Why choose Green Roofs?

Did you know that you can enjoy the pleasure of being in touch with nature in your home in the city?


Prudêncio launches the challenge: improve your ecological awareness by adopting, whenever possible, green roofs in the renovation of the existing building and by including them in new projects and enjoy the environment they provide.


Our specialized team proposes the integral solution, from the system of waterproofing, insulation, and drainage to the project and creation of the garden or green space.




Learn the advantages of this solution:


  • Better thermal insulation and energy saving: A green roof increases the insulation and energy efficiency of the building. Due to their properties, they minimize energy flows between the exterior and interior. They provide greater comfort and a remarkable reduction of energy costs – heating in the winter and air conditioning in summer.
  • Better absorption and sound insulation: The vegetation layer and the design of the system effectively reduce ambient and impact noise levels caused by hail, rain, people moving, or furniture.
  • Increases life expectancy: Green roofs protect waterproofing membranes and other materials from UV and IR rays, ozone as well as perforations and physical damage. It also protects the building from extreme temperature variations, extending its service life and limiting the need for expensive maintenance.
  • Better urbanism and living space: A living roof favors the return of nature to the city, inviting birds, butterflies, and other fauna to create a new habitat on the roof. On the other hand, it offers the inhabitants functional and relaxing spaces.
  • Better air quality, better urban climate: The vegetation filters and absorbs polluted air particles such as Co2, dust, and heavy metals and produces oxygen. It also makes possible the gradual release of moisture which contributes to the improvement of the air and to the balance of the ambient temperature.
  • Water-saving and lower load on urban drainage networks: Vegetable roofs absorb large amounts of rainwater and delay its flow, reducing flow and pressure on the pipes and the consequent risk of flooding or transshipment of sewage. Promotes water saving by decreasing watering cycles.


The solution:




  1. Resistant structure – with the capacity to support the composition of the system, namely the substrate load and vegetation.
  2. Shape layer – which, like any flat roof, should ensure a slope of 2%, as well as a regular and consistent base.
  3. Waterproofing system – of membranes in TPO, modified bitumen, or PVC.
  4. Thermal insulation – although the vegetal layer works as an insulator due to its low thermal conductivity, it is advisable to apply thermal insulation to reinforce the effectiveness of the system.
  5. Drainage layer – with the function of ensuring the flow of superfluous water and storing that necessary for the vegetal layer.
  6. Filter layer – prevents filling of the drainage layer with particles of the substrate. It should have high permeability to water and resistance to mechanical actions.
  7. Substrate and vegetal layer – that will vary according to the typology of the green cover to be installed – Extensive, Semi-Intensive, or Intensive.
