Why Green Roofs?

Greener cities are healthier cities – and ZinCo green roofs can significantly contribute to making cities and buildings more livable by:

  • Improving air quality by absorbing greenhouse gases.
  • Absorbing sunlight, reducing cooling and heating costs for your building.
  • Capturing and helping manage storm water.
  • Reconnecting humans with nature.
