Green roofs are increasingly popular as a mitigation action against the reduction of green areas in Slovak cities. Therefore, it is essential to analyse and compare building materials circularity and environmental impact indicators during the whole life cycle of the roof assemblies. This study considers four design alternatives for green roofs. One Click LCA software was used to model the green roof design alternatives and determine the building circularity indicator which was used to represent the total materials circularity both in the use of materials for the project as well as end-of-life handling. This analysis can help identify areas where improvements can be made to improve the building circularity score of the green roofs. When assessing circularity, it is the mass proportion of materials that are either recycled or used as material, with 50% of materials either being recycled (with a loss of value, such as re-using concrete as aggregate) or used as energy (such as wood) or incineration of plastic products. The circularity of the compositions of the evaluated green roof structures is quantified as 18%, 15%, 14%, 17%, 57% and 71%. Compositions using wood and wood-based materials have a much higher circularity than concrete, steel and waterproofing.
