Tip: Investing in roof renovation with photovoltaic system
The combination of roof renovation and a photovoltaic system represents a future-proof investment. The renovation protects the building's structure for the long term and increases the property's value. At the same time, the photovoltaic system enables sustainable electricity generation, lowers energy costs, and reduces dependence on rising electricity prices. In addition to attractive subsidy options, owners actively contribute to climate protection and secure stable returns through self-consumption and feed-in tariffs.
Sustainable energy generation
Use free solar energy, become climate-friendly, reduce CO₂ emissions and make a contribution to climate protection.
Independence from energy suppliers
Become independent of energy prices by reorienting your roof. Energy storage can also significantly increase your self-consumption.
Economic advantages of solar energy
Reduce your running electricity costs with a roof renovation, generate income with solar power and increase the value of your property with photovoltaics.
Expert and certified asbestos remediation from the roof
Many roofs in Germany are still covered with asbestos. While the building material is durable, it is demonstrably harmful to health. Therefore, numerous regulations must be followed during its removal and disposal. Our expert staff receive regular training and further education to ensure compliance. At Sonnenexpert, we are qualified and certified to carry out professional asbestos removal from roofs . We will advise you and plan the asbestos removal process for your roof with you.
Why is asbestos remediation important?
Asbestos was commonly used in roofing tiles, facades, and insulation in the past. Today we know: The material is extremely dangerous. Even the smallest asbestos fibers, released during aging or processing, can cause serious lung diseases and cancer when inhaled. Professional asbestos removal ensures safety – for yourself, your family, and your property. That's why expert asbestos removal is essential:
Protect health
No danger from invisible asbestos fibers.
ensure legal certainty
Asbestos has been banned since 1993 and may only be removed by certified specialist companies.
Maintain & increase values
An asbestos-free building is safe, sustainable and retains its market value.
PV system after renovation
Only after the asbestos has been removed are energy-saving upgrades such as a new roof covering or photovoltaic system possible.

Before the roof renovation begins, you will have a personal consultation with our experts and will also receive comprehensive information about energy efficiency options.
