Roofing and insulation
Roofs and insulation that make a house quiet and warm
A roof that stays dry for decades and an envelope that keeps the heat in. The foundation of every sustainable renovation.
Roofing and insulation
Roofing and insulation
We renew pitched roofs with ceramic tiles or slate, lay flat roofs in EPDM or bitumen and handle zinc and leadwork. Roof windows and dormers are installed including interior finishing.
Insulation is approached as a whole: roof, cavity, floor and frames. We pay attention to airtightness and vapour control, so insulating does not lead to damp or condensation.
What we handle
- Pitched roofs: tiles, slate, battens
- Flat roofs: EPDM and bitumen
- Zinc work, gutters and leadwork
- Roof windows and dormers
- Roof, cavity and floor insulation
- Airtightness and vapour control

Frequently asked questions
Are subsidies available for insulation?
Often yes, through national or municipal schemes. We indicate which measures may qualify.
How long does a new roof last?
With ceramic tiles and good zinc work well over forty years; an EPDM roof around thirty.

From shell to keys. One project lead directs structure, services and finishing, so every trade connects to the next.
Construction and extensions
An extension should feel as if it was always there. We build additions and new builds in which structure, glass and finish form one whole.
Foundations
Setting out, reinforcement and concrete to calculation. What goes right here never reappears as a crack in the facade.
