Balcony doors allow seamless transitions to the outside - the best way to achieve this is barrier-free and with suitable child safety locks.
More quality of life with green roofs
Green roofs are possible on almost any roof - even retrospectively
Green roofs give buildings, garages and carports the opportunity to set creative and ecological accents. Their advantages are as varied as the plants that thrive on them. We show you what is important.

The most important advantages of green roofs
Green roofs - a holistic contribution to the environment
Green roofs are the ideal solution for anyone who wants to transform roof surfaces into natural spaces. Green flat roofs store rainwater and provide a variety of habitats for animals and plants. Another advantage: they compensate for the sealing of property areas and ensure smooth transitions between buildings and open spaces.
More quality of life through green roofs
The benefits of green roofs come into play for every building project and for all types and sizes of flat roofs. Every flat roof, no matter how small, improves the microclimate, reduces the summer heat and filters dust particles from the air. What's more, the mere sight of green spaces has a positive effect on our well-being.
Green roofs help save money
By storing precipitation, green roofs reduce the amount of water that would otherwise end up in the sewage system. This allows rainwater charges to be saved or the necessary soakaways to be smaller. Green roofs also act as a natural filter that protects roof waterproofing from the effects of the weather. The unsealing of existing roof surfaces is often subsidised with public funds.
Green roof types and green roof structures
Extensive green roofs - low roof structure heights
Extensive green roofs have low build-up heights (5-15 cm) and can maintain themselves with minimal maintenance thanks to drought-resistant plants (e.g. herbs, grasses and sedum plants). Extensive green roofs do not require roof irrigation and are also suitable for wooden beam ceilings above carports due to their relatively low weight.
Intensive green roofs - lush gardens
Intensive green roofs require greater substrate heights with which usable green roofs can be realised. Substrate heights of up to 60 cm and more are possible for woody plants or larger roof plantings. In this case, the supporting structure under the green roof must be designed for the high weight not only of the substrate but also of the water absorbed in it.
The roof structure of a green roof in detail
There are no fundamental differences in the roof structure of extensive and intensive green roofs. A root-resistant roof waterproofing, a drainage layer and a filter layer are laid over the roof structure, above which the substrate serves as a planting layer. A gravel strip is usually laid at the edge of the green roof to protect the roof edge.
Green roofs for garages and carports
Green roofs - an insulating layer for garages
Green roofs function like thermal insulation. They protect the garage rooms from heat in summer and ensure that garages cool down less in winter. This effect is particularly important when garages are also used as heated workshops. Green roofs can therefore also save energy costs.
Green carports improve the ecological footprint
Carports with a green roof improve the ecological footprint by providing habitats for animals and plants and helping to improve the microclimate by storing rainwater. If greened carports also have side trellises and wooden wall elements, they also create flowing transitions to the surrounding nature.
Plant diversity on accessible green roofs
Walkable roof surfaces on intensively greened garages offer numerous advantages: they make it easier to water the roof and care for the variety of plants growing there. At the same time, they create retreats that can be used to grow vegetables and herbs. If green roofs are planned to be accessible, the supporting structure of the garage must be designed for the corresponding traffic loads.
Costs of green roofs and funding opportunities
Decisive cost factor: the construction height of a green roof
Depending on the type of green roof, the height of the substrate layer is 5-60 cm. However, it is not just the substrate, plants and other design elements that cause costs. The main cost factor is maintenance - in particular the question of whether the roof planting requires extensive regular watering.
Subsequent greening of garage roofs
The costs for extensive green roofs on garage roofs are manageable and generally limited to the green roof structure. This is because it doesn't matter whether the roof is made of concrete or wooden beams: Subsequent structural measures are usually not required for roofs previously covered with gravel because the weight of gravel and a soaked substrate layer are comparable.
Funding programmes for green roofs
In many cities and municipalities, there are financial subsidies for green roofs in existing buildings as well as for new buildings - information on this can be found on the websites of the municipal administrations and building authorities. Subsidies are also available from the environment ministries of the federal states or from the Federal Subsidy for Efficient Buildings (BEG).
