MS Contractor SA supports you in Geneva and elsewhere in the canton. Let us talk about your project
A roof to rework calls for looking at the covering and the points that keep the roof watertight. MS Contractor SA organises the roofing work in Onex according to what is in place and the elements to keep. A description of the current condition and the result you are looking for helps prepare a concrete discussion about the work.
MS Contractor SA carries out your roofing work in Geneva, with the installation of new roofs and the complete or partial refurbishment of existing roofs.

Preparing the stages of your worksite
Each project starts with an on-site visit in Onex to assess the work precisely. You then receive a detailed offer, item by item, then the work is carried out on the agreed dates, with a single contact from start to finish.
Onex, maintaining the roofs of villa districts and the old village
You are hesitating between repairing a few areas and redoing your roof in Onex. We look at the condition of the tiles, the accessible parts under the covering and the joins concerned. This examination is used to compare the work needed before deciding on its extent.
Refurbishing a roof covering may call for replacing the battens or reworking the underlay, even if part of the timber frame is kept. These items are specified in the offer. Also mention any insulation or attic conversion project so that the work is prepared in the right order.
Can you keep your timber frame while changing all the tiles?
Yes, in most cases. If the wood is sound and correctly sized, the tiles are removed, battens and underlay are replaced, then the roof is covered again. Pieces that need it are strengthened or replaced locally, without reworking the whole structure.
