Heat reflective roof paint: Does it work?


Heat reflective roof paint: Does it work?

Jun 27, 2023

Are you worried about your rising energy bills? Is the scorching sun hindering your day-to-day activities? Are you looking for an effective and permanent solution to all these problems? If yes, then heat-reflective roof paint is the one-stop solution for you! 

There has been a growing concern for climate change and global warming in the past few years. Further, numerous factors have led people to understand the importance of evaluating energy consumption and energy efficiency. As such, going "green" and "saving energy" has become a common approach for many homeowners. With increasing energy costs, saving energy is essential more than ever now. 

People have to insulate their homes and keep the heat in to survive during freezing winters. On the other hand, keeping the house cool during scorching summers is important too.

The roof is the major contributing factor to the heating capabilities of any building. Be it the roof material or the colour, both factors can significantly impact your heating or cooling spending. 

Here’s where heat-reflective roof paint comes into the role!  With a number of advantages this revolutionary product offers, it has taken the paint industry by storm. From keeping your roof and house cool to enhanced comfort and cost-efficiency, heat-reflective roof paint is worth it. 

Let’s learn more about why heat-reflective paints are the best for house roof painting.  

What Is Heat Reflective Roof Paint?

It is a modern-day paint that comes with the ability to reflect the sun’s radiation. Such paints prevent the sun’s heat from entering the house while pulling out excessive heat. This helps the building with improved insulation. 

In simple words, heat-reflective paint cools down your roof. It usually comes in white or light-coloured hues and boosts better insulation for your building. Whether you have a colourbond roof like terracotta roof paint or a metal roof, the heat-reflective coating is suitable for all roof types.  

Here are some statistics about the usage of heat-reflective roof paint you should consider:

  • Heat-reflective paint can save you up to 40% on your energy bill and decrease your overall energy consumption by 25%.
  • Heat-reflective paint can decrease a roof's temperature by as much as 60 degrees C.
  • Estimates suggest that the typical Australian household can reduce the amount of carbon dioxide they produce by 18 tonnes by using heat-reflective roof paint.

How Does Heat Reflective Roof Paint Work?

To understand the working of heat-reflective roof paints, you must first know how solar energy interacts with life on Earth. As known, the sun is a major energy source and emits both visible and invisible solar radiation.

The bright and warm sunlight you see is visible radiation, while infrared and ultraviolet rays are invisible. With the sun shining, everything around reflects or absorbs the solar radiation it emits. 

When things take in light and heat from the sun, they usually release warmth or reflect a bright colour. This is why you can feel the hot temperature and see the bright light coming from objects nearby.

Here’s where heat-reflective roof paint comes into effect. It can help keep your building cooler by blocking the sun's heat from entering the roof. It works like a mirror, reflecting the sun's rays away and preventing the building from getting too hot. This can make the inside of the building more comfortable.

But are all heat-reflective roof paints reliable? How to know which is the right roof paint for your home or office building?

Things To Consider When Choosing A Heat-Reflective Roof Paint

Here are some important things to consider when selecting heat-reflective roof paint:


The primary purpose of heat-reflective roof paint is to reflect the sun's heat away from the building. Look for a paint with a high Solar Reflectance Index (SRI) rating. It is a measure of the paint's ability to reflect solar energy.


Roof paints are exposed to harsh weather conditions and UV radiation. Hence, choosing a durable product that can withstand these conditions without fading, cracking, or peeling is essential.


Choosing a light-coloured heat-reflective roof paint that can reflect more sunlight than a darker shade is essential. White or light-coloured paints are highly reflective and help keep the building cooler.

Brand Reputation

Take notice of the reputation of the brand before purchasing heat-reflective roof paint. A reputable brand will offer a high-quality product that meets industry standards. The best way is to look for a brand with the Energy Star Logo. 

Energy Star is a well-known brand that many certifiers, builders, and architects use to ensure their work is high quality. Energy Star's heat-reflective roof paint is the only coating certified by the Code Mark. It also meets the rules set by the Building Code of Australia.


The cost of the paint is an essential factor to consider. While cheaper options may seem appealing, they may not offer the same level of durability and reflectivity as expensive paints. It's important to maintain a balance between cost and quality.

Environmental Impact

Look for a paint that is environmentally friendly and does not contain harmful chemicals or volatile organic compounds (VOCs). Choosing an eco-friendly option can help minimise your carbon footprint and promote sustainability.

Benefits of Heat Reflective Roof Paint

Here’s how applying heat-reflective coating on your roofs can benefit you:

Energy Efficiency

One of the biggest benefits of heat-reflective roof paint is that it can significantly cut down the energy requirements to cool a building. By reflecting the sun's rays, the roof stays cooler. This means less heat is transferred to the interior of the building. This minimises the need for air conditioning and can result in significant energy savings.

Increased Comfort & Aesthetics

Buildings with heat-reflective roof paint are generally more comfortable. That’s because the temperature inside is more stable, and the air conditioning system doesn't have to work as hard. This can lead to increased productivity and happier occupants. Plus, the bright-coloured hues increase the aesthetics or looks of your property. 

Longer Roof Life

The heat-reflective coating can also extend the life of a roof. Reducing the amount of heat the roof absorbs allows the paint to prevent damage caused by extreme temperatures. This can result in less frequent repairs and roof replacements, saving you money in the long run.

Environmental Benefits

Buildings with heat-reflective roof paint require less energy to cool. This means they have a lower carbon footprint. By reducing energy consumption, buildings with heat-reflective roof paint can help reduce greenhouse gas emissions. They can contribute to a more sustainable future.


The heat reflective coating is a cost-effective way to improve a building’s energy efficiency. While the initial investment may be slightly higher than traditional roof paint, the energy savings over time can result in significant cost savings. Additionally, the longer lifespan of the roof means that building owners will spend less money on repairs and replacements. Further, it also increases the resale value of your home. 

The Final Say

Considering the growing impact of climate change, it’s important now to choose more sustainable and energy-efficient housing materials. Heat-reflective paint is a special roof coating that can reflect solar radiation. This leads to improvement in the insulation of your building. 

Heat-reflective roof paint offers numerous benefits, including heat shock and corrosion protection, a longer-lasting roof, and a cooler roof.

Further, this paint type is a sustainable option for environmentally conscious people as it significantly lowers a home’s carbon dioxide emission level.
