Passive blue roof systems control the rate at which water drains from a rooftop through non mechanical means.
Blue roof drain.
The suitability of a blue roof and potential design options for a given building are determined based on various factors including structural capacity roof type and slope local climate and local regulatory requirements.
For example the ontario building code o reg.
Blue roofs also known as controlled flow roof drain systems are detention stormwater management practices smps that provide temporary storage and slow release of rainwater on a rooftop.

4 6 1 blue roof introduction.
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.
Unlike active systems which inhibit water flow through drainage pipes passive systems temporarily detain water on the surface of the roof by lengthening the path the water must take in order to reach outlet drains.
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.
