Green roofs are adaptation measures to mitigate the effects of climate change in urban areas. Green roofs and other adaptation measures are hardly implemented or being led by local governments and public authorities with a modest role of private actors (Mees, 2014; Stamatelos, 2012). The involvement of private actors is beneficial to share risk, bring resources and skills to the green roof adoption process (Harman, Taylor, & Lane, 2015). A strong involvement of private actors and the establishment of hybrid governance arrangements would contribute to expand the implementation of climate adaptation measures, but there are barriers that impede this involvement to happen (Mees, 2014; Biesbroek, 2014). The following research aims to obtain a deeper understanding of those barriers. Among all private actors, this research focuses on private roof owners since those are directly responsible for implementing green roofs on their rooftops. This research focuses on private roof owners from urban areas in the Netherlands. This research explores the barriers that roof owners experience in the process of implementing green roofs. The information of the present research is based upon interviews. This research aims to achieve a better understanding of the barriers that affect private actors who own properties with roofs. Firstly, these barriers are identified and their relevance is calculated. Secondly, the underlying causes of these barriers are analysed. Thirdly, the acceptance of potential policy tools to overcome such barriers are analysed. With this understanding, the final goal of this research is to draw advice about how to design strategies to overcome barriers to climate change adaptation. The final output of this research is a set of recommendations on how to effectively involve private actors in the adoption of green roofs in urban areas. The scientific relevance of this research is to gain insight of the causality of the barriers to climate change adaptation. This advice is societally relevant because it can help policymakers to draw policies towards a more effective implementation of green roofs and contribute to adapt the city to the unavoidable consequences of climate change. The results of this research are that the main barriers to green roof adoption are the competition between climate change adaptation and mitigation measures, the perception the costs of green roofs are higher than its benefits, the lack of resources and the problem alienation. These barriers should be overcome by policies that target their causes and are perceived as acceptable by roof owners.
