Extensive Green Roofs – An Ecological Alternative to Conventional Surface Protection

Extensive landscaped roofs are an ecological alternative to conventional surface protection or ballast layers such as gravel and pavers. They are lightweight and have a shallow build-up height. Suitable plants include various Sedum species, herbs and some grasses. After establishment of the vegetation, the maintenance is limited to one or two inspections a year.

If designed specifically to increase the biodiversity and attract a particular fauna and flora, they are called “Biodiverse Green Roofs”. Biodiverse green roofs reproduce natural habitats and attract flora and fauna into the area, e.g. by providing food, nesting opportunities or resting places for creatures, such as spiders, beetles, butterflies, birds, etc.

Green roof with solar system and bee hive

Bee Pasture

The System Build-up ”Bee Pasture“ is an extensive green roof and one module of a “Biodiverse Green Roof” with a special focus on a long-lasting supply of  nectar and pollen. The vegetation layer can be realised with plug plants according to the  ZinCo plant list “Bee Pasture” and can also be established on partial roof areas. In dry periods, an additional irrigation is necessary to maintain the nectar and pollen production of the plants.
