As part of a sustainable development approach, the trend for green roofs is growing more and more in urban areas.

This development, as beautiful as it is, nevertheless requires careful preparation and a certain investment. Are you looking to know the price of a green roof and advice for its installation?

Detailed analysis of the cost of a green roof
The cost of a green roof depends on several factors. The price varies mainly depending on the size of the roof, the type of greening chosen and the preliminary work necessary to install the greening. Depending on these criteria, the cost can range from 50 to 200 euros per square meter.

Furthermore, the choice of type of vegetation has a major impact on the cost. There are mainly two types of green roofs: so-called “extensive” roofs and “intensive” roofs. The former are simpler to install and require less maintenance, their cost is therefore logically lower. The latter require regular maintenance, with more luxuriant vegetation, they are in fact more expensive.
Finally, in addition to the revegetation itself, preparatory work may be necessary, which leads to an increase in costs. In particular, it is necessary to check the resistance of the roof, install additional insulation, or even provide a drainage system. Additional costs must also be taken into account, such as improving the waterproofing of the roof or the costs associated with the possible obligation to reinforce the building structure.
