In an exemplary embodiment, a system for releasing stormwater on a rooftop of a building structure includes at least one drain water retention device including a float control device to measure volumetric stormwater retained in the rooftop and a valve to operatively open a drain when the measured volumetric stormwater is exceeded, at least one leak detection device configured to detect a water leak, located under an underlying surface of the rooftop, the at least one leak detection device detects the leak in response to change in relative humidity levels or dew point under the underlying surface of the rooftop, and a controller, executing control instructions, in communication with the at least one drain water retention device for selectively controlling the valve in accordance with the control instructions, the controller includes a storage associated with the controller for storing the control instructions. The control instructions are performed according to the steps of measuring the volumetric stormwater retained in the rooftop, determining a duration of time of stormwater retained in the rooftop, determining a location of the building structure to provide prior estimated precipitation and atmospheric conditions, defining a predefined allowable tolerance, and comparing the measured volumetric stormwater with the predefined allowable tolerance and, if the measured volumetric stormwater exceeds the predefined allowable tolerance, opening the drain to remove the stormwater.
