Abstract
The research object is the installation process of modular green roofs with planters placed on the concrete roof’s surface. These roofs effectively reduce rainfall disposal, prolong the lifespan of the roof coating, and enhance urban aesthetic and recreational spaces. Green roofs reduce houses’ gas emissions and increase green spaces in densely built areas. The spatial–technological model was developed for the proposed modular green roof based on network planning, scheduling theory, and graph theory. The sequence and composition of technological processes and operations were established for the installation process. The functional model of installing a modular green roof has been developed. The model makes it possible to optimise the principles of saving labour contribution (working hours) and time.

Summary
Green roofs on buildings have multi-disciplinary benefits such as the improvement of rainfall disposal, the prolonged lifespan of the roof coating, the enhancement of urban aesthetic, and the creation of recreational spaces [1,2]. A quantitative analysis of 1623 English language sources indexed in Scopus from 1981 to 2020 shows that research on green roofs has steadily increased. Green roofs showed a surface temperature cooling effect [4,5]. Sustainability concerns have necessitated a shift towards sustainable urban water management systems, which could be analysed as multiphysics systems [12]. These systems include wet ponds, rain gardens, and green roofs [13]. Green roofs can contribute certain pollutants to rainfall disposal [14]
