| Gas | 48 % | 44.4 % |
| Heating oil | 23 % | 20.9 % |
| District heating | 13 % | 9.7 % |

Each line gives the share of buildings using that energy, separately for heating and for hot water. The two columns do not always reach 100%: some buildings combine two systems, or reported none.
A standard non-condensing boiler is usually older and less efficient.
19.1 % of buildings mix housing with shops or offices.
For your renovation projects in Fribourg, the official RegBL figures provide essential context for homeowners. Regarding heritage protection, one building is officially designated as protected out of 2916 structures, highlighting the need to contact the municipality early to secure permits if your property is affected. Please note that data coverage is partial, as the renovation year is unknown for all buildings. Furthermore, information regarding house volume according to the SIA 416 standard is currently unavailable, as all 876 houses fall under other categories. This makes it necessary to perform independent assessments when planning the scale of heating or insulation works.

7 °C. With 3,233 Kj/year of heating needs, the state of your roof directly impacts your energy consumption. A faulty roof can lead to water infiltration or significant heat loss during extreme cold spells.
It is advisable to intervene before structural damage becomes irreversible. Planning should consider the lifespan of materials and signs of wear, such as porous tiles or insufficient insulation.
Anticipating these works allows you to benefit from the best weather conditions to avoid complications related to frost and precipitation, thereby ensuring optimal material installation.
The choice of materials is decisive, especially at altitude where snow loads and frost directly influence the durability of the roof covering.
Homeowners can choose between traditional clay tiles, metal roofs, or more modern solutions, depending on aesthetic and technical requirements. Each material has its own resistance characteristics against local weather conditions.
Furthermore, the decision to integrate solar panels must be made beforehand, as their removal and reinstallation must be budgeted for during roof replacement.
With global irradiation of 1,346 kWh/m²/year, Fribourg offers interesting potential for photovoltaics.
Also consider that roof insulation, carried out simultaneously with the covering, significantly improves energy efficiency and is often eligible for the Building Programme.
In Fribourg, building structures vary and require special attention depending on the age of the building. In older houses, it is common to encounter obsolete or missing insulation.
During renovations, vigilance is required regarding the possible presence of hazardous materials such as asbestos, often hidden in old building elements, especially before 1990. A preliminary diagnosis is necessary to secure the construction site.
Roof networks, including rainwater drainage and ventilation, must also be adapted to current standards. In more recent constructions, the focus is on airtightness and high thermal performance.
It is crucial to adapt your project to the technical specifics of your building to ensure a sustainable renovation that complies with current safety and energy efficiency requirements.
It is imperative to consult the municipal authorities of Fribourg to understand local planning regulations, especially if your building is located in a protected or historic area. Respecting local architectural heritage is an essential requirement.
Municipal regulations define aesthetic and technical criteria for facade and roof works. Never start work without having received the approval of the competent services.
A complete file must be submitted according to local procedures, including plans and precise descriptions. A proactive check with your municipality will allow you to avoid any delays or administrative sanctions during your project.
More information is available via the Building Programme to ensure your project's eligibility.
Regarding taxation, investments in renewable energy, improvement of energy efficiency, and environmental protection are deductible from your income.
If these costs exceed the property's income during the current fiscal year, the surplus can be carried forward to the two following fiscal periods.
In addition, properties older than 10 years can benefit from a flat-rate deduction of 20% on the rental value or choose to deduct actual maintenance costs.
Roof renovation always begins with a phase of technical evaluation and obtaining the necessary authorizations. Once the project is validated and the financial file submitted, choosing the artisans is a key step.
The implementation period should ideally avoid the months of intense winter to limit risks related to frost and bad weather, although professionals are accustomed to the climatic conditions of Fribourg.
Construction generally begins with setting up safety measures and scaffolding. This is followed by the removal of the old covering, possible repair of the framework, installation of insulation, and finally, the installation of the new covering.
Each step requires precise coordination to ensure the building remains watertight throughout the work. Meticulous planning allows for a smooth sequence of tasks between the different trades working on your roof.
Never neglect applying for prior administrative authorizations before signing a contract. Do not forget to include the removal and reinstallation of existing solar panels in your budget if necessary.
Do not choose an artisan without checking their references for similar projects in the region. Ensure that insulation is addressed at the same time as the covering to optimize financial support.
Checklist before your quote requests : Check if your building is listed by the historic monuments service. Precisely identify the desired insulation works. Prepare a roof plan and photos of the damaged areas.
