World Green Roof Day 2025

World Green Roof Day is an annual celebration of the architectural design, technology and innovation that enables us to combine engineering and ecology to create habitat and grow plants on top of man-made structures.
World Green Roof Day falls on 6th June 2025 and promises to be a real treat for anyone interested in sustainable buildings, biodiversity net gain and the fight against climate change.
GRO are proud to play an integral part in the World Green Roof Day celebrations and would like to encourage all of our friends and followers (members and non-members) to participate in any way that they can.
We’re celebrating the many benefits associated with green roofs as well as the developers, architects, planners, suppliers, installers and maintenance crews who continue to help grow this global industry.

Green Roof Benefits
- Absorption of excess rainfall thus reducing the risk of flooding
- Creating wildlife habitat
- Contributing to biodiversity net gain without disrupting human activity at ground level
- Combatting the urban heat island effect. Plants cool the air through evapotranspiration and can make city temperatures feel a lot more comfortable. Plus a living green roof changes the albedo of a building – which ensures that energy from the sun is absorbed rather than reflected.
- Thermal performance – The evaporative cooling effect of green roofs, combined with the increased thermal mass of the build-up, can reduce the need for summer cooling through the use of air conditioning, with a resultant reduction in carbon emissions.
- Rooftop gardens can be used for leisure and to promote wellbeing in areas where access to green space is limited
- Pollution control – By filtering dust from the air, green roof plants help to keep our atmosphere clean and breathable.
- Absorbs CO2 from the air and provides oxygen thus improving air quality
- Offering the potential for rooftop farming to support sustainable food supplies
- Increasing efficiency of PV panels on a green roof compared to a plant-free roof
- Aesthetically beautiful
