The proliferation of vegetated, or green roofs, warrant a revisit of the terminology used in order to efficiently, and without confusion, convey information among scientists, policy makers and practitioners. A Web of Science and Google Scholar search (from 1996 to 2018) showed a steady increase in green roof articles, reaching close to 300 per year in WOS and ca. 2500 in Google Scholar, with approximately 10–20%, and up to 40 % of all articles using the terms extensive and/or intensive, especially in recent years.

Within the context of enhancing sustainable and livable urban environments, one aim is to establish multifunctional green infrastructure (GI). We argue that in order to successfully plan and manage the development of GI, an inclusive and future-oriented stance concerning the needs and expectations of urbanites is required. By using green roofs as an example, the aim of this paper was to offer insights into how people envisage novel GI in urban environments and to reveal the scope of meanings and values people attach to these kinds of green infrastructure.

Growing and densifying cities set challenges for preserving and enhancing sufficient and good quality green urban environment. Rooftops offer vacant room for additional urban greening that may contribute to the well-being of people and the liveability of cities, but this potential lacks empirical support. In spite of the fact that even small green spaces produce, for example restorative experiences, the literature concerning the experiential and recreational benefits of green roofs is still scarce.
