roofing systems

Vegetative Roof

A green roof or living roof is a roof of a building that is partially or completely covered with vegetation and a growing medium, planted over a waterproofing membrane. It may also include additional layers such as a root barrier, drainage system, or an irrigation system. 


  • Building incentives – government agencies have been providing incentives to help offset the cost of a green roof
  • Stormwater retention – this will decrease impact on existing sewer systems and potentially reduce water runoff by 40%-95%
  • Thermal Resistance – especially during warmer months as it can reduce the buildings cooling cost 
  • Reduction of pollution and noise levels – filter out dust and smog as well as filter the rainwater nitrates 
  • Additional space – can increase the building value by making more space for building occupants
