In view of climate change, green roofs are becoming increasingly important. But which type of green roof is suitable for your roof? We explain the differences between extensive and intensive green roofs and help you make the right decision. Green roofs are more than just an aesthetic trend. It offers numerous ecological benefits and can even help to improve the urban climate. There are two types of green roofs: extensive and intensive. Both variants have specific properties and areas of application.
Extensive green roofs: low-maintenance and resource-saving
Extensive green roofs are characterized by extensive but restrained planting. With a maximum build-up height of 15 cm, it is particularly suitable for roofs that cannot bear a high load. The plants used are generally undemanding and low-maintenance, such as mosses, herbs and grasses. A major advantage of extensive green roofs is that in most cases they get by with natural rainfall and do not require additional irrigation.
Intensive green roofs: the garden above the clouds
This contrasts with intensive green roofs, which are more like a roof garden and allow for a more varied design and even accessibility. With a construction height of over 25 cm, it offers space for more demanding plants, paths and terraces. Intensive green roofs can therefore create a valuable habitat for people and animals in urban areas. However, this type of green roof requires a higher load-bearing capacity of the roof, regular maintenance and often additional irrigation. Between these two main forms, there is also the transitional area of simple intensive greening. With a construction height of 15 to 25 cm, it offers more design options than the extensive variants.
Decision-making factors for your green roof
Various factors need to be taken into account when choosing a suitable green roof. In addition to the load-bearing capacity of the roof, the desired maintenance requirements, the intended use and the budget must also be taken into account. Extensive green roofs are often cheaper to install and maintain, while intensive green roofs offer more opportunities for active use of the roof area. Regardless of the type of green roof you choose, you will benefit from numerous advantages. These include improved thermal insulation, protection of the roof cladding from UV radiation and extreme temperature fluctuations as well as rainwater retention. Green roofs also help to improve the microclimate and can serve as valuable green spaces in urban areas.
