Green roofing has been around for thousands of years. Early green roofs consisted of moss, leaves and woven twigs to keep out the rain and later came reed or thatched roofing.
Modern green roofing is a bit different. Consisting of layers of material, today’s green roofs can help with urban rainwater management and reduce surface flooding in some areas. They can also provide a haven for wildlife, and this has in recent times contributed to its rise in popularity.
