Advantages of Green Roofs

Increase in lifespan of roof surfaces

Ultra-violet rays of sun constantly attack roof surfaces resulting in huge thermal fluctuation. This reduces its lifespan. Eco-friendly surfaces increase the lifespan of waterproofing membranes lying underneath them by creating a barrier, which protect the membranes from the ultra-violet rays and daily temperature fluctuations. The membranes of these surfaces last twice more than membranes on traditional surfaces.

Improves air and water quality

It’s a well-known fact that plants produce oxygen and reduce carbon dioxide. Eco-friendly surfaces drastically reduce the heat island effect. Plants on building tops remove airborne particles and volatile organic compounds, which in turn improves quality of air. Eco-friendly surfaces absorb the harmful particles and prevent them from entering the water system, thereby improving water quality.

Improves microclimate & provides rainwater management

Vegetation of building tops cools the surrounding air thus improving the microclimate within their area. Depending on their design, they also curtail immediate water run-off by nearly 50% thereby enabling rainwater management.

Saves other valuable resources & improves energy performance

Environment-friendly building tops extensively use recycled products, which saves other valuable resources. Most traditional roofs don’t use recyclable products, which lead to wastage of other resources. Since eco-friendly surfaces buffer temperature extremes, it improves the energy performance of the building.
