A green roof or covering is the product to landscape or allow plants to grow and develop on the roof of a house or covering of a building. At the same time, this type of facilities favours the settlement of natural habitats for insects or animal species that help biodiversity.
The benefits of green roofs or coverings in buildings, generally developed in the cities, are evident for the environment and for the maintenance of the building itself (saving water, energy or electricity) and its contribution to sustainable urban development.
The implementation of a green roof in a building is, definitively, creating awareness in terms of the new construction and the reassessment of nature as an element of the fight against climate change.
A green covering helps to control the drainage and the runoff decreasing the risks of flooding in the construction environment, it reduces the heat in summer and the cold in winter (by up to 7ºC in difference inside the home), it also provides good insulation from environmental sound, filters the atmospheric dust, reduces CO2 and produces oxygen, among other benefits for people and the environment.
But the benefits a green roof provides are as important as the care of the technical aspects in its construction, as well as in the selection of materials such as the choice of plants that shall be implemented.
Materials:
When it comes to choosing a system of garden roof, it needs to be remembered that the drainage sheets and other materials are specifically conceived for the proposed gardening system, otherwise, problems would arise in the short- and medium-term.
The roof gardens which we work with have an urban water management system that is very safe and efficient, and although there will be a small supply of water at first, the plants shall be self-sufficient, as the system shall preserve all the rainwater required to sustain it.
Plants:
They are selected for each project according to 4 parameters:
Water needs, in planting and during their useful life.
Adaptation to the climate of the place, especially to temperatures and wind
Availability of native species
Aesthetic and biological aspects, colours, shapes, radicular system, flowering, etc.
Execution of the work:
Being careful with each detail during the execution of a landscaped roof is essential to achieve a good result. The problems that may generate a poorly-completed roof, with deficiencies in impermeability and drainage, may also be costly, a real headache for the owners.
Knowledge and experience in managing the technical aspects when it comes to building green roofs is a key element in making sure that the final results are those that are truly desired.
At DRIM Medi Ambient, we guarantee the end result of your green roof, thanks to many years of experience and greatly-satisfied customers.
