How does a roofing project work in Sion?
Initial contact and project scoping
Describe your need via our online form or by phone, specifying the type of work, your address in Sion and your timeline constraints. A roofing professional active in the canton of Valais will contact you within 24 hours to clarify the scope of the project and agree on a site visit date. This step is entirely free and with no obligation.
Site visit and written quote
The tradesperson comes to Sion to assess the situation on site: taking measurements, diagnosing the existing installation and identifying technical and regulatory constraints. After the visit, you receive a written quote detailing every line item of work, materials, quantities and the execution schedule. In Switzerland, an accepted quote is legally binding — be wary of any professional who refuses to put their estimate in writing.
Planning and materials procurement
Once the quote is signed, the tradesperson plans the project around your availability and lead times for materials. For work requiring a permit in the canton of Valais — extensions, facade changes, certain technical installations — they will guide you through the administrative process with the municipal authorities in Sion.
Professional execution to Swiss standards
Work is carried out in accordance with the Swiss standards applicable to the trade: SIA norms for construction and renovation, NIBT for electrical installations, SSIGE standards for plumbing, and AEAI fire protection requirements. The tradesperson keeps you informed of progress and consults you before any technical decision that falls outside the scope of the original quote.
Handover, warranties and compliance documents
On completion, a formal handover is held in Sion to verify that the work matches the quote. The tradesperson issues the final invoice, any compliance certificates required by law (ESTI certificate for electrical work, construction acceptance report) and warranty documentation. The statutory warranty under CO art. 371 covers construction defects for 5 years.

Budget and financing — Roofing in Sion
Estimating the budget for a roofing project in Sion without a proper quote is difficult, but a few benchmarks help. Rates in the canton of Valais reflect high living costs and social charges: a qualified tradesperson bills between 150 and 350 CHF/m² depending on complexity and materials. Beyond the core cost, factor in any ancillary expenses — removal of existing installations, connections, municipal permits. To finance your works, several options are available: maintenance and repair costs are tax-deductible in the year of completion, and it is sometimes worth spreading major works across two tax years to optimise the deduction. Consult your accountant before planning major works in Sion — Swiss property taxation offers genuine optimisation opportunities.
Regulations and standards — Roofing in the canton of Valais
roofing work in Sion is subject to a precise regulatory framework, and being unaware of it can have real consequences for your insurance coverage and the resale value of your property. The SIA standards (Swiss Society of Engineers and Architects) define best practice for construction and renovation: work carried out outside SIA standards can be rejected at the handover inspection by an expert and may require costly remediation. In the canton of Valais, cantonal energy regulations (based on the MoPEC model) impose minimum insulation values for any replacement of building envelope elements. In Sion, as everywhere in Switzerland, works affecting the structure or the external appearance of a building require a building permit from the municipal technical department — work carried out without one can result in a mandatory reinstatement at the owner's expense.
