Is Your Roof Suitable for a Rooftop Garden?

Theoretically, any roof surface can be greened — even sloped or curved roofs can support a layer of sod or wildflowers.

Certainly, a flat roof, approximating level ground conditions, is the easiest on which to grow a garden, though a slight slant can be helpful in allowing drainage.

Also consider how much weight your roof can bear. A simple, lightweight rooftop garden will weigh between 13 and 30 pounds per square foot. Add to this your own weight — or that of anyone who will be tending or enjoying the garden — gardening tools, and, if you live in a colder climate, the additional weight of snow in the winter.
