Yes, your roof can keep your home cooler this summer!

Roof Restoration in Brisbane & Gold Coast


Climate change is undoubtedly contributing to hotter summers, and that means we're more likely to wait out 40+ degrees Celsius indoors in front of fans and air conditioners as the mercury rises through the roof – literally!


Because – did you know – the kind of roof you have can play a significant role in the temperature of your home’s interior?


If you want to keep your cool during the summer months (and, conversely, warm your home in winter), it pays to ensure your roof is as cool as it can be.


The new cooler roof.

New age cool roofs use highly reflective paint, tiles, shingles, coverings or coatings designed to deflect the sun's harsh rays and absorb less heat than traditional roofs. They can make your interior more comfortable during heatwaves and save you big time on energy costs, too.


How cool roofs work.

Cool roofs work on the same principle as wearing lighter coloured clothing when its warm, choosing light coloured paints for the exterior of your home or adding cool coloured blinds on wide windows – all reflect heat, so the structure absorbs fewer of the sun's rays.


Your roof's colour makes a big difference when it comes to maintaining a constant, comfortable temperature inside. Essentially, the lighter the shade of your roof, the more light it reflects and the less heat it absorbs. Darker coloured rooftops allow heat to be absorbed into your eaves and attic space, which then gets transferred into the rooms below.


In fact, a lighter coloured roof can dramatically reduce absorbed heat by up to 10 degrees Celsius – so a 40+ degree day can be reduced to a much more comfortable 30+ degrees – just by changing the colour of your roof!


Cool rooves – the benefits:


  • Reduce your energy bills – dropping your interior temperature by 10 degrees takes the pressure off air conditioners so you’ll save more in the long run.
  • Greater thermal comfort on stinking hot days – with more summer days above 40 degrees Celsius, it makes sense to find simple ways to improve indoor temperatures as much as possible.
  • Protect your investment – decreasing the temperature your roof absorbs can extend its life and ensure your roof lasts longer without the need for repairs (again saving you money over the long term)
  • Reduce moisture – homes in tropical or subtropical climates that suffer from rising damp and mould can also have their roofs coated in mould and algae retardant chemicals that will further extend the life of their structure.
  • Do your bit to help save the environment – cool roofs can reduce overall air temperatures, especially in built-up areas where the urban heat island effect can create a bubble of hot air. Lowering your air conditioner and fan usage in the summer months cuts down on potential power blackouts due to high peak electricity demand. Using less power also helps reduce emissions, which in turn helps to combat climate change.


Can you retrofit a cooler roof?

The best time to seriously consider installing a cool roof is when you're building a new home. However, you can retrofit your roof to be more flexible in our modern, far hotter environment. If your roof is already nearing the end of its life cycle, you can recover or replace it with one of the new, smarter, more cooling roof materials. But if your roof is still in excellent condition, recoating it with specialised heat and light-reflective materials can also be useful.
