Roof trusses
The service in detail
The roof truss is the structural backbone of every roof – and the heart of our trade as master carpenters.
Whether a classic rafter or purlin truss, modern prefab trusses or the renovation of a historic roof structure: we plan, cut and assemble load-bearing timber structures you can rely on for a lifetime. Every joint is made with the precision and care a master workshop demands.
We build roof trusses in Mertert, Wasserbillig, Grevenmacher, Echternach, Remich, Junglinster and Luxembourg City – and everywhere in between. From the first measurement to the last rafter, everything stays in one hand, with a single point of contact and honest advice.
The finished roof covering is handled, if you wish, by our sister company Blang & Lauterbach. That way you get roof and timberwork from one reliable source – seamlessly coordinated, from the truss to the very last tile.
Variants & options
New roof trusses – traditional & prefab
We build new roof trusses in both techniques: the classic, hand-cut carpenter's truss as well as the industrially prefabricated truss with nail-plate connectors. Which one suits your project depends on the architecture, span and budget – and we advise you honestly.
- Traditional joinery with carpenter's joints
- Prefab nail-plate trusses for wide spans
- Rafter, purlin and collar-beam roofs
- Solid timber and engineered timber (KVH/glulam)
- Precise shop drawings before every cut
Roof-truss renovation
Old roof trusses often suffer from moisture, wood-boring insects or simply age. We inspect the existing structure, replace damaged timbers properly and strengthen the framework – without needlessly tearing down your whole roof. Load-bearing capacity is secured for decades to come.
- On-site inspection and damage assessment
- Replacement of rafters, purlins and beam ends
- Reinforcement and structural upgrading
- Treatment against fungal and insect attack
- Preserving historic fabric wherever possible
Dormers
A dormer brings light, headroom and living space into your roof. We design and fit pitched-roof, gable and flat-roof dormers precisely into your truss – cleanly integrated into the structure and fully prepared for the covering that follows.
- Pitched-roof, gable and flat-roof dormers
- Made to measure and built into the truss
- More living space and daylight in the loft
- Prepared for covering by Blang & Lauterbach

A look at our work
Frequently asked questions
The cost depends on the roof shape, span, timber type and technique – a small rafter truss sits well below a large structure. After an on-site measurement you receive a clear, free quote with no hidden items.
Yes. We inspect your existing structure, replace damaged timbers and strengthen the load-bearing framework. Where possible we preserve the historic fabric rather than tearing down the whole roof.
Very much so. Timber is light, load-bearing and quick to install – ideal for added storeys and extensions. We build these timber-frame structures too; just tell us about your plans.
The cutting is prepared in the workshop, so assembly on site is fast. A typical single-family roof truss is often in place within a few days – we give you the exact timeframe with the quote.
Yes, both are part of our timber programme. From carports to terrace structures and pergolas, we build load-bearing timber in the same master quality as our roof trusses.
Exactly. We build the truss and our sister company Blang & Lauterbach handles the roof covering. That gives you truss and roofing from one source, perfectly coordinated.
