Modern green roofs are a rapidly developing commercial market in Ontario. Their primary benefit as a LID technology is in maximizing [[evapotranspiration]] for water balance targets.

Take a look at the downloadable Green Roofs Factsheet below for a .pdf overview of this LID Best Management Practice:

Green roofs are sometimes referred to as 'ecoroofs', 'vegetated roofs', or 'living roofs'.

Green roofs offer a variety of co-benefits beyond stormwater management. In urban centers they are often constructed to accommodate a roof terrace or amenity space. In this scenario the direct stormwater capture benefit is restricted to the areas with vegetation planted. Another increasingly popular use for rooftop space is for urban farming. Again, the direct stormwater capture benefit is restricted to the areas with planters.

To maximize the utility of a green roof as a low impact development tool, coverage with planting should be maximized. In many cases this means only inaccessible spaces are used.
