Flat roofs, terraces and extensions: EPDM, bitumen felt or liquid resin. In Tienen our calls fall into three families.
from our office in Tienen
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.
Our registered office is on Leuvensestraat. We know the Tienen building stock from the inside: grand town houses in the centre with box gutters concealed behind a cornice, post-war houses in concrete tiles now reaching their first renovation, and in the villages farms with vast roofs and fibre cement outbuildings.
What we get called out for in Tienen
In Tienen our calls fall into three families. The first comes from the centre: a box gutter behind the cornice that has been leaking into the wall head for months. The second from the districts of the 1960s and 1970s, where the concrete tiles are all reaching the end of their life at the same time. The third from the villages, where a farm or a shed still carries corrugated sheets and the owner wants to know where he stands before a sale.

Common questions
Pour un devis, la visite à Tienen se fixe en général sous quelques jours ouvrés. Nous partons de Tienen, à 0 km, et nous groupons nos visites par secteur : si un chantier tourne déjà cette semaine à Landen ou Leuven, 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.
