Green Roof Systems
Sustainable solution for modern buildings
Green roofs are complete building systems used to protect waterproofing, manage rainwater and improve the thermal behavior of buildings. They are applicable in both new and retrofit projects.
Why use green roofs?
Limits roof overheating in warm seasons
Reduces thermal stresses on the waterproofing
Contributes to the retention and controlled discharge of rainwater
Protects the waterproofing layer from UV radiation
Improves the thermal comfort of under-roof spaces

Composition of the green roof system
A complete system includes:
vegetation
culture substrate
filter layer
drainage layer
protective coating
waterproofing
resistance structure
The exact structure depends on the slope and the type of green roof chosen.
What you need to know moving forward with a green roof
A green roof is primarily chosen according to the structure of the building and its use, not the type of vegetation. Each solution involves different loads, maintenance requirements and long-term costs. For a right choice, the following should be analyzed:
floor bearing capacity
roof slope and drainage details
type of system: extensive, semi-intensive or intensive
the level of long-term maintenance assumed
the need for permanent or occasional irrigation
conditions of exposure and use (access, traffic, climate)
The final decision is based on the technical design and structural calculations, not on aesthetic preferences. These are determined later, within the limits of the correct technical solution.
Frequently Asked Questions
Is green roof suitable for my building?
It depends on the structure of the building and the slope of the roof. The solution is technically determined, not by aesthetic preferences.
How hard is a green roof?
Weight differs depending on the system chosen. Extensive systems are lightweight, intensive systems require a properly dimensioned load-bearing structure.
Does green roofs affect waterproofing?
No. A correctly designed system protects the waterproofing and extends its life.
What maintenance does a green roof require?
From minimal interventions, a few checks a year, to regular maintenance, similar to a classic green space. The choice is yours.
Is irrigation needed?
For extensive systems, only occasionally. For semi-intensive and intensive systems, irrigation is part of the project.
Does a green roof cut energy costs?
Yes. Contributes to thermal insulation and reduces temperature variations.
