Technical guidance for the construction and design of blue roofs has been released by the National Federation of Roofing Contractors.
The information was put together by the NFRC Joint Flat Roofing Technical Committee whose members included membrane and system manufacturers, insulation producers, standards and certification bodies, drainage consultants and representatives from flat roofing trade associations.
Kevin Taylor, head of technical services at the National Federation of Roofing Contractors, said: “No British or European standard covers this type of application so we were tasked with producing these notes to support the design of technically correct Blue Roof construction.
“We hope that this – like Green Roof Code of Practice (GRO) has done for green roofing – will provide comprehensive information and guidance for specifiers, designers and installers of blue roofs.”
The guidance includes sections on drainage, roof deck construction, falls, waterproofing, outlets, overflows, components and finishes.
A Blue Roof is a flat roof designed to allow controlled attenuation of rain fall during heavy and storm events as part of a Sustainable Urban Drainage Systems (SuDS) good practise policy, replicating the natural environment or improving the as built environment.
It treats and releases the water at a managed and controlled rate directly into the sewers waterways and river systems.
Kevin added: “At the NFRC we help our members plan ahead and see both green and blue roof systems as providing sustainable roof drainage solutions for our sector.”
