Why carry out roofing waterproofing work in the Swiss Romande region
Ensuring the waterproofing of a roof is not just about preventing water leaks. It is also an investment in the longevity of the building and the comfort of its occupants.
Preserve the structure of your home
A poorly waterproofed roof allows moisture to penetrate the load-bearing elements. The materials used for framing and insulation deteriorate quickly, compromising the stability and safety of the structure in the long term.
Improve energy efficiency
Water and humidity degrade thermal insulation, increasing heat loss and energy consumption. A perfectly waterproof roof helps reduce your bills while maintaining optimal thermal comfort.
Enhance your real estate value
A roof in perfect condition and protected against infiltrations enhances the visual appeal of your property. This technical and aesthetic improvement is a strong selling point during a resale or value assessment.
Steps of a roof waterproofing project with Avenir Rénovations Suisse
Each project is conducted methodically to ensure a flawless result.
The different roofing waterproofing techniques in French-speaking Switzerland
Depending on the configuration of your roof, several solutions can be considered to ensure effective protection against leaks.
This process relies on the application of welded or hot-applied bituminous membranes. Durable and proven, this technique is ideal for flat or low-slope roofs, offering durability for several decades.
EPDM is a synthetic rubber membrane particularly resistant to UV and climate variations. Its flexibility and longevity make it a preferred choice for terrace roofs and complex surfaces.
PVC waterproofing is characterized by quick installation and an attractive price-quality ratio. It is suitable for residential and tertiary buildings, offering good mechanical resistance and a wide range of finishes.
This system involves applying a waterproofing resin directly onto the substrate, forming a continuous and seamless membrane. Ideal for treating hard-to-reach areas or those with particular shapes.
How much do roof waterproofing works cost in French-speaking Switzerland
The budget depends on the surface area, the chosen system, the condition of the substrate, and the complexity of the project. Here is an indicative table.
| Type of service | Price per m² (CHF) | Average total price (CHF) |
| Bituminous waterproofing | 90 to 130 | 9,000 to 13,000 |
| EPDM waterproofing | 100 to 150 | 10,000 to 15,000 |
| PVC waterproofing | 80 to 120 | 8,000 to 12,000 |

Regulations for roofing waterproofing work in French-speaking Switzerland
The installation or renovation of roofing waterproofing is subject to specific rules. These aim to ensure the safety of occupants, the quality of work, and the architectural coherence of buildings.
Permits and administrative procedures
In most municipalities in French-speaking Switzerland, work that alters the exterior appearance of the roof requires prior authorization. Even for waterproofing renovations without visible changes, certain regulations require a simplified application to verify compliance with local urban planning and environmental rules.
Technical standards and energy requirements
Interventions must comply with the provisions of the SIA 380/1 standard regarding the energy performance of roofs. A maximum thermal insulation coefficient is imposed to limit heat loss. The use of certified materials is often required to benefit from public aid.
Work in co-ownership or condominium
If your home is in a condominium (PPE), the agreement of the assembly of co-owners is essential before any work. Internal rules may govern the choice of materials, finishes, or even the color of visible elements.
Site safety and compliance
Work at height must meet the safety obligations defined by SUVA. Scaffolding, lifelines, and fall protection devices are implemented to protect workers. The acceptance of the site includes a verification of compliance with all applicable standards.
Take advantage of financial aid for your waterproofing work
Energy renovation and sustainable building protection are encouraged by several aid programs in French-speaking Switzerland. Roofing waterproofing, when it improves thermal performance, may qualify for these supports.
Cantonal and municipal subsidies
The Building Program, established by the Confederation and the cantons, partially funds work to improve insulation and waterproofing of roofs. The amounts vary depending on the treated area, the technique used, and the energy savings achieved.
Energy bonuses from suppliers
Some electricity or gas suppliers offer bonuses to owners who reduce the energy consumption of their property. Waterproofing combined with enhanced insulation may be eligible for this type of incentive.
Reduced VAT rate
Work aimed at improving energy efficiency may benefit from a reduced VAT rate, which lowers the final bill. This measure applies when legal conditions are met and the work is entrusted to a licensed professional.
Conditions for obtaining
To receive these aids, the work must be carried out by a recognized company, and the materials used must meet the performance criteria set by the authorities. Avenir Rénovations Suisse assists you in preparing your file and in finding available funding.
FAQ on Roof Waterproofing in French-speaking Switzerland
When should you redo the waterproofing of your roof?
On average, the waterproofing of a roof lasts between 20 and 30 years depending on the chosen system. If signs of infiltration or detachment appear, it is time to consider renovation.
Can a new waterproofing layer be applied over the old one?
In some cases, an overlay is possible if the substrate is sound and the additional load is supported by the structure. A prior diagnosis is essential to validate this option.
What is the best time to carry out waterproofing work?
Interventions are preferable in spring or summer, when weather conditions are stable. This allows for optimal installation and complete drying of the materials.
Does roof waterproofing require a lot of maintenance?
Annual maintenance is recommended to check the condition of the membrane, joints, and drains. Regular cleaning of leaves and debris extends the lifespan of the system.
Can a flat roof waterproofing be greened?
Yes, some membranes are compatible with extensive or intensive greening. This requires specific design to manage weight, drainage, and membrane protection.
