Roof Day
2025
Celebrating
Starting in 2020, World Green Roof Day (#WGRD) has been
creating connections around the globe to embrace, enjoy
and showcase vegetated rooftops.
Since this time, there have been changes in green roof
design, concepts and builds to become more
multifunctional, including solar panels or areas
designated for people and for nature.
The theme for World Green Roof Day 2025 is Education.

About World Green Roof Day
Raise the roofs
This year’s theme for World Green Roof Day will
focus on education.
Let’s value the many ways we can educate, from practical
training and experiential learning, which will create the
next generation of green roofers to academic research
projects that will produce valuable data to support the
green roof industry.
