Sempergreen® Traditional Green Roof

Minimum order 10m2

This system includes 3 layers:

  • Sedum blanket
  • Roof Garden Substrate
  • Drainage

The build-up of this traditional green roof system creates a beautifully sustainable green roof.  The 50mm roof garden substrate layer is developed to FLL guidelines and is a nutrient-rich substrate, ensuring healthy and strong sedum plants. There are 6-8 different species of hardy succulents, each has been chosen over many years of growing experience by Sempergreen, for their ability to absorb and retain water, and thrive in adverse weather conditions. The plants are grown on a coco fibre matting using a special cultivation substrate, over a 12 month period. The sedum blankets in this system provide a minimum of 95% plant coverage, ensuring that an instant green roof is achieved.

If you are creating a gravel border around the roof edges, sky lights, lanterns or drainage areas, it is important to add an additional drainage layer to sit beneath the gravel.

Ideal for: Domestic & commercial roofs, garden rooms, flat roofs 3 – 15°.
