If asked to choose between the traditional roof covering materials like shingles, tiles, cedar shakes, etc. and plants that create soothing foliage as roof cover, many people would opt for the latter for reasons of eco-friendliness. As the modern lifestyle keeps building up carbon footprints at an alarming rate, green roofs provide a unique opportunity to reduce it and the reason behind its popularity. Modern builders are keen to address the environmental problems and inclined to install green roofs which revive very old memories of the Vikings exploring the North Atlantic region when they built grass-covered sod homes wherever they went. Therefore, the concept of green roof is nothing new except that today it has become instrumental in dealing with the environmental distress that surrounds and gives hope of improving it.
The low environmental impact of modern green roofs is driving more and more homeowners towards it. The modern technology of green roof originated in Germany in the late eighties and soon spread across Europe and America, and today, anyone with the good intention of improving the environment can install a green roof.

Types of green roof
A standard green roof consists of five basic layers that begin with the roof deck upon which are the other layers of waterproof membrane and soil filter fabric that supports several layers of lightweight soil mix on which is planted drought-resistant plants. There are two types of green roof – an extensive green roof and an intensive green roof.
Extensive green roof – A humble looking low profile green roof that is more for functional purpose with limited access to homeowners is what comprises extensive green roof. The primary purpose of the roof is to produce a green cover in the most basic form and consists of a 3-inch deep soil mixture that helps the greenery to grow upon it. This green roof is much lighter and costs less. Planting an only limited variety of plants that are just enough to create the green cover with very little maintenance helps to make both ends meet. Sedums that have water-storing leaves and can cover the ground while maintaining low height is the most preferred plant for installing an extensive green roof.
