How Heat Reflective Roof Coatings Can Lower Your Energy Bills

Let’s face it — Queensland summers can be brutal.


When the sun is beating down, your roof is the first point of contact. And if your roof is absorbing all that heat? It doesn’t take long before your home starts feeling like an oven — and your energy bills skyrocket.


This is where heat reflective roof coatings come in.


These specialised coatings don’t just make your roof look good — they actively help to lower internal temperatures and reduce cooling costs. Here’s how.


What Is Heat Reflective Roof Paint?

Unlike standard paint, heat reflective coatings (like Roofcote Supa Cool) contain additives that reflect more of the sun’s rays — particularly infrared radiation, which is responsible for heat gain.


By reflecting heat away instead of absorbing it, your roof stays cooler — and so does your ceiling space.


How Much Can It Lower Your Energy Bills?

While savings depend on roof colour, insulation, and home design, many Brisbane homeowners report:

  • Reduced reliance on air-conditioning
  • Internal temperature drops of 5–10°C on hot days
  • Noticeably cooler rooms in summer afternoons


Over time, this can mean real savings — especially during long heatwaves.


Benefits Beyond Just Temperature

  • UV Protection: Heat reflective coatings protect your roof from UV breakdown, helping it last longer.
  • Improved Comfort: Even without aircon, your home feels more liveable.
  • Environmental Impact: Less energy use = reduced carbon footprint.
  • Aesthetic Upgrade: You can choose from a range of colours without sacrificing performance.


Ideal Roof Types for Reflective Coatings

  • Metal roofs (Colorbond and Zincalume)
  • Concrete tiled roofs
  • Terracotta roofs with specialist products


At JMZ, we’ll assess your roof material and advise on the most suitable coating.


Roofcote Supa Cool: Built for Queensland Heat

We proudly apply Roofcote Supa Cool, an Australian-made heat reflective membrane designed specifically for harsh local climates.


It’s not just marketing hype — it’s backed by performance testing and over 30 years of success in South East Queensland.


Does Colour Still Matter?

Yes — lighter colours still reflect more heat naturally. But with reflective technology, even darker tones can perform surprisingly well compared to traditional paints.


“We’ve had clients in Brisbane’s western suburbs cut their summer cooling bills by 15–25% after a reflective roof coating.”


Want to Know If It’s Worth It for Your Home?

Have you noticed your metal roof looking faded, flaky, or even patchy? Peeling roof paint isn’t just an eyesore — it’s a warning sign that your home’s biggest shield is vulnerable. In Queensland’s extreme climate, metal roof coatings break down faster than many people realise. Let’s look at why metal roof paint peels, what it means for your home, and most importantly, how to fix it properly so it lasts. The Real Reason Metal Roof Paint Peels in Queensland Most people assume peeling is just about age. But in reality, it’s a combination of: UV exposure : Queensland’s sun is brutal. Over time, UV rays break down the chemical bonds in roof paint, causing it to fade and flake. Poor preparation : If a roof wasn’t cleaned or primed properly before painting, the coating won’t bond — leading to early peeling. Inferior products : Some paints simply aren’t made for metal surfaces or don’t have UV protection. Moisture or rust under the surface : If rust wasn’t treated before painting, it keeps spreading beneath the coating. Signs Your Roof Paint Is More Than Cosmetic Patchy or streaky roof surfaces Rust spots beginning to show through paint Flakes in your gutters Water pooling around screws or seams These aren’t just visual issues. Left untreated, peeling paint leads to rust, weakened structural integrity, and eventually leaks. The Right Way to Fix a Peeling Metal Roof Quick fix paint jobs don’t last. Repainting a peeling roof without fixing the root causes is like putting new wallpaper on a crumbling wall. At JMZ Roof Restorations, we follow a professional, step-by-step process: Inspection : We identify all problem areas, including rust, water entry points, and coating failures. High-pressure cleaning : We remove dirt, chalk, mould and loose paint thoroughly. Rust treatment : We apply inhibitors where rust is active. Priming : Using purpose-designed primers for metal adhesion. Application of Roofcote : A flexible, UV-resistant membrane engineered for Queensland conditions. This isn’t just repainting — it’s metal roof restoration done right. How Long Will It Last? With the right prep and product, a restored metal roof can last 10–12 years before needing another coat. Cheaper options may start peeling again in 2–3 years — and cost you more long term. Why Roofcote Works Better Not all roof coatings are equal.
