A green roof is also referred to as living roof and is a foremost feature in an eco-friendly or green home. However, it may also be referred to roofs that implement some format of green energy like roof with solar panels. In laymen terms, it is for roofs that are fully or partially covered with plants and serves as a green blanket at the top of the house. It is also designed for aesthetic purposes. With exponential and luxury living being the demands of modern times, green roofs are a small effort to check our carbon footprints on mother earth. Green roofs have been in existence since the time of Mesopotamian civilization and have been extensively used around the world to protect homes and structures from extreme weather effects.
Benefits of Green Roofs
Increased vegetation leads to
Green roofs can be “extensive” or “intensive” depending on the kind of plants that are planted. In extensive format, the plants are for aesthetic usage and generally low growing plants are used. In intensive green roofs, larger plants and trees are planted. These require better drainage and water proofing systems as well as frequent maintenance. Since there is additional load on the structure, the load bearing capacity of the structure should be designed accordingly.
There are however a few disadvantages of a green roof which can be mitigated through intelligent planning and using appropriate material.
Drawbacks of Green Roofs
For the load bearing structure, large structure such as monolithic reinforced concrete, precast concrete panels or slabs with hollow terracotta pots are most suitable. With proper designing and home plan, prefabricated concrete slabs can be used due to their specific size. Also, prefab elements should be used to contain side-pressure of the higher soil layer. With proper maintenance, sustainable green roofs can make for a healthier, greener and better living experience.
