Green roofing represents a range of technological solutions to conventional roofing that provides improved energy efficiency and uses more environmentally friendly or sustainable materials. Commonly available roofing materials such as slate, metal, and clay have higher environmental benefit when selected over asphalt and even wood due in part to their reusable or recycled content and their longevity. The addition of composite roofing products made exclusively from reclaimed and recycled materials such as tires, plastics, and sawdust provides a variety of green roofing options. The system most commonly referred to as a “green roof” replaces roofing tiles with planted vegetation as a way to provide a variety of environmental benefits, including energy efficiency, insulation, storm water management, pollution reduction, and increased wildlife habitat and green space.
