With the increasing concern about the impact our development of the planet is having on the worldwide environment and the UK government calling for sustainable development, green roofs offer a number of benefits over more traditional forms of roofing, helping to meet sustainable development objectives:
Flooding floored
Following a heavy rainfall a green roof will initially retain more rain than a conventional roof. This minimises the initial heavy run-off, which can cause localised flooding and put pressure on the sewage system. The remaining water then drains off more slowly, allowing more rain to remain in the natural water cycle and less in the sewage system.
Ssh …
The soft layer of sedum blanket growing on a green will absorb sound, as opposed to hard conventional roofs which can reflect noise. The same layer improves the buildings sound insulation properties, reducing sound pollution within the building.
Thermal Insulation
The addition of a green roof layer to a property increases its thermal insulation properties, making it warmer in winter, cooler in summer and reducing those all important (and rising!) energy costs.
Home sweet home
Green roofs can help compensate for the loss of green surfaces, sacrificed to building developments. This helps to provide an environment for the development of wildlife, especially bird, plant and insect life, increasing the biodiversity in our towns and cities.
