Green roofs are becoming increasingly a prerequisite for planning approval, either through biodiversity action plans, flood risk reduction as part of sustainable drainage systems or legislation.


Green roofing systems are principally divided into three main categories:

  • Biodiverse
  • Extensive
  • Intensive


Whichever type of green roof is specified Sika-Trocal recommend the use of a warm ballasted system, as this reduces the insulation thickness and effectively controls vapour diffusion. This is critical in a roofing system that will always contain moisture above the primary waterproofing membrane.


As experts in roofing Sika-Trocal choose to work with experts in horticulture to provide self sustaining plant communities on the roof.
