What Are Cool Roofs?
Commercial roof repair, restoration, painting and maintenance projects have never been easier, thanks to Dulux® Acratex® Commercial Roofing Solutions.
The University of NSW* study found that cool roofs can help maintain cooler indoor conditions and enhance occupant comfort, especially in heat-vulnerable buildings.
Examples of average energy savings per capital city:
- Sydney: 22.2–39.9 kWh/m² (34.7–42.3%)
- Melbourne: 4.0–9.7 kWh/m² (12.3–27.6%)
- Brisbane: 34.2–52.2 kWh/m² (33.8–39.4%)
Dulux Acratex Cool Roof Commercial White is engineered to maximise solar reflectance, making it ideal for improving existing surfaces, including weathered Galvanised or Zincalume roof surfaces. This approach can contribute to reducing the Urban Heat Island effect and improving thermal performance across built environments.
A selection of Dulux Acratex Roof Membrane colours also meet the Green Star Solar Reflectance Index (SRI) criteria.

Cool Roof Coatings
One of the most accessible ways to cool your building is by applying a heat-reflective roof coating. Dulux Acratex Cool Roof Commercial White is designed for high solar reflectance and UV resistance, helping reduce heat absorption. Suitable for a range of roof types including corrugated iron, Zincalume® and Colorbond®, it’s an ideal solution for commercial buildings looking to improve comfort, efficiency and long-term performance. A heat reflective coating can form part of a heat resilience strategy and support efforts to mitigate the Urban Heat Island effect.
Cool Roofs vs roof replacement
Applying a heat-reflective roof coating can be a cost-effective alternative to full roof replacement. On commercial metal roofs with visible surface wear, Dulux Acratex roof coating systems can seal and protect the substrate to help limit further deterioration, support structural performance and extend the roof’s service life, while also reducing heat absorption.

Speak to an expert ↪Cool Roofs and commercial roof restoration
Cool roof coatings are often used as part of commercial roof restoration projects. A typical process includes these steps:
-
Assessing the roof for leaks, rust and structural issues.
-
Pressure washing and treating rusted areas.
-
Applying the reflective roof coating using the correct system and professional equipment to ensure optimal performance.
This approach not only revitalises the roof but also ensures compliance with energy efficiency standards and may contribute to cooler indoor conditions.
Dulux Acratex Cool Roof Commercial White
Dulux Acratex Cool Roof Commercial White reflects the sun’s energy before it is absorbed and converted as heat into occupancy zones. It has been specifically formulated for low dirt pickup with added mould and algae protection and a low sheen finish to reduce glare. Coatings with high solar reflectivity can improve cooling efficiency.

Dulux Acratex Cool Roof Residential with InfraCool Technology
To maximise reflectivity we recommend choosing a lighter colour with low solar absorptance high solar reflectivity. Where a darker colour is preferred, then consider choosing from the Dulux Acratex Cool Roof Residential with InfraCool Technology range. Colours in this range have higher Solar Reflectance when compared with the same colour tinted into most standard roof coatings.
