NFRC unveils updated GRO Code for green roofing

NFRC unveils updated GRO Code for green roofing

2 November 2014 Email this article

Supported by The National Federation of Roofing Contractors (NFRC) - the UK’s largest roofing trade association – the Green Roof Organisation (GRO) has unveiled a new and updated GRO Code for green roofing. The revised code is designed to provide assistance for anyone who is involved in the design, specification, installation or maintenance of green roofing.

First published in 2011, the GRO Code is intended to be a code of best practice and to serve as a guide for behaviour and standards relating to all matters in green roofing. This latest update contains more detailed information on meeting the requirements of the London Plan Policy, together with added guidance on substrate installation and waterproofing.

Commenting on the latest GRO Code, Simon Poe, Business Operations Director at Alumasc Roofing and a member of the GRO Advisory Technical Group 2013 said: “Research has indicated that green roofs respond differently to the environment in which they are installed. UK green roofs will therefore perform best if they are tailored to the environment in the UK.

The publication of the inaugural GRO Code in 2011 was a positive first step in the pursuit of good practice in the design, supply, installation and maintenance of UK green roofs.”

Simon adds: “The new edition of the Code demonstrates the industry's desire to further enhance the quality of green roofs in the UK. The Code informs the decisions of professionals that specify, manufacture, install or maintain green roofs through broader and more detailed guidance. In future, the Code will underpin further enhancements; leading towards an ultimate ambition of prescribing acceptable ranges of performance for components on a quantitative basis.”

Ray Horwood CBE, Chief Executive of NFRC concludes: “Green roofs perform a vital role in helping cities adapt to the effects of climate change. However, green roofs can only provide these environmental benefits if designed and installed in a way that ensures that minimum performance criteria are met. This code therefore highlights the important green roof design, installation and maintenance considerations and provides guidelines as to how they can be accommodated in the final green roof scheme.”
