Blackdown Biodiverse Green Roof

Key Features & Applications

• Blackdown biodiverse roofs are suitable for lightweight roof decks, inaccessible roofs, flat or shallow sloping roofs and are equally suited to re-roofing or new build projects
• They are versatile, economic and support a wide range of native and non-native plant species; so encouraging biodiversity. They can also help reduce stormwater run-off
• Blackdown green roofs comply with the GRO Green Roof Code of Best Practice 2011 and the German Landscaping and Landscape Development Research Facility (FLL) Guidelines

Design, Planting & Waterproofing

• Biodiverse roofs have a typical build-up height of 80–200mm (including drainage layer) and do not typically require irrigation once the plant material is established
• Planting can include grasses, wildflowers, succulents and herb species. Additionally, organic material such as logs, shelter stones and piles of sand and gravel can be incorprated into the substrate to encourage invertebrates
• The brown roof variant recreates conditions of reclaimed brown field sites
• Waterproofing options include Derbigum membranes, Euroroof Mastergold membranes, Hydrotech structural waterproofing and standing seam roofing
