A blue roof is not rainwater storage on a roof.
Blue roof drainage.
The patented blue roof system utilises the roof construction for the attenuation of stormwater releasing it at a controlled rate in the period following the storm.
Instead of forcing rainwater to flow directly into an underground drainage system surface water is collected and stored and if necessary cleaned before it is used or released back into.
Cavidrain building abg cavidrain drainage geocomposite is a preformed cavity drainage system designed to relieve water penetration from basements and buried structures.
Blue roofs require regular maintenance and inspection of the outlets to ensure the drainage holes are free of debris or blockages.
Passive designs use hydraulic structures such as weirs orifice plates or hydraulic regulators to control release rates from the roof.

The bauderblue roof system is a sustainable drainage method designed to attenuate and manage stormwater on a flat roof over a 24 hour period via a restrictive flow outlet.
Roof level sustainable drainage system.
Blue roofs are constructed on flat or low sloped roofs in urban communities where flooding is a risk due to a lack of permeable surfaces for water to infiltrate or seep back into the ground.
It mimics the natural environment by managing the discharge of rainwater from roofs at a controlled rate in line with a drainage strategy and overall site flood risk assessment.
Blue roofs that are used for temporary rooftop storage can be classified as active or passive depending on the types of control devices used to regulate drainage of water from the roof.
Harmer bluroof drainage outlet.
A blue roof provides source control managing rainfall where it falls by temporarily attenuating it on a roof.
A bauderblue roof is designed specifically for each individual project.
Blue roof drainage system suppliers should talk you through the process explaining what each layer does and why it is so effective.
Inspections should take place following any significant storm event any notable traffic or remedial works that take place on or around the roof and following leaf fall during the autumn months to ensure leaf.
