Why renovate your roof

A sound roof, and extra square metres

A tired roof always ends up costing you: leaks, lost heat, a damaged roof structure. Redoing it is also a chance to gain space in the loft.

No more leaks

New roofing and new zinc work protect the roof timbers and ceilings for decades to come.

Less heat lost

The roof is where a house loses heat most easily. We take the opportunity to insulate it properly.

More light

A dormer or a roof window turns a dark attic into a pleasant living space.

More space

Raising the roof or adding large dormers creates a proper extra storey, without touching the garden.

A style of your own

Standing seam zinc, slate or tiles, timber-clad dormers: the roof changes the look of the whole house.

Roof and interior together

Our teams move straight from roofing to insulation, plastering and finishes: no need to coordinate several contractors.

Our approach

How your project works

  1. Free survey

    We go up to inspect the roof and the roof structure, and we listen to what you want to do with the loft.

  2. Detailed quote

    Roofing, zinc work, dormers, insulation: each item is priced separately so you can compare.

  3. Scaffolding and protection

    Scaffolding around the house, tarpaulins and protection to keep the house dry for the whole duration of the works.

  4. Roof structure and roofing

    Repairs to the roof structure where needed, building the dormers, roofing membrane, then the new roof covering.

  5. Zinc work and finishes

    Gutters, downpipes, chimney and verge cladding, then insulation and interior finishes if planned.

  6. Handover

    We go over the roof and the rooms with you before taking down the scaffolding.

Frequently asked questions

Roofs and dormers: your questions

Do I need planning permission for a dormer or roof raising?

Yes, in most cases you need a building permit from the local council. We tell you which documents to prepare during the survey.

Zinc, slate or tiles: which should I choose?

It depends on the roof pitch, the style of the house and local council rules. Standing seam zinc suits dormers and modern roofs well, while slate remains very common in Luxembourg.

Can we live in the house during the works?

Yes, in the vast majority of cases. The roof is covered up every evening so the house stays dry.

Do you insulate the roof at the same time?

Yes, it is the right moment: we insulate the sloping ceilings with rock wool and redo the plasterwork in the rooms under the roof.

Is the quote free?

Yes, for homeowners within 50 km of our offices: we come and look at the roof and give you a detailed quote, with no obligation.
