If you are building a new property or renovating an existing one and looking into roof options, you may be thinking about sustainable eco-friendly and energy-efficient options to help do your bit for the environment as well as saving yourself some pennies in the long-run.

Here are just a few options to consider. For more information and for free advice about a new or replacement eco-friendly roof, contact our specialist team at JP Franklin.

Eco-friendly roof options for New Zealand Properties


Warm Roofs

Traditionally NZ roofs have had insulation stuffed between the timber rafters/joints leaving a gap to allow air flow. This ventilation helps to avoid condensation which can lead to rotting decking and/or timbers, damp ceilings and damp insulation. However, it means heat is also lost in the process.

The warm deck flat roof system uses a combination of insulation and waterproof membrane to create your warm roof by putting the insulation on the outside of the timber deck structure. This design works by conserving heat so no ventilation is required, and there is nowhere for condensation to form.

Warm roofs provide you with not only a warmer and drier building environment, but one that is more energy efficient.

Cool Roof Technology – Solar Reflectance Painted Roofs

COLORSTEEL® prepainted steel is a high performing solar reflectance product. Developed specifically for commercial and industrial buildings, COLORSTEEL® Bounce™ has been optimised to provide a thermal performance of 77%.

In summer, the technology in COLORSTEEL® Bounce™ paint works to reflect the sun’s heat allowing both your roof and the environment inside your building to stay cooler on hot days. It performs like extra insulation, making it easier for air conditioning to keep buildings cool.

COLORSTEEL® Bounce™ absorbs less heat on hot days, working to protect your roof and its supporting structure from temperature extremes. Lower thermal stresses can help your roof to last longer.

Roof Garden

A roof garden is a roof that is partially or completely covered with vegetation and soil; lined by a membrane that ensures the living space below remains watertight. Benefits include:

  • Reduces storm water runoff
  • Purifies air
  • Protects roof membrane from climatic extremes
  • Sound and temperature control
  • Insulates and shades building
  • Provides a pleasant outdoor area

There are many factors to consider when planning a roof garden, including getting and correctly installing an appropriate waterproofing membrane, installing a proven effective drainage system, buying the correct type of soil and plants, and deciding on a maintenance schedule.

Green Star Roofs

The Green Star NZ rating System was introduced to New Zealand by the New Zealand Green Building Council (NZGBC) and is derived from the Australian Green Star rating system, LEED rating tool used by the US and the British BREEAM rating system. It contains a number of environmental measurement criteria, which collectively determine the environmental rating for a building

Green Star NZ was created to establish a common language and standard of measurement for green buildings, promote integrated whole-building design, raise awareness of green building benefits, recognise environmental leadership and reduce the environmental impact of development.

Contact us at JP Franklin to discuss how we can help you achieve a green star roof for your commercial or industrial building.

Other ways to ensure your roof and property are eco-friendly and efficient include using more recycled materials, energy-efficient materials, inspecting your roof regularly for signs of leaks, and keeping on top of your roof maintenance.
