Stay Cooler This Summer with Your Roof!

Undeniably, climate change is leading to hotter summers, tempting us to stay indoors, cooling off under fans and air conditioners as the temperature soars. But did you know that your roof can significantly influence your home’s interior temperature?

If you’re aiming to stay cool during the sweltering summer months, it’s essential to make sure your roof is equipped to help.

The New-Age Cooler Roof

Modern cooler roofs use highly reflective paint, tiles, shingles or coatings designed to deflect the sun’s harsh rays, absorbing less heat than traditional roofs. They make your home’s interior more comfortable during heatwaves and save significantly on energy costs.

The Working of Cool Roofs

Cool roofs work on the same principle as wearing light-coloured clothing on a warm day or choosing light-coloured paints for your home’s exterior. They reflect heat, meaning the structure absorbs fewer sun’s rays.

Your roof’s colour dramatically impacts maintaining a comfortable temperature inside your home. The lighter the shade of your roof, the more light it reflects, and the less heat it absorbs. Darker roofs allow heat absorption into your eaves and attic space, which then transfers to the rooms below.

In fact, a lighter coloured roof can reduce absorbed heat by up to 10 degrees Celsius. So, a scorching 40+ degree day can drop to a much more comfortable 30+ degrees, just by changing your roof’s colour!

Benefits of Cool Roofs:

  • Lower Energy Bills: Reducing your interior temperature eases the strain on air conditioners, leading to long-term savings.
  • Greater Thermal Comfort: With more summer days above 40 degrees Celsius, it’s sensible to find ways to improve indoor temperatures.
  • Protect Your Investment: Lowering the temperature your roof absorbs can extend its lifespan, reducing the need for repairs and saving money in the long term.
  • Reduce Moisture: Homes in tropical climates suffering from rising damp and mould can also benefit from roofs coated with mould and algae retardant chemicals, extending their structure’s life.
  • Environmental Impact: Cool roofs can reduce overall air temperatures, especially in built-up areas. Lower usage of air conditioning and fans cuts down on potential power blackouts due to high peak electricity demand and reduces emissions, combating climate change.

Can You Retrofit a Cooler Roof?

The best time to consider installing a cool roof is when you’re building a new home. However, you can retrofit your existing roof. If your roof is nearing the end of its lifecycle, recovering or replacing it with smarter, cooling roof materials is a good choice. But if your roof is still in excellent condition, recoating it with specialised heat and light-reflective materials can also be beneficial.
