The Green Roof Organisation (GRO) has published its Green Roof Fire Performance Best Practice Guidance, setting a new benchmark for fire safety compliance across the industry.

Developed in collaboration with members of the BSI fire committee and in consultation with the Building Safety Regulator, this best practice document is designed to remove confusion and clarify exactly what’s required to meet the fire safety requirements of Building Regulations across the UK.

It builds on and updates the 2013 DCLG ‘Fire Performance of Green Roofs and Walls’ publication, offering updated, clearer and more practical guidance for green roof specification, design and installation.

Highlights include:

– Clarification on the use and dimensions of gravel margins as fire, wind and vegetation breaks
– Clear guidance for BROOF(t4) compliance without testing (e.g. 80mm growing medium with <50% organic matter)
– Clarification of the guidance within DCLG ‘Fire Performance of Green Roofs and Walls’

This document has been widely welcomed across the industry and reflects GRO’s commitment to safety, clarity, and best practice.

Next steps:

GRO is now progressing plans for a dedicated Fire Compliance Assessment Programme to give its members and the wider industry greater clarity on achieving fire-compliant green roofs.
