Vegetative roofs, also known as green roofs, are thin layers of living vegetation that represent the possibility of creating a natural element even in urban structures, which can be an effective tool for a sustainable urban ecosystem. Their design therefore requires a special attention. The aim of this paper is to present the importance of green roofs in the local, but also in a broader understanding. Their valuable asset and benefits are directly related to the green infrastructure, which is more specified in this work. The research itself deals with the suitability of flowering herbaceous plants for extensive vegetative roofs. The study also focuses on the interpretation of the results from measurements of specific perennials as representatives of different perspectives on the overall quality of extensive green roofs. The next phase of the research focuses on a group of stonecrops which, thanks to their metabolic abilities, stimulated the establishment of an experimental roof garden. The planting of Sedum acre, Sedum album, Sedum sexangulare, Sedum spurium and Sempervivum tectorum species was realized in Fiľakovo (Central Slovakia). All layers that need to be made during the implementation of the vegetative roof are defined, as well as a description of the implementation of segmental planting of stonecrops. The last part of the experimental part of the paper is the general procedure of implementation and maintenance of green roofs. The results reveal how it is possible to efficiently and easily create a functional element of the green infrastructure at the regional level and in urban landscapes.
