Roof Renovation Bernese Oberland – Cost, Wooden Balcony & Subsidies 2026

A roof renovation in the Bernese Oberland costs between CHF 250 and CHF 450 per m² of roof area in 2026. Re-roofing alone (tiles or larch shingles) is at the lower end, energy-efficient renovation with insulation at the higher end. Wooden balcony, sheet-metal and possibly solar panel work add to this. This guide covers everything for owners in Thun, Gstaad, Saanen, Schönried, Lenk and around Lake Thun.

Roof types and coverings in the Bernese Oberland

  • Tile roof: standard in lowlands, also Thun and Spiez. Lifespan 60-80 years. CHF 180-280/m².
  • Larch-shingle roof: Saanenland tradition (Gstaad, Schönried, Lenk). Distinct look. Lifespan 80-120 years — larch builds its own protective layer under weather. CHF 250-380/m².
  • Eternit or fibre cement: in some farmhouses and commercial buildings. Asbestos check needed for pre-1990 buildings.
  • Sheet-metal roof: small roofs, carports.
  • Green roof: modern flat-pitch buildings and garages.

In the heritage zone (Saanen and Gstaad village centres), larch-shingle roofing is mandatory — modern coverings are not approved. More: Building permits in Gstaad and Saanen.

Energy-efficient roof renovation with Canton Bern subsidy

An energy-efficient roof renovation includes new insulation (min. 24 cm mineral wool or wood fibre) and a new sub-roof. Benefits:

  • Heating cost reduction: 15-30 % less energy
  • Subsidies from the Bern building programme: typically CHF 40-80/m² insulated area, max ~CHF 30,000 per project
  • Tax-deductible: fully value-preserving, fully deductible
  • GEAK rating: better energy label, higher resale value

We advise on the Bern building-programme subsidy and handle the full application. Typical wait from application to approval: 4-8 weeks.

Wooden balcony renovation – cost and process

The wooden balcony is a central architectural element in the Bernese Oberland (especially Saanenland and Lenk). Renovation costs typically:

  • Oil or stain railing (visible surfaces): from CHF 25-45/m² — every 4-6 years
  • Replace or sand + oil floor: from CHF 80-180/m²
  • Partial structural replacement (rotten beams): from CHF 350-650/linear m
  • Full balcony renovation (small 8 m²): from CHF 12,000-22,000
  • Full balcony renovation (larger 20 m² wraparound): from CHF 28,000-55,000

We recommend inspecting the wooden balcony every 5-8 years and oiling the railing. Greying is avoidable if you don't wait too long. More: Wood care Bernese Oberland.

How long does a roof renovation in the Bernese Oberland take?

  • Sheet-metal repair (gutter, drain): 1-3 days
  • Re-roofing only (200 m² roof): 2-3 weeks
  • Roofing + sub-roof: 3-5 weeks
  • Full energy renovation with insulation: 5-8 weeks
  • Full balcony renovation (20 m² wraparound): 2-3 weeks

We prefer May to October for roof work — snow and frost make it difficult, and natural oils for wooden shingles need temperatures above 8°C to cure.

Permit requirements for roof renovations in the Bernese Oberland

  • Like-for-like (material, shape, colour): no permit, just notification
  • Material change (e.g. tiles → larch shingles): permit required in heritage zone
  • Storey addition or attic conversion: permit required, often architect needed
  • New roof windows (Velux): hard to approve in heritage zone, dormer solution recommended
  • Solar PV: in heritage zone only side roofs, not main roof
