Green roof (Vegetable)

The green roof is a structure that is covered with vegetation. It is usually a flat roof or a roof with a very small slope. This alternative is very appreciated for its freshness, especially when the weather is nice. Especially since it is an ecological solution that helps limit the effects of pollution.

The characteristics of the green roof

This structure is often adopted for its aesthetic appeal. But it also has some practical features. Indeed, it is a roof that can contribute to the waterproofing and insulation of different types of buildings: residential, commercial, industrial or institutional.

There are three different types of green roof plantings:

  • Intensive: this planting is characterized by a deep substrate supported by a resistant structure. Different varieties of plants can grow there, be it vegetables, flowers or trees;
  • Semi-intensive: the substrate is lighter for this type of planting. There is a choice between herbs and flowers in terms of what crops to consider;
  • Extensive: the substrate is the lightest of all. The roof will then accommodate only a few plants. This is the most affordable plantation in terms of price.

How to maintain a green roof?

Maintaining a worm roof is quite demanding, compared to another structure such as a shingle roof or a metal roof. In all cases, maintenance must be undertaken on a regular basis and the insurer must be informed.

Various measures must be taken to optimize maintenance:

  • For an intensive plantation: an irrigation system is set up and maintained by a technician. The owner must, for his part, be assiduous in watering;
  • For extensive planting: regular weeding is required and the waterproofing membrane must be repaired as soon as necessary.
