What Kind of Green Roof?

Green flat roofs are becoming increasingly popular, and for good reason. They reduce energy costs by creating natural insulation, they create peaceful retreats and recreational areas, they provide natural habitats for wildlife, and they absorb storm water thereby reducing run-off into overworked sewer systems.

On a wider scale, in city environments, green roofs improve air quality by absorbing pollutants and by helping to reduce the urban heat island effect. City and suburban developments absorb and trap heat whereas evaporation from a green roof has been shown to cool surrounding air temperatures. A green roof must, like any roof, protect the building from the elements via a high quality, totally dependable waterproof membrane. 

Polyroof’s cold liquid-applied seamless membranes are ideal waterproofing solutions for use in green roof systems because they are flexible enough to easily accommodate structural movement as well as being lightweight and extremely durable. When used in a green roof system the durability of Polyroof membranes are even further extended since there is no UV penetration.

Extensive Green Roof System

Extensive Green Roof System

Typical features:
  • Most popular type of Green Roof
  • Typically finished with Sedum, Wild and Meadow Flowers
  • Low growing / Minimal maintenance
  • Lightweight
  • Shallow substrates
  • Ability to create Biodiverse environments
  • Variants include non-planted “brown roofs”
  • Not typically designed for public access
  • Intensive Green Roof System

    Intensive Green Roof System

    Typical features:
  • Used primarily as recreational space
  • Typically finished as a lawn, and can incorporate larger plants and shrubs
  • Higher Maintenance required
  • Heavyweight
  • Deep Substrates required
  • Often includes hard landscaping such as walkways, seating and planters
  • For limited or regular public access
  • Blue Roof Systems

    In addition to green roofs, blue roof system can be incorporated into the green roof design. Blue roof systems provide rainwater attenuation by collecting and controlling the discharge of rainwater from the roof contributing to Sustainable Urban Drainage System (SuDS) requirements. In many cases Blue roofs are incorporated in conjunction with an Extensive or Intensive Green Roof design. Blue roofs are increasingly popular choice in inner city and urban environments.

    1. Waterproofing that’s Proven to Last


    With proven lifespans in excess of 25 years, Polyroof systems are the number one choice for all green roof applications.

    2. Seamless, Maintenance-Free Waterproofing

    Polyroof systems are cold liquid-applied to form a continuous, seamless waterproofing membrane. This means there are none of the weak points associated with the lap joints of sheeted roof materials. 

    3. Lightweight & Fully Root-Resistant Membranes

    Load bearing often presents a particularly challenging aspect when designing a green roof. Weighing around 3.4 kg/m2 and available in innovative warm roof designs that do away with the need for over-decking or carrier layers, Polyroof waterproof membranes are as low in weight as they are high in performance.
