Today in the blog we tell you the main benefits of green roofing in buildings. Social, environmental and economic benefits.

The green roofs retain and purify rainwater.

First of all, the main benefit that we want to highlight on the green cover is that rainwater or what is the same lrainwater are absorbed by the vegetation of the roof and are returned to the atmosphere by the evapotranspiration effect. This reduces the water load of sewer systems by 70 to 95%.

In regarding the purification of stormwater, green roofs prevent all those pollutants that pass from the atmosphere and perch on the vegetation, reach the streams and water channels and thus improve water quality.

Green covers improve habitat.

Green roofs can be used to allow different species of insects to inhabit them and thus restore the ecological cycle that is currently altered by urban infrastructure.

In Central Europe green roofs were installed in 1970 with the aim of conserving and ensuring biodiversity. For example, in the UK having roofs with vegetation is the decision of each owner and always supported by local authorities and municipal governments. In recent years, demand has been increasing and local governments are making an effort to get new urban developments to include green roofs in all newly built buildings.

A green cover reduces dust levels.

Another benefit of having green roofs is the roofs of buildings, is that dust levels in the atmosphere are reduced and therefore the air is cleaner.

As mentioned above, rooftop plants collect particles that are suspended in the air such as pollution from cities, heavy metals or all the organic compounds that are flying in the atmosphere. Whether plants collect all this pollution has a positive effect on air quality and therefore on people’s health.

“According to the United States Environmental Protection Agency EPA one square metre of vegetable cover helps absorb 0.2 kg per year of suspended particles”

Green roofs reduce CO2.

Having green covers makes the air quality of better quality as it reduces co2 from the atmosphere.

“According to the National Research Council of Canada, a square metre of a green roof can absorb 5 kilos of CO2 a year. Thanks to low energy consumption, carbon dioxide is reduced to 3.2 kg per year.” That is, a square meter of a roof with plant cover absorbs the same amount of CO2 that a vehicle emits on an 80 km course.

A cover with vegetation increases the durability of the cover.

The materials on which a green cover sits are more and better protected from damage from e.g. ultraviolet radiation or uvrays high temperatures.

The waterproofing system that has a green cover makes there a reduction due to wind wear, temperature changes, ultraviolet radiation …

A green cover reduces noise.

Green roofs have better sound insulation than a normal roof, therefore the houses are quieter.

The combination of soil, plants, and air that gets trapped inside these layers act as a barrier that isolates, absorbs, and deflects waves.

Green roofs have natural appearances and are you turn into useful spaces or agricultural spaces.

On a green roof you can design a terrace or a communal garden or even install a swimming pool or because not, install an urban garden. Studies say that a green cover has a psychological effect that relaxes and helps reduce people’s blood pressure and decrease pulsations.

The green roofs also increase the value of the properties as it goes from being a deck with nothing to a deck with a useful space.
