Blue Roof Vs Green Roof

Waterproofing the specification and detailing of which is integral to the success of a blue roof system protecting the building against water ingress.

Blue roof vs green roof.

Green roof surfaces filter out pollutants before they can reach at risk water sources beyond the home. Green and blue the optimum solution. Whilst the water management engineer will be focused on how much water is stored and released a blue green roof provides wider benefits. Of course a blue roof on its own is positive yet it provides only one solution.

Green and blue roofs are both excellent choices when it comes to environmental sustainability. This answer received the most positive responses. And that brings us to the blue roof. Creating blue green roofs you can access or gaze upon increases the real estate value of the space.

Abg blueroof offers a new development in the management of storm water by collecting and retaining rain fall within the actual roof structure before discharging at a defined controlled rate. So unlike a blue roof the water will not be slowly released from a green roof but less water will end up in sewers and drains until the soil is saturated. Blue roofs may not be covered in moss but they do share the same goal of mitigating storm water runoff. This therefore suggests that the voters recognise the potential of both systems to help with water management at roof level.

Also depending on project size the payback for the investment in these systems may be more or less immediate. Whilst green roofs featured slightly higher than blue roofs in the voting it is positive that the idea of both blue and green roofs is accepted by most of the voters. Both are good for the environment a blue roof can be beneficial to the local environment by reducing the risk and the amount of flooding.

They do it by allowing water to pool or pond on roofs storing the runoff in a separate area. Blue roofs can include open water surfaces but can also be used in buried applications such as raised deck surfaces or green roofs.

Today blue roofs are significantly less expensive than green roofs often costing under 1 per square foot whereas the average green roof in the us is estimated to cost 15 20 per square foot. However they each have a separate set of goals. A blue green roof a wider range of benefits. Blue green roofs help to cool the environment increase roofing materials lifespan and at the same time reduce the heat influx in to the building reducing air conditioning demand.
