A roof can be considered a good one if it can last long and withstand all natural disasters. But as the years pass and climate changes, the roof’s requirement massively changes as well.
Aside from durability and protection, a good roof must meet the following:
- Provide comfort even under the extreme heat of summer or the cold of winter;
- Be effective in energy conservation;
- And can boost the home’s overall value (appearance and market value).
Don’t worry, this is easily achievable by installing insulated roofing panels. So whether you are building your home from the ground up or replacing the roof due to damages, it’s recommended to choose the right insulated roofing panels for your roof.
Choosing The Right Insulated Roofing Panels
1. Determine the R-value
Upon working on the roof, the first thing that every professional roofer will determine is the R-value. A quick fact: R-value is the insulating material’s capacity to withstand heat flow.
Professional roofers recommend choosing a higher R-value as this is known to have better insulating power. Here, in Australia, the factors that help you determine the accurate R-value is the house type and the climate zone per State.
2. Meet the law requirements
After determining the R-value, the next to check is the requirement set by the Local Council and Building Code of Australia (BCA). These requirements are covered by individual regulations designed for different purposes.
The regulations for insulations are for the following purposes:
- The R-value appropriate for the climate zone per State and house type
- The level of insulation needed per parts of the house
- The assessment and test required for the materials or per process
- The permits needed to obtain before performing a job
- The materials that insulated roofing panels use are fire-resistant or treated to be non-combustible
The regulations included on the BCA and Local Council can be confusing at times. To prevent this from happening, it’s wise to consult a professional roofer. They can explain each regulation clearly.

3. Consider insulated ceiling panels
A good understanding of the products is always a good advantage. This will give the consumer an idea on which option is the best.
The common choice of roof insulation is the insulated roofing panels. Though it is proven to be effective, it is still wise to consider other options such as insulated ceiling panels.
The insulated ceiling panels are commonly used if the homeowner doesn’t want to install bulky insulation on the roof. This is much easier and quicker to install compared to insulated roofing panels. But in terms of efficiency, they are both compliant with the BCA regulation (e.g. AS/NZS 4859.1) and effective in minimising heat transfer, condensation and mould growth.
Can’t decide what to choose? It’s all right, homeowners always have the option to install both the insulated ceiling panels and insulated roofing panels. Consult a trusted roofer to ensure if the Local Council permits this on your location.
4. Pick the right thickness of insulated roofing panels
The sizes of insulated roofing panels range from 50mm up to 150mm. It is said that the thicker the insulated roofing panels are, the better its insulating capacity will be. Though this is true, most States include standard sized insulated roofing panels on their requirements.
If it doesn’t mention anything, it’s wise to consult a professional roofer. A qualified roofer knows all the factors to consider in determining the right size of insulated panels. Few of the factors are the total amount of insulation the house needed, location’s wind rating, and more.
Roofing plays a vital role in the house. But it can also cause the biggest safety risk. To avoid costly re-dos or worse, facing accident-related injuries, let a professional roofer do the job.
