Living Roofs

Living Roof Systems

A living roof, also known as a green roof, is an ideal way to contribute to delivery of sustainable architecture. A living roof provides environmental benefits, lowers urban air pollution, grants access to green space, improves general well-being, and reduces energy consumption of the building.

Axter’s living roof systems are engineered to accommodate the most varied ecological and environmental requirements. The combination of horticultural expertise with long term system performance ensures total compliance with all local, national and project specific environmental, biodiversity and attenuation criteria.

Green roofs reduce ambient temperatures and improve rainwater management by absorbing rainfall to reduce flooding. They enhance biodiversity through habitat provision, are visually attractive, provide amenity for residents who may not have access to private gardens and provide opportunities to grow food.

Things to consider when planning a green roof:

  • The roof must be capable of supporting the design load
  • There must be adequate provision to drain excess rainwater
  • Safe access for maintenance must be included in the design
  • The roof waterproofing must be robust and long lasting
  • Anti-root / root resistant membranes must be considered
  • Outlets must be capable of inspection

Living roofs are generally categorised as Extensive or Intensive, however we also offer Biodiverse (Brown) systems that promote and increase local biodiversity, as well as versatile Modular systems to aid installation. Read more about our different green roofs below.


There is currently no UK legislation demanding roof greening, however, individual cities are now advocating green roofs. The London Plan, Chapter 5: London’s Response To Climate Change: Policy 5.11 states; Major development proposals should be designed to include roof, wall and site planting, especially green roofs and walls where feasible, to deliver as many of the following objectives as possible:

a) adaptation to climate change (ie aiding cooling)

b) sustainable urban drainage

c) mitigation of climate change (ie aiding energy efficiency)

d) enhancement of biodiversity

e) accessible roof space

f) improvements to appearance and resilience of the building

g) growing food.

Local Development Frameworks (LDF’s) within London Boroughs are also encouraged to develop more detailed policies and proposals to support the development of green roofs and the greening of development sites particularly in smaller developments, renovations and extensions.

Furthermore, Axter living roof systems will, with certain conditions, automatically be awarded one credit under The Building Research Establishment Environmental Assessment Method (BREEAM) sub-sections LE 03 Mitigating Ecological Impact, LE 04 Enhancing Site Ecology, LE 05 Long Term Impact on Biodiversity and SUR1 Surface Water Management.


Both warm and inverted roofs can be employed for all Axter green roof types though extensive roofs, principally designed for biodiversity, would normally be installed on a warm roof Cityflor® system assembly. Intensive roofs, principally designed for amenity value, would normally be installed on an inverted roof Wilotekt®-Plus or Force® Dalle system assembly.

Installation of Axter living roof systems is carried out by accredited Axtershield Installers. All system components are specified and installed to ensure compatibility, single source responsibility, and compliance with Axter recommendations and the Green Roof Organisation (GRO) Code.


All Axter living roof systems achieve comprehensive guarantees. The guarantee length and type will be dependent on the waterproofing system selected and the variety of green roof finish chosen.


  • Reduces storm water runoff as part of a sustainable drainage system (SuDS) strategy
  • Dramatically increases life expectancy of roof waterproofing
  • Reduces building energy use
  • Mitigates the effects of climate change
  • Increases urban biodiversity and wildlife conservation
  • Lessens the Urban Heat Island Effect (UHIE)
  • Improves air and water quality
  • Reduces sound transfer
  • Provides green amenity space
  • Aesthetically pleasing, with a wide variety of plant options
