Green Roofs
Green Roofs are specially designed roofing systems that incorporate vegetation and soil over a waterproof membrane, providing a range of environmental, economic, and social benefits. Unlike traditional roofing materials like shingles or asphalt, green roofs offer a sustainable alternative by creating a layer of greenery atop buildings, enhancing urban biodiversity and aesthetics.
There are primarily two types of green roofs: extensive and intensive. Extensive green roofs are lightweight and low-maintenance, typically featuring drought-resistant plants and a shallow growing medium. They are ideal for retrofitting existing buildings or for large-scale installations. Intensive green roofs, on the other hand, are akin to rooftop gardens, requiring deeper soil, more diverse plant species, and greater care. They can even accommodate small trees and pathways, transforming rooftops into functional green spaces.
In addition to their beauty and versatility, green roofs contribute to reducing urban heat islands, managing stormwater runoff, improving air quality, and providing insulation which reduces energy costs. By incorporating green roofs, cities can enhance their sustainability efforts, promoting healthier, more resilient urban environments.
