Green Roofing
Green roofing systems or a living roof is a roof that is partially or completely covered with vegetation and a growing medium, installed over a waterproofing membrane. There are various different types of green roof system including
  • Extensive green roof system, a light weight system which includes a shallow growing medium. This type of green roof system is the most economical to install and also maintain. We can supply your total extensive green roof, with a variety of sedum blankets for different conditions or preferences. Our blankets can include sedum species native to the British Isles, native wild flower, ornamental grasses and culinary herbs to add a scent to your roof garden. We also supply cuttings, plug plants and even hydro seeding solutions for larger roofs. The environmental benefits of green roofing are well known but it’s also got to look right. Our expertise in Green Roofs will ensure that your client has a roof worth looking at and looking after.
  • Intensive green roof system, a deeper layer of growing medium is required >200mm. Plug planting of varying species of plants, shrubs or trees can be installed in this type of system. Generally irrigation systems are required. If the green roof is to be used as a recreational area, walked upon, or forms part of a landscaping aesthetic, then an intensive green roof would be preferable.The green roof system is BBA certified as an assembly, giving you peace of mind that you are choosing a green roof that will stand the test of time.

The benefits of green roof systems?
  • Creates a natural habitat for flora and fauna
  • Aids biodiversity encouraging a wider spread of species in the area
  • Soft landscaping helps to reduce the risk of flooding by retaining large proportions of annual rainfall and reducing rainwater run-off. Particularly useful within Sustainable Urban Drainage (SUDs) schemes
  • Environmental masking blends the building into its surroundings
  • Improved air quality as vegetation assists in reducing both gaseous pollutants and dust particles
  • Reduces urban heat island effect (the difference in temperature between urban areas and the surrounding countryside) through absorption of some of this heat and the natural evaporation of water from plants and soil
  • Reduces building’s carbon footprint through lowering building running costs
  • Reduced construction costs: no requirement for screed on the deck reducing the overall weight imposed, fewer rainwater outlets, decreased rainwater drainage system capacity and a reduced requirement for storm water attenuation within the SUDs scheme for the site
  • Increased life expectancy of waterproofing membranes when protected by green roof landscaping
  • Many local authorities favour planning proposals that incorporate green roofs within the application, particularly if it meets their policies towards providing a sustainable environment
  • Increased property value – roof usage can be maximised for purposes including leisure, and offers unique potential for replacing the land lost to the building’s footprint
  • Noise reduction for the building – green roofs have excellent acoustic qualities for both external sound (up to 3dB) and internal noise up to 8dB)
