Blue Roofs

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. A Blue Roof will treat and release the water at a managed and controlled rate directly into the sewers waterways and river systems.


What is its Purpose and Who is it for?

Fundamental to this guidance is the principal that a Blue Roof should not be considered as a water storage solution.

No British or European standard covers this type of application at this moment in time. Which is why a committee formed of the NFRC Joint Flat Roofing Technical Committee, whose members include, Membrane and System Manufacturers, Insulation Producers, Standards and Certification Bodies, Drainage Consultants and representatives from Flat Roofing trade associations, was tasked to produce the guidance to support the design of technically correct Blue Roof construction and provide information for specifiers, designers and installers.
