Revitalising ageing roofs through innovative renewal techniques offers a sustainable solution that extends building lifespans, reduces waste, and minimises environmental impact in the construction industry.

Green Roofs are a complex system that requires careful consideration of multiple factors, including weight, water retention, and the type of vegetation.

Explore the benefits of metal tray substrates compared to traditional plywood substrates in flat roofing applications, focusing on value engineering, efficiency, and long-term performance.

This article highlights the importance of reconsidering traditional flat roof designs to achieve cost-efficiency and performance through the elimination of internal guttering systems.

Recent membrane testing and technology allows some systems to work at lower falls. This creates an impact on the design scenarios in which the overall roof buildup has a height limitation.

A ballast roof or brown roof is created when a roofing membrane has a layer of gravel, pebbles, or stones added as the finished layer.

It is important to consider future factors such as ground movement and rising sea levels to ensure the waterproofing membrane specified will perform as intended regardless of changes in ground conditions.

A look at the considerations for redeveloping brown fields. 

With the growing awareness of Passive House principles, we can now illustrate the wider benefits of warm roof design.

We recently conducted a simple experiment comparing the temperature of different coloured membranes in the Auckland sun.
