Spotlight on Green Roofing.

Ever seen a house that looked like it was sporting a toupee of grass? While there are varying degrees of green roofing, from partially covered to fully covered green roofing is a sustainable trend that has been on the rise in recent years.

Green roofs can be installed in place of or in complement to traditional roofing. The vegetation typically weighs more than traditional roofing so a structural engineer may be needed to verify that the building can support the weight. In addition, the plants may require a drainage or irrigation system and additional care must be taking to waterproof the area below the plants to prevent leaks that may damage the structure of the building.

Although the structure of the green roof is more complex, there are many benefits that come along with it. In addition to absorbing rainfall and helping to prevent runoff, green roofs also provide additional insulation which helps reduce heating and cooling costs. Green roofing also helps to reduce the heat island effect, filters pollutants and provides habitats for wildlife.
