Choosing roofing is an important decision, especially in Australia. Colorbond roofs are a smart option. They’re not only durable but also energy efficient. Unlike other roofs, colorbonding also adds style and sophistication to your home’s exterior.
When it comes to choosing a roof, sarking is essential. It provides an additional layer of insulation, serving as a vapour barrier in varying temperatures. Even though Colorbond roofs are already highly durable, including sarking is still necessary.
Here’s why.
What is roof sarking?
Sarking is a layer of material on your roof. It sits beneath the roofing material and in between the roof deck and panels like tiles or metal sheets. It basically provides a protective second skin for your roof cavity. It also acts as a form of roofing insulation. Sarking is made of reflective foil or fibreglass to reduce your cooling costs.
The pros of roof sarking for metal roofs
If you’re still unsure whether you need sarking for your roofing system, here are the pros.
Sarking improves moisture control
Roof sarking serves as an additional shield to keep water out. This is especially useful in the rainstorm season in Australia. By stopping moisture from entering the roof area it lowers the chance of water-related harm to the roof and insulation. This is crucial for metal roofs that are susceptible to condensation problems.
Boosts thermal insulation
Sarking improves thermal insulation by reflecting heat away from the building. This keeps interiors cooler during hot Australian summers to improve how comfortable your home feels. It also reduces energy consumption and cooling costs.
Prevents dust and dirt
Roof sarking acts as a great shield against dust and dirt. It proves especially beneficial for metal roofs that tend to have openings where debris could get in, as sarking helps keep the roof space cleaner. This is especially handy in regions susceptible to strong winds and dusty conditions.
Improves fire protection
In regions prone to wildfires, roof sarking is crucial for improving fire safety. It provides essential protection by guarding the roof space against embers and possible sources of ignition, which is particularly beneficial for metal roofs prevalent in fire-prone zones due to their nonflammable characteristics.
Reduces noise
You don’t want to hear heavy rain or hail in your home.
Roof sarking helps to dampen noise by providing an additional layer between the metal roof and the roof space. This can improve your comfort during intense weather.
Prolongs roof’s lifespan
Roofs cost thousands of dollars to replace. Improve its longevity by adding roof sarking.
It protects the roof structure from moisture and temperature fluctuations. This added layer serves to prevent rust and deterioration, ensuring the durability of the metal roofing material over time.
It’s more energy-efficient
Using sarking improves a home’s energy efficiency. It reflects heat and stops heat from entering the roof area. This helps maintain a consistent indoor temperature resulting in less dependence on air conditioning units and, as a result, lower energy costs.
What is colorbond roofing?
One of the most popular choices for Australian roofs, colorbonding can withstand intense weather conditions and improve a home’s thermal efficiency. Colorbond is a type of steel roof sheeting. It’s installed over the roof sheeting, acting as its outer layer.
Is roof sarking required for colorbond roofs?
In Australian territories prone to wildfires, roof sarking combined with colorbond roofing material may be required for added protection and to comply with building code bushfire attack level (BAL). From a practical standpoint, sarking can improve the performance and longevity of your roofing system. So, while it might not be legally required in your state or territory, installing sarking is necessary.
Pros of installing roof sarking with a colorbond metal roof
Roof sarking and colorbond roofs partner well together. Here’s why you should consider adding sarking during the installation process:
Colorbond metal panes, while very durable, are still susceptible to water leaks, especially during monsoon season. Roof sarking is an additional weatherproofing measure so you can enjoy a dry home during severe weather conditions.
Metal roofs are prone to condenstation issues, including colorbond. This can be particularly dangerous in Australia, thanks to humid climates. Roof sarking also manages condensation with its vapour barrier, stopping moisture from getting into ceiling spaces.
Metal panels on roofs are notoriously noisy when it’s rainy or windy. Roof sarking acts as a sound barrier, shielding your living space from outdoor sounds so you can enjoy a more peaceful existence.
How much does roof sarking cost?
The cost of roof sarking depends on the type you buy and how heavy the duty is. Your home’s thermal rating will also affect how much you’ll pay. Costs normally start at around $2 per square metre, so an average roll is approximately $75.
You’ll also need to pay professionals to install the roof sarking for you. Because it is normally installed with the rest of your roofing system, you’ll probably need to pay your roofers an additional fee.
