement, the managing agent’s approval: that route sets the schedule. Technically it is most often box gutters, upstands against the neighbouring facade and extension flat roofs — rarely a complete slope.

Common questions
Pour un devis, la visite à Brussels se fixe en général sous quelques jours ouvrés. Nous partons de Grimbergen, à 10 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 ; la charpente n’est chiffrée qu’ensuite.
A curative treatment carried out properly protects for about ten years. But the real protection is ventilation: a dry, ventilated loft interests neither insects nor fungi. So we put the ventilation right at the same time as the timber.
Four signs should raise the alarm: fine sawdust at the foot of the timbers, exit holes a few millimetres across, timber that sounds hollow under a hammer, and a smell of fungus in the loft. None of them is visible from the ground — which is why we always go up.
