The green roof market - Italy

1.1 Definition and presentation

A green roof is defined as a roof with vegetationas a result of the installation of a set of materials and plants that make up a microflora with a water drainage system. The installation of a green roof must be compatible with the roof structure (slab.....) and existing materials (concrete, wood....). A green roof consists of several layers: a waterproof membrane and a protective layer, laid over a traditional roof.

The technique was developed in the 1970s mainly in Scandinavian countries, Germany, Switzerland, and more recently in France and Belgium in the 1990s and 2000s. West Germany has been a pioneer in modern green roofing since the 1960s.stuttgart (Germany) is called the green roof capital of Europe.

Globally, the green roof market can be described as growing.

As for the global green roof market segment, it was worth nearly $7.19 billion in 2020, growing at a CAGR of 9.7 percent from 2017. By 2026, the global green roof market is estimated at $12.5 billion.

In Italy, the green roof market is growing even though it is growing much more slowly than in other countries.

There are different types of green roofs in the Italian territory: extensive, intensive and semi-extensive green roofs. The main differences between these roofs lie in the plant species present and the stratigraphy of construction.

A major advantage of these roofs is their beneficial contribution to the urban environment. In fact, the long-term benefits of green roofs include substantial energy cost savings, flood risk mitigation, creation of wildlife habitat, and combating city pollution. All of these features make these roofs a very desirable product for Italian consumers who are increasingly sensitive to respecting the environment and buying environmentally sustainable solutions for their lives.

Another advantage that these constructions have is the creation of new jobs for the Italian market; in fact, in addition to the workers involved in the construction of green roofs, gardeners and architects are also needed to engage in their maintenance.
