Renovations, heritage and volumes
For your renovation plans in Grabs, please note that the federal building register data is currently partial. With a median house volume of 776 m3 calculated from a sample of 30 buildings based on the SIA 416 standard, these figures provide a baseline for estimating the scale of your heating or insulation upgrades. As the register covers 2120 buildings, please be aware that information regarding renovation years is unavailable and no properties are recorded as protected heritage sites. Consequently, you should rely on professional on-site assessments for these specific aspects while using the volume data as a reference.

The importance of thermal insulation
During a roof renovation, it is crucial to think about insulation. Insulating the roof at the same time as the covering is a recommended strategy, as it is often eligible for the Buildings Programme at federal and cantonal levels.
A well-insulated roof significantly reduces your heating needs and increases indoor comfort throughout the year. Remember to check the current standards in the canton of St.
Gallen to maximize the energy performance of your home after the renovation work is completed.
Handling solar installations
If your roof is already equipped with solar panels, their removal and refitting must be budgeted for. These operations require the intervention of qualified professionals to avoid damaging the equipment or electrical connections.
Careful planning helps to avoid unpleasant financial surprises. Make sure to include these specific costs in your overall renovation estimate.
By using the RenoIndex simulator, you can get a clear overview of the costs associated with this type of complex intervention in your local area of Grabs.
Adapting to climatic conditions
Since Grabs is located in a geographical area where altitude plays a role, snow loads and frost directly influence the choice of roofing materials.
It is essential to select robust materials adapted to local climatic conditions to ensure the longevity of your roof. Working with local craftsmen who are familiar with the specificities of the canton of St. Gallen is a major asset.
They will be able to advise you on the most resistant technical solutions to cope with regular seasonal weather.
Planning and overall budget
A roof renovation requires rigour. Beyond the choice of tiles or insulation, one must anticipate the costs of logistics and safety on the construction site.
