Green Roofs

Green roofs are an emerging trend in eco-friendly buildings, especially for those looking to achieve LEED certification. A green roof is a roof that is partially or completely covered with vegetation and soil, planted over a waterproofing or roof repellant layer. The term green roofs is also sometimes used to signify roofs that utilize green technologies such as solar panels.

Green roofs, also known as vegetated roofs, have much longer material lifespan then standard roofs. Lasting up to twice as long as conventional roofs, maintenance costs are decreased and you save in replacement costs. Sound insulation is improved with the soil and plants that work as a noise buffer. These same plants improve outdoor air quality as well, helping absorb contaminants. Other sustainable benefits directly relate to LEED credits.

Vegetated roofs help maintain natural storm water flows by promoting infiltration. This strategy helps achieve LEED Sustainable Sites Credit 6.1-Stormwater Design, Quantity control. Sustainable Sites Credit 7.1-Heat Island Effect, Non-Roof can also be attained because green roofs minimize the heat island effect. A green roof can also provide a habitat for birds. Providing a habitat and promoting biodiversity within the area of your building helps achieve Sustainable Sites Credit 5.1-Site Development, Protect or Restore Habitat. Using roof runoff efficiently from a green roof can also contribute to Water Efficiency Credit 2-Innovative Wastewater technologies. Using a green roof is an economically efficient and environmentally friendly resource that can help knock out multiple LEED credits.
