Green roofs are lightweight, low-maintenance vegetated roof systems used as a cost-efficient, eco-sensitive alternative to conventional roofing. A proven technology that has been used in Europe for half a century, Green roofs work with almost any type of architectural structure, including most types of commercial, multifamily and industrial buildings, as well as single-family dwellings and garages.

Green roofing offers an attractive alternative to the barren deserts of tar, gravel and asphalt usually seen from urban windows. Publicly accessible green roofs provide needed urban greenspace fostering community gathering and recreation. Green roof technology offers an attractive, cost-effective method for addressing rising utility costs caused by increased development, summer shortages and the Urban Heat Island effect. The process can easily pay for itself over the long term.

A Green roof captures and evaporates up to 100 percent of the rain that falls on it, reducing the volume and speed of stormwater runoff that leaves a site, which in turn helps protect our local rivers and streams and prevents sewer overflows. This makes it ideal for urban settings in which high-density development offers few opportunities for rainwater to percolate into the soil during storms. Green roofs also provide acoustic insulation, reduce glare, and are effective air filters, removing airborne dust particles.

But they're not just great for the environment . . . green roofs are a cost-effective investment that protects a roof's structural elements and extends its longevity!
