One of the most incredible and fascinating things that the world of sustainable architecture has to offer is the green roof. And in today's post you'll understand why this whole wonder. But we've already made the point here that you run a serious risk of falling in love with this system and wanting to take it home too. Come with us you will not regret:
What is a green roof?
Until recently the construction of a house concerned only the future residents of the place. However, things have changed, and concern for more efficient and less environmentally friendly systems has created a need for sustainable, environmentally friendly projects that can benefit the entire community around the home.
And the green roof fits perfectly in this perspective of sustainable construction. To give you an idea, green roofs are currently one of the greatest references to sustainable architecture in the world, losing only to photovoltaic panels, an innovative system capable of capturing solar energy and transforming it into electrical energy.
Basically the green roof is a natural lining, usually made with grass, which covers the entire length of the house. In addition to being very aesthetic, the green roof has numerous environmental benefits that you will discover just below.
How does the green roof work?
The green roof consists of seven layers of different materials responsible for maintaining the correct absorption of rainwater, heat exchange and plant survival.
The first layer is the actual slab or roof itself. On it is placed a waterproof membrane so that the roof is protected against moisture. The third layer is a barrier against roots. This process step is important to prevent plant roots from damaging the roof structure.
Next comes the drainage layer. This layer ensures that all excess rainwater is drained properly avoiding flooding on the structure, the rotting of the plants and, of course, the infiltration of water into the residence.
After the drainage system comes the permeable tissue that allows the placement of the earth where, at last, a layer is placed with about seven to eight centimeters of substrate. At this stage, the roof is ready to receive the chosen vegetation.
Although this process seems simple, it is very important to have the help of a qualified professional. It is he who will be responsible for evaluating, among other things, the correct fall of the roof that must have at least 1,5% to guarantee adequate flow and the structure of the slab that must be strong and resistant enough to resist the weight of the vegetation .
Advantages of green roof

- In addition to thermal insulation, the green roof also has the function of acoustic insulation thus preventing the proliferation of noise into the interior of the house;
