Green Roofs

Green Roof Systems

Green roofs serve several purposes for a building, such as absorbing rainwater, providing insulation, creating a habitat for wildlife, and helping to lower urban air temperatures and combat the heat island effect. At Everlast we have a proven track record of installing quality Green Roofs.

Other benefits of installing a Green Roof include:

  • Reducing storm water run-off, which in turn reduces the stress on urban sewer systems and decreases run-off related pollution of natural waterways
  • Insulating qualities mean reduced energy costs for building owners
  • Air quality improvement – lower rooftop temperatures mean less smog
  • Improved acoustic performance
  • Providing useable outdoor spaces
  • Extending the life of the roof system due to moderated temperature swings that cause a roof system to expand and contract, as well as protection from everyday wear and tear and UV degradation
  • Creation of habitat
  • Lowering your building’s carbon footprint
  • Reducing the energy requirements of a building

There are two types of green roofs: intensive roofs, which are thicker and can support a wider variety of plants but are heavier and require more maintenance, and extensive roofs, which are covered in a light layer of vegetation.


Green Roof technologies not only provide building owners with a proven return on investment, but also represent opportunities for significant social, economic and environmental benefits, particularly in cities.

Waterproof Protection

A Green Roof will protect the underlying waterproofing system from ultra-violet degradation and thermal shock. It is estimated that simply protecting the waterproofing system in this way will double the life expectancy, thus reducing future repair, maintenance and replacement costs.


Flat roofs are usually under-used in cities where land cost is at a premium, using the full building for a recreational space at roof level is an intelligent use of available space. The current is to encourage us to limit the effects of global warming by conserving energy is having the effect of persuading everyone to introduce more eco-friendly system such as green roofs, which can also improve thermal efficiency in buildings.

Bio Diverse Roofs

Bio Diverse roofs are similar to green roofs as they share many of the same benefits and construction methods, when a brown roof is designed, the overriding aim is to encourage biodiversity. Specific biodiversity aims can include:

  • Maximise the number of species living on the rooftop
  • Provide a habitat for specific species (e.g threatened species living on a brownfield site that a building is being constructed on)

It is a general misconception that bio diverse roofs are brown. They usually utilise local soil and spoil to provide the substrate for the roof, the roof will often initially be brown in colour, however, over time plant species will grow over this substrate and the end result will be a green coloured roof that nature has had a large hand in designing.
