Cost-effective roofing solution that withstands the Australian climate
Does your property – or a property you’re working on – need a new roofing solution that is ideal for drier climates and made with natural materials? If so, a thatched roof could be your ideal solution. Thatched roofing uses dry vegetation to steer water away from the inner roof and, when properly maintained, offers many aesthetic and functional benefits.
Not only is it versatile enough to look great on a wide range of building styles, but it also lasts up to 30 + years when well maintained. It provides excellent insulation, energy efficiency, and protection from the elements. Thatch roofing has stood the test of time as a popular solution for any structure with a roof, giving it historical significance.
The question on many prospective buyers’ minds is, how long does thatched roofing last?
While every property owner wants their investment to last, several factors affect the life expectancy of a thatched roof, from the weather conditions to the materials used and the quality of craftsmanship.
Let’s explore the main factors that affect thatched roof lifespan and strategies for getting the most out of your investment.
Understanding thatched roofing
In simple terms, a thatched roof consists of layers of dried vegetation. This roofing option dates back to 1800 BC and was originally used as a temporary shelter for travelling nomads. It then spread to the British Isles, where thatched cottages date back to the 16th century. Still in use today across various applications. Although generally not a suitable solution for a residential roof due to Australian Building Codes, this roofing style stands strong as a solution for huts, resorts, gazebos, saunas and more.
Island Thatch supplies the two most popular and cost-effective options, Bali and African Thatch Roofing, alongside synthetic options made from Virothatch and One Thatch. While there are other thatching materials, such as water reed, combed wheat reed, and straw; these are more expensive and difficult to harvest sustainably. The materials we use at Island Thatch each have unique properties that add character, protect against environmental factors and ultimately contribute to their popularity.
The lifespan of a thatched roof
General longevity expectations
Conventional roofing materials, by comparison, may last between 25 and 50 years, depending on the materials used. They are comparatively expensive and require a great deal of maintenance. The average lifespan of Bali and African thatched roofs ranges between 10 and 20 years, and our prices start from $500, depending on the size and complexity of your application. Thatched roofing is a cheap alternative that saves on repair and replacement costs in the long term.
Despite the predicted shorter lifespan, there are many ways to keep a natural thatch roof in good condition and maximise value for money.
Factors influencing longevity
Several factors influence thatched roof lifespan.
- Environmental conditions. Leaf debris, and overhanging branches can affect the longevity of a thatched roof structure. Bali and African Thatching are built to withstand the harsh Australian climate.
- Expertise in installation. The skill of the thatcher is another key to ensuring a properly installed structure and, ultimately, a long life for your new thatched roof.
- Regular maintenance practices. How long does a thatched roof last? The answer depends largely on the maintenance carried out after installation. Although not much maintenance is required, a little attention here and there goes a long way to increase its longevity.
Maintenance tips for prolonging thatched roof lifespan
Regular inspections and repairs
Generally speaking, periodic inspections are key to making a thatched roof last as long as possible and preventing any existing issues from worsening.
Let’s explore a few factors that commonly affect thatched roofing materials and can lead to a shorter lifespan.
Rotting
The angle of a thatched roof lends itself to runoff, meaning water will only penetrate the top layer. However, prolonged dampness can cause thatch to rot. The best way to prevent this is to keep the roof clear of debris and ensure a higher-pitch roof where possible.
Moss and debris
A buildup of moss and debris on top of a thatched roof contributes to mould growth, damaging the roof structure. Again, the best way to prevent this is to clear the top of the roof of debris regularly.
Thinning
Thinning occurs naturally over time, whether due to damage or regular wear and tear. The best way to manage this is to check the roof regularly for signs of damage and contact a professional roofer if you notice the condition worsening.
Preservation techniques
Using the right preservation techniques is crucial for maximising the overall lifespan of a thatched roof. Island Thatch offers a high-quality product preservation range that is ideal for preserving popular thatched roof materials. From thatched to timber and bamboo coatings, we have a product to suit all your natural materials.

Cost considerations
Initial costs vs. long-term benefits
The cost of installing a thatched roof can vary significantly, starting from $500, depending on the natural thatch material used and the complexity and size of your application. Long-term savings can be achieved through the low installation cost and its low maintenance design.
Budgeting for maintenance
All roof types require some maintenance over time, and it’s important to factor these costs into your budget. The better the condition of a thatched roof, the lower the maintenance bills will be. While some maintenance tasks are best done by a professional, simply keeping the roof dry by clearing plants and trees will make a big difference.
