This distribution describes recorded buildings, not your system's consumption or efficiency.
| Energy | Heating | Hot water |
|---|---|---|
| Gas | 29 % | 27.2 % |
| Heating oil | 40 % | 25.4 % |
| District heating | 7 % | 5.9 % |

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.
23.8 % of buildings mix housing with shops or offices.
For your renovation plans in Rorschach, the official register indicates that 23 of the 1065 buildings are under heritage protection, necessitating early consultation with municipal authorities regarding permit requirements. Regarding building volume, data coverage is partial as there are no recorded SIA 416 standard measurements for the 280 houses identified, which complicates the estimation of heating or insulation project scales. Since there is no median renovation year provided, you lack historical context on recent updates. Homeowners should conduct a thorough site assessment to determine the true condition of their property and plan necessary renovations based on specific structural needs.

Taking advantage of the replacement of your roof covering to insulate your roof is a wise approach. Thermal insulation significantly reduces your heating bills. In the canton of St.
Gallen, as elsewhere in Switzerland, it is important to note that insulating the roof together with the covering is often eligible for the Buildings Programme. Such an improvement also increases the resale value of your property.
Ensure you comply with current thermal standards to maximize the comfort of your interior throughout the seasons, both in summer and winter.
If your home is already equipped with solar panels, their presence slightly complicates the renovation project.
It is imperative to budget for the removal and refitting of these installations by qualified professionals to avoid any damage to the photovoltaic cells. This cost must be integrated into your overall renovation budget from the start.
A renovated roof is also an excellent opportunity to optimize the orientation or power of your solar system to maximize your energy autonomy and make the most of your investment.
Rorschach enjoys a specific geographical location. However, if your project is located at altitude, climatic constraints become stricter. Snow loads and frost significantly influence the choice of covering and structural materials.
It is crucial to opt for resistant materials adapted to local winter conditions to ensure the durability of your roof.
Consult a specialist to choose tiles or sealing systems capable of withstanding freeze-thaw cycles and the increased weight of accumulated snow.
A successful roof renovation requires rigorous planning. Start by assessing the current state of your roof structure and covering. Once needs are identified, it is advisable to request several comparative quotes from local companies.
To avoid unpleasant surprises, use our free RenoIndex estimator. This tool offers you an estimated price range in Swiss francs based on market standards.
Good preparation, including budget, timeline, and material choice, is the key to successfully carrying out your work with peace of mind.
