The primary advantage of using a green roof lies in its ability to enhance building insulation and support biodiversity. Green roofs not only provide an additional layer of insulation, which can help reduce heating and cooling costs by moderating indoor temperatures, but they also contribute positively to the environment. The vegetation on green roofs absorbs rainwater, reduces runoff, and improves air quality, all of which promote a healthier ecosystem. Moreover, green roofs can create habitats for various species, thus supporting local biodiversity.

This dual benefit of insulation and ecological support is a key reason why many builders, architects, and environmentalists advocate for the use of green roofs in urban development. The other options do not accurately reflect the comprehensive advantages that green roofs offer. For instance, while they can be low maintenance, they do still require some level of upkeep. Additionally, green roofs are often more costly than traditional roofing solutions, and they do not reflect all sunlight; rather, they absorb and utilize it for the growth of plants.
