Rate for the installation of a glass roof in French-speaking Switzerland

The selected material plays a role in the appearance, robustness, and maintenance of the installation. In the French-speaking part of Switzerland, frames are generally made of aluminum, of steel, wood, or PVC.

Aluminum is valued for its lightness, weather resistance, and contemporary look. Steel appeals with its strength and marked industrial aesthetic. Wood creates a warm and authentic atmosphere but requires regular maintenance. PVC represents a more financially accessible solution, although less durable.

On average in the French-speaking part of Switzerland, one should budget approximately:

• 1,000 CHF to 1,550 CHF per m² for an aluminum structure
• 1,350 CHF to 2,200 CHF per m² for a steel model
• 800 CHF to 1,300 CHF per m² for a wooden version

The surface area of the glass roof directly influences the cost, as it determines the amount of materials and the duration of the intervention. A standard installation of about 2 m² generally represents a budget between 1,700 CHF and 3,300 CHF including VAT in the French-speaking part of Switzerland. In contrast, a custom or large-scale project can exceed 3,800 CHF, especially in the presence of specific shapes like a rounded, sloped, or domed structure.

The more technical the configuration, the more adjustments and implementation time increase.

The choice of glass impacts clarity, safety, and thermal performance. The most common solutions are:

• single glazing, affordable but not very effective in insulation
• double glazing, providing a good balance between thermal comfort and protection
• laminated glazing, reinforced for better shock resistance

In the French-speaking part of Switzerland, the cost of glazing generally ranges between 110 CHF and 330 CHF per m², depending on the thickness and desired technical characteristics.

To optimize comfort, various features can be integrated: built-in blinds, motorized shutters, LED lighting, automated opening, or home automation control. These features enhance daily use but increase the final amount.

Depending on the selected equipment, an average additional cost of between 650 CHF and 2,800 CHF should be anticipated.

The location of the glass roof also influences the price. An interior installation between two rooms is generally more affordable than an installation on a facade or roof. Outdoor projects often require structural reinforcements and more thorough waterproofing checks.

The presence of load-bearing elements, existing beams, or openings to modify can also complicate the intervention and impact the overall cost.

Labor constitutes a significant part of the total budget. In the French-speaking part of Switzerland, the hourly rate of a qualified professional averages between 70 CHF and 110 CHF excluding tax, depending on the technicality of the project and the necessary adjustments.
