Ideal for the flat, shallow-sided roofs of urban areas, green roofs can also be installed on some sloping roofs. There are a number of benefits to green roofs, including reduced energy costs, noise reduction, and increased life of the building’s existing roof.
Green roofs come in three different types: intensive, semi-intensive, and extensive. The types mainly differ by the depths of the planting material, which can range from 3 inches for extensive roofs to more than 24 inches for intensive roofs. The planting material depth also dictates how often it needs to be watered, the design of its irrigation, and what types of plants it will support.
Homeowners considering green roofing have a few things to consider, especially the high initial cost to waterproof and plant the roof as well as the roof’s increased weight. If after a careful assessment these costs are deemed feasible, a green roof is a great way for homeowners to cut back on greenhouse emissions and eliminate the heat island effect common in urban centers.
