Choosing the Right Paint for Your Australian Roof

What factors to consider when choosing your roof paint and how to make sure you have covered all your bases

The weather in Australia can be quite harsh on rooftops at times. A great example would be the extreme weather patterns that Sydney experiences fairly regularly including conditions such as acidic breeze, hailstorms, torrential rains and heatwaves. For that reason, it makes sense that choosing the right materials is essential to maintain your house’s structure and appearance, and that definitely includes roof paint!

Roof painting involves many more considerations than just choosing a new look or style for your home and If you’re at a loss on where to start, here are some tips to guide you through the process of selecting the right roof paint for your home

Check the material of your roof

Roofs are made from different materials, and the most common materials are concrete, colourbond and corrugated iron or metal. It’s important that you know what the type of roof you have is because it may not be compatible with the paint you choose.

·   Concrete Tile Roofs

Concrete tiles on roofs do not necessarily need painting for structural reasons, however it’s certainly done now and then - especially during remodelling or for styling reasons. It requires a clear alkyd primer to form an acceptable bond between the surface of the tile and the new coating. We recommend using a high-quality 100% acrylic paint afterwards to finish the job.

·   Colorbond roof

Painting a colorbond roof is not as easy as painting concrete tile roofs. The process is entirely different, and a multi-layer coating system is needed to produce a sleek and long-lasting finish.

Some colorbond roof paints are self-priming, but you can still use a primer to make sure that the application of paint is even just to be extra sure. Using an airless spray gun can help for better adhesion and smooth application of the primer.

Colorbond roof paints are made out of a specialised water-based acrylic membrane, which can only be applied using an airless spray gun for an even finish. It needs at least two coats before allowing it to sit properly.

·   Corrugated iron and metal roof

Don’t just choose any paint for a corrugated iron and metal roof. Instead, look for an acrylic-based paint for “exterior use”. In addition, acrylic latex paint functions well, especially if the roof is relatively brand new and not suffering from wear and tear.

You can also use oil-based alkyd paint and pair it with a suitable galvanised metal primer. However, a topcoat does not remove the need for a primer. The topcoat will secure the paint, but the primer will make the paint adhere effectively.

Stay away from lead

No matter the case, always stay away from paints that contain lead as their main component. Lead-based paints are not allowed in many areas and they also pose health hazards for you and your family.

Exposure to high amounts of lead may result in weakness, anaemia, and brain and kidney damage. Lead can also cross the placental barrier, so if a pregnant woman in your family is exposed, her unborn child becomes at risk. Safer choices include titanium dioxide and acrylic paint.

Consider the type of protection you want for your roof

There are now many innovative roof paints available on the market that address the various concerns of homeowners. Try to narrow down what kind of protection you want for your roof to help in the process of choosing the type of paint you want.

  • Climate change caused an increase in temperature in many parts of the world. Added to this fact is that Australia is one of the countries that receive the most sunlight every year.
  • If you want to control the heat and the costs for air-conditioning, a heat-reflective roof paint might be a good idea. The paint has the ability to eliminate solar heat even before it enters your home. It will also protect your roof from corrosion and thermal shock. A heat reflective roof also increases the value of your house.
  • If you’re in the part of Sydney that experiences hailstorms and heavy rains, a waterproofing paint might work for you. There are different types of waterproofing paints, the most common of which is Masonry paint and acrylic paint.

Masonry paint can be used for almost all types of roof. It also quickly absorbs liquid solutions such as chemicals and water, and does not allow rainwater to penetrate your roof which makes it durable and dirt-resistant as well.

On the other hand, using acrylic paint with a primer increases your roof’s resistance to water. It is non-toxic, odour-free and quick drying.

  • If corrosion is a concern, look for a paint that works well with a primer that has anti-corrosive properties.
  • Some paints also offer other benefits like fire resistance or ability to repel pests and insects. With so many options available, choose the paint which makes sense for your needs.

Take time in selecting the colour of your roof paint

It’s easy to get too excited about choosing the colours for your chosen roof paint and overlook the functional factors that need to be thought about! There are other things you need to take into consideration when it comes to roof colour such as:

  • The colour of your roof can change the temperature of your attic by 20-40 degrees. It will have a massive impact on the cooling or heating costs of your home.

Light colours deflect sunlight and help keep the temperature low in a hot climate. On the other hand, dark colours absorb heat and help you to stay warm in cold a climate.

  • You might also want to check how your roof colour will affect the overall look of your home. For instance, a black or dark grey would likely match well with a blue or grey house. A brown roof goes well with a tan, cream or brown-coloured house. Dark colours can also make your house look smaller, while light colours do the opposite.
