I really like them green roofs!

We had a customer this summer ask us for a green roof, but when I started showing her rooflights and skylights I soon realised she didnt want to save on her electricity bills. She wanted a GREEN roof!

Sedum roofs as they are known is a living roof! They are 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 and drainage and irrigation systems.

Green roofs can improve stormwater management by reducing runoff and improving water quality, conserve energy, mitigate the urban heat island, increase longevity of roofing membranes, reduce noise and air pollution, sequester carbon, increase urban biodiversity by providing habitat for wildlife

If you are windering how much they cost, we estimate that the cost of installing a green roof starts at around £15 per square foot for simpler extensive roofing, and £30 per square foot for intensive roofs.

Planning permission? No. Most of the time where green roofs are installed on existing buildings, planning permission is not required. However, it is always advisable when making any kind of alteration to a building to contact your local planning department.

Can you have one? Most likely! But we need to take into account the following

  • Climate, especially temperature and rainfall patterns.
  • Microclimates on the roof top.
  • Strength of the supporting structure.
  • Size, slope, height and directional orientation of the roof.
  • Type of underlying waterproofing.

Green roof we installed this summer! I have heard from the customer that is has grown considerably since we installed it but still requires no maintenance!
