Specifying Green Roofs with the NBS and GRO
The collaboration will help specifiers access the most accurate specification guidance to secure the multitude of environmental and health benefits that Green Roofs provide.
Over the past 20 years, green roofing has been establishing a foothold within the UK built environment. It is now considered an established building practice, particularly as climate change mitigation measures are sought. Green roofs offer a nature-based route to enable passive cooling and floodwater management services, while also providing support for wildlife to help reverse biodiversity decline.
A key remit of GRO is ensuring that the expert knowledge its members have gained is shared with designers. Through this collaboration GRO’s wealth of expertise covering different systems including, biosolar roofs (solar panels and green roofs combined), and blue roofs (with additional surface water management features) will now be shared with NBS users, enabling them to benefit from this too.

The NBS supporting sustainable specification
Commenting on the partnership, Sascia Elliott, Head of Partnerships at NBS, said: “Architects and landscape designers have been key in the transition of green roofing from niche to mainstream. Yet due to the rapidly evolving nature of the solutions available, it was crucial that we had access to experts in the field, who have real world knowledge of the realities of specifying, installing and maintaining these green roofs, along with the latest guidance around biosolar and blue roofs. Working with GRO will ensure that specifiers can be confident they’ve access to the latest and most trusted guidance.”
Mark Harris, Chair of GRO, said on the partnership, “NBS provides key resources for the design and specification of buildings in the UK, including the specification of roofing systems. Our collaboration with NBS, has provided the opportunity to demonstrate our extensive knowledge and help to educate construction professionals. The organisation supports them in the specification of high quality green, blue and biosolar roofs that positively contribute to climate change adaptation and mitigation.”
The act of incorporating plants into the building envelope involves collaboration and skill-sharing across many professional disciplines, and GRO has developed and continued to update its Green Roof Code of Best Practice. The organisation has also created a professional installers qualification (L2 and L3) with Lantra, which has been available since 2019
As board members of GRO we are delighted with this news.
The GRO Code of Best Practice is an essential tool in ensuring optimum green roof installations with a range of excellent green roofing systems for every project. Following this guidance allows for the benefits of green roofs to be fully realised.
