Columbia Green Technologies provides the best green roof for your project, not a one-size-fi ts-all approach. Our systems maximize plant health, stormwater retention and drainage for a beautiful fi nished product long term.

BENEFITS OF A GREEN ROOF• Reduce stormwater runoff and delay the time in which runoff occurs helping cities struggling with aging

storm and sewer infrastructure

• Add plant biodiversity and provide habitat for pollinator species.

• Protects the roof membrane and at least doubles the life of the roof

• Bring year-round building energy savings by acting as a thermal blanket- green roofs provide cost savings

on a building’s heating and cooling bills

• Green roofs reduce the air temperature through evapotranspiration, reducing the urban heat island effect
