 Living roofs are roofs with some sort of soil and vegetation on them. In Europe, there's a centuries-old tradition of turf roofs on the Atlantic coasts of Ireland and Scandinavia, for practical reasons – to keep the roof on in places where Atlantic gales would have blown off tiles or slates. Waterproofing was provided by a birch bark layer, overlain with turf. Living roofs are roofs with some sort of soil and vegetation on them.

 **Water retention:** a living roof can hold 60% of the precipitation that falls on it, which is then used by plants or evaporates. This slows the speed of runoff, and helps prevent flash floods. **Water retention:** a living roof can hold 60% of the precipitation that falls on it, which is then used by plants or evaporates.

 Finally, if you intend to install your own green roof, don’t feel intimidated. If you abide by basic principles regarding load and waterproofing, you'll be fine. If something goes wrong with the soil or the plants, it can be changed. If it’s not completely perfect, it will still provide a good habitat, and it will be too out of the way to be an eyesore. Finally, if you intend to install your own green roof, don’t feel intimidated.
