Green roofing has come a long way in the past ten years. A green roof, or living roof, is the roof of a building that is partially or completely covered with vegetation and a growing medium, planted on top of a waterproof membrane. It may also include additional layers such as a root barrier and drainage or irrigation systems.
Green roofing systems offer several benefits including:
- Lowering HVAC system strain and energy costs
- Minimizing urban heat island effects
- Reducing stormwater runoff
- Improving air quality
- Increasing waterproofing membrane longevity
