Abstract: The aim of the research was to valorise the analysed urbanized area in the direction of determining the hierarchy in the order of interventions aimed at increasing the share of biologically active area and natural field retention, the potential impact of green roofs on the valorisation of the studied urbanized areas. The research covered the Gajowice estate in Wrocław. The scope of the research included the division of the area into working cells, for which valorisation was carried out using the point method based on the criterion of the degree of covering the land with vegetation and the degree of covering the area with various types of buildings. The valorisation result was determined on the basis of a comparative matrix taking into account the results of the partial assessment of vegetation and building cover. The impact of green infrastructure (green roofs) on valorisation was simulated by proposing their location on buildings with the so-called big plate. The introduction of green roofs on selected buildings improved the valorisation result in some research cells, reducing the number of cells requiring intervention. This raised the valorisation assessment by even two classes, which resulted in a significant reduction in the number of critical areas, with too much hardened surface, and increased the number of areas with a satisfactory level of biologically active surfaces.
