If you live in a big city or keep yourself apprised of innovative methods of environmental conservation, you’ve probably already heard of green roofs. They’re created using a technique which involves covering a building’s rooftop with all kinds of vegetation: plants, flowers, and vegetables. It’s no secret: green structures provide better insulation and minimize carbon emissions. All in all, they improve air quality while increasing the building's overall energy efficiency.
Following in the same footsteps, lo and behold the blue roof, the new and updated version of the eco-friendly roof system, is intended to solve an increasingly common problem. This innovative system could help cities manage heavy rainfall—yet another way to adapt to climate change.
This new technology came about in Montréal and was developed by Hydrotech—as seen atop McGill University’s Faculty of Education building. The appeal of this design is that it doesn’t interfere with other roofing projects. In addition to solar panels, the roof can accommodate a terrace, vegetable garden, playground, or lounge area, and any type of heating or air conditioning system.
The main purpose of a blue roof is to collect rainfall to reduce any risks of flooding that could be caused by, among other things, a poorly functioning sewage system. Instead, rainwater is stored between aggregates or in a cavity under a paving stone. With a mini-dam-like (or barrier) aspect, a series of valves installed in stormwater drains controls the flow and return of any accumulated water progressively back to the sewer system (the excess will be drained before winter hits).
Pipes can also be included to allow residents and businesses to recover water, for instance, to run cooling towers, washing machines, toilets, clean cars, water plants, and so on.
Typically, these are "smart" roofs. They’re fitted with water-leak detectors and sensors that measure water levels and transmit energy conservation data and weather conditions. These devices are convenient when it comes to performance improvement, damage prevention, and remote monitoring, as well as early water release in the event of a storm.
The only minor drawbacks:

Environmental standards, specific requirements, precise calculations... Such a project requires a unique blend of municipal representatives, clients, engineers, and builders. Any company installing the blue roof will also be responsible for future maintenance and repairs.
This project begins with a feasibility study: if a blue roof is to be installed on an existing building, the structure must be able to support it. A concrete structure is usually recommended, rather than steel or wood. Then, the existing waterproofing membrane is inspected and may have to be replaced with a new, more modern one, made of bitumen and recycled materials such as tires and glass powder.
The water storage area may or may not cover the entire roof, depending on what’s already there. This eco-friendly roof is only installed on a flat roof or one with very little slope. Nevertheless, when it concerns a gable roof, it’s possible to install a similar system: rainwater harvesting tanks.
The rooftop terrace is still the easiest way to implement a blue roof. The space between the pavers and the roof can be used to hold large amounts of water. However, heavier and thicker pavers are required. Also, the paver pedestals are usually customizable, enhancing their practicality.
Blue and green roofs are two ecological systems that can be used in conjunction to maximize the use and management of water storage. Considering it as the logical continuation of the green roof, the vegetated basins will take whatever is necessary for their survival and will be fitted with storage tanks to hold rainwater temporarily.
