De Dakdokters are experts in green rooftops, rooftop gardens, and sustainable roofing. They see city roofs as the sustainable solution for improving our city lives. Roofs are often abandoned, empty spaces; vast urban areas with the potential to become integral parts of urban life. De Dakdokters transform these areas into places where nature can thrive, food can be grown, and energy can be produced. Their mission is to create more biodiverse cities, provide more space for green recreation, improve rainwater drainage, grow food locally and find new ways to provide clean energy. In in the future, these green doctors hope to transform as many roofs as possible into an urban oasis. Empty roofs are the norm now, but 10 years from now green roofs will have taken over cities all over the world.
