GREEN & BLUE INFRASTRUCTURE
INTRODUCTION TO BLUE ROOF STORM WATER ATTENUATION SYSTEMS
Blue roof systems offer a sustainable alternative for minimising surface water run-off , providing source control as part of the Sustainable Drainage System ( SuDS ) requirement on modern developments . Blue roofs are rated as the most sustainable technique in the CIRIA SuDS manual guidance based on their contribution to reducing the risk of flooding and pollution and their positive impact on the local landscape & wildlife ecosystems when combined with a green roof finish . With land at a premium , blue roofs allow the developer to maximise usage of any site , especially in city centre developments where underground storage systems are impractical and expensive to excavate .
Installation and Maintenance
Blue roof systems should be installed by an experienced and specialist contractor with supervision from the manufacturer , with provision for post installation quality checks and annual maintenance . Recent examples of blue roof installations include prestigious projects such as the Post Building , Royal College of Art and Rathbone Market in London , Middlewood Locks apartments in Manchester and the new Edinburgh St James retail development .

Environmental benefits
When combined with a green roof surface finish , blue roofs make an important environmental contribution including helping to absorb CO2 from the atmosphere and reducing the urban heat island effect , absorbing low frequency sounds and promoting new wildlife ecosystems and biodiversity .
