Why a blue roof system isn't a roof

The management of water is a growing concern as the climate emergency and an overworked sewerage system highlight the need for sustainable drainage

A blue roof is a water attenuation system positioned on top of a roof.

Thinking of blue roofs as entirely different from traditional roofs reduces the risks commonly associated with blue roofs from the beginning.

Water should not stay on roofs for longer than is necessary and failure to ensure its ability to be removed quickly will mean falling foul of regulations.

Keeping the two elements (blue roof systems and roofs) separate and distinct from one another means the quick roof drainage required by building regulations can be provided, while water is held for slower, environmentally friendly drainage to meet planning conditions.

Using ACO’s blue roof system allows architects to provide sustainable drainage and building resilience. As it's not a roof, different requirements apply so compliance with known best practice and relevant standards is easier to achieve. Work with one of ACO’s roofing partners to secure a single point warranty on the complete roof build up.

With ACO blue and blue green roofs, water does not remain in contact with the waterproofing layer, dramatically lowering the building risk.

Blue roofs are a more commercially effective alternative to building a large expensive tank that takes up basement space. Installing a blue roof attenuation system on the roof allows that space to be used instead to generate value, for example from secure parking or a gym. It also removes the cost of installing additional pipework to drain water to and from the basement.

Blue roofs can also double as rooftop gardens and hold building services plant and assets, improving the overall resilience and green credentials of the building while making it more pleasant for occupants and building managers.
