The GRO Green Roof Code—Anniversary edition 2021 incorporating June 2023 amendments

This guidance aims to try to reverse the decline in the bird population in the UK by raising awareness amongst the roofing industry and encouraging the installation of nest boxes.

This guidance is in respect of fire risk and the spread of fire . GRO has consulted the Building Regulations Approved Document B “Fire Safety” and the additional guidance as laid out in the Department for Communities and Local Government document “Fire Performance of Green Roof and Walls” (August 2013).
