What is a Green Roof?
A green roof is a type of layered ballasted roof that consists of a growing medium and plants overlying a waterproof membrane. A green roof can replace a traditional roof and provide many benefits both immediately and over time.
The phenomenon known as the green roof is becoming more popular each year in an effort to reduce energy consumption, support biodiversity and make good use of typically unused space. Historically, green roofs — also known as ‘vegetated or ‘living’ roofs — appeared in parts of the world where building materials were limited, so turf was utilized as a roofing material. Today, green roofs replace a hard infrastructure with one that’s not only more efficient but also beautiful and useful.
It’s important to keep in mind that green roofs, like traditional roofs, require regular inspections to check for weathering, damage or drainage issues and to care for the vegetation. Like any garden, a green roof needs to be weeded and nurtured, fertilized and monitored to make sure that plants are healthy and the ecosystem is thriving.
