What is a green roof?

A green roof is defined as a rooftop that is intentionally covered with vegetation, which can include grasses, plants, and sometimes small trees. This practice integrates nature into urban environments, contributing to sustainability in various ways.

Green roofs provide numerous environmental benefits, including improved insulation, reduced urban heat island effect, and enhanced rainwater management. They can also support biodiversity by creating habitats for birds, insects, and other wildlife. Additionally, green roofs can contribute to energy efficiency in buildings by lowering the need for heating and cooling.

In contrast, a roof covered with solar panels focuses solely on energy production without integrating natural elements. A traditional rooftop with no modifications offers no benefits in terms of sustainability and vegetation. A roof made entirely of metal typically emphasizes durability and may reflect heat but does not contribute to the ecological benefits provided by green roofs. Thus, the best choice describing a green roof is one that highlights its characteristic feature of being covered with vegetation.
