With over 20 years of experience designing and building green roofs, Vegetal i.D. enables you to implement a beautiful, reliable, and high-performance green roof in even the most technical projects!

The Key Points of a Green Roof Project

When designing a green roof system it is essential to take into account certain aspects of the rooftop in order to design the most suitable solution:

  • General technical constraints of the project: climate, type of vegetation, roof type, the load-bearing aspect, the pitch of the roof, etc.
  • Specific technical constraints: local regulations, project accessibility, reflective walls along the green roof roof, adjacent roofs draining onto the green roof, etc.
  • The project manager's aesthetic and ecological wishes, the desired level of maintenance, etc.

1 Green Roof Project = 1 Customised Solution by Vegetal i.D.

Depending on these criteria, the Vegetal i.D. engineers and technicians conduct an in-depth technical study in order to:

  • Choose the most suitable vegetation for a project and its specific constraints (climate, medium, pitch, etc.). By varying the type of drainage, growing media and vegetating technique, and by adapting the depth of the growing medium used. There are many Vegetal i.D.® multilayer green solutions.
  • Define the methods of implementing the solution
  • Define the structural dimensions, building, facades, slopes, etc.
  • Establish the irrigation requirements and recommend a suitable irrigation solution if necessary
  • Determine rainwater management benefits
  • Define maintenance requirements
