Living roof benefits
Extending Wildlife Habitats Living roofs are particularly beneficial to insects and bird life, providing more green space and feeding spaces for them. Research in Switzerland and the UK has demonstrated that living roofs can provide important refuges for rare invertebrate populations.
Increasing Urban Greenspace
The urban environment can be very grey and lifeless, especially when seen from above. Living roofs introduce colour and life to the urban environment and improve the overall urban scene, improving the quality of life for those in the vicinity.
Improved Air Quality
By absorbing pollutants from cars and factories, pollen, and dust, the air quality of urban spaces in particular is improved by living roofs.
Reducing the Urban Heat Island Effect
By insulating buildings, cooling roof surfaces and providing plants and a permeable substrate for water to be stored in and to evaporate from, living roofs help to combat the problem of overheating cities during the summer.
Storm water Management
One of the causes of the flooding, particularly in recent years, is that when large amounts of rain falls it all runs quickly into storm drains or rivers which then cannot cope. Living roofs soak up huge amounts of water which is then released more slowly into the drainage system or is evaporated back into the atmosphere. This will become increasingly important as a consequence of climate change. Living roofs also improve the quality of water and although the amount of water is reduced it is possible to rainfall harvest from roofs that have been greened.
