Additional Brisbane roof replacement cost
As you might imagine, the process of roof replacement cost is going to vary widely depending on several factors, especially if you’re considering metal roofing. These are some considerations to keep in mind.
Complexity and size of your roof design
One of the most obvious factors is, how many square metres is your roof? The average size of a roof in Australia is between approximately 150 and 200 square metres. A smaller roof of around 100 square metres will save you some funds, while a bigger roof will increase prices. When considering roof replacement cost, the size of your roof plays a significant role in the final amount.
Your roof’s design is also significant. Simple roofs are less labour-intensive and quicker to complete, particularly with metal roofing. This will help you save on the workmanship. More complicated roofs with multiple angles pose extra challenges.
A roof with multiple separate surfaces and tricky design elements, such as a hip and valley roof, will extend the work time. It also requires additional work on replacing flashing around roof ventilation, gutters, and other features, all of which can add to your overall roof replacement cost, especially if you’re considering metal roofing.
Old roofing materials
It’s one thing if you are looking to replace your existing roof materials with the same product. However, many homeowners want to switch to a different material when getting a new roof. A roof replacement project is the perfect time to consider changing, after all. In these cases, it should be remembered that roofing materials have different weights per square metre.
If you’re changing from a metal roofing to concrete roof tiles, you’ll be adding considerable weight. If there are concerns around structural integrity, your roof structure will need greater reinforcement. Alternatively, if you’re switching to a lighter-weight material, you may think that there shouldn’t be any issues. However, heavier roofs can withstand uplift from heavy winds easier.
When getting a lighter roof, such as during a roof replacement project or when switching to slate roofing, a professional roofing contractor ensures that you’ll have sufficient tie-downs to prevent costly repairs in the future.
A new material may also require roof insulation work. Metal roofing effectively reflects heat, while terracotta tiles retain heat well. Depending on your locale, it’s worth considering whether insulation is a factor to maximise your energy efficiency, as this can also impact your overall roofing costs.
Asbestos roof
There are still many houses in Queensland that contain asbestos. Legislation and local building codes govern the asbestos waste removal process. Asbestos can either be non-friable, where the asbestos is bound in the matrix of another material, or friable, which means it crumbles easily.
If you’re replacing an asbestos roof with metal roofing, special care and compliance are required during the removal and installation process, especially when considering the roof pitch. It’s essential to work with reputable contractors to ensure all safety and legal requirements are met.
10 square metres of non-friable asbestos roofing can be removed without a special license. However, beyond that requires someone licensed in asbestos removal. The delicate nature of this work requires removalists to follow strict safety protocols related to your current roof.
The need for the roofing professional to hold the appropriate roofing licences will increase overall costs. When considering Brisbane roofing projects, several factors, such as licensing, safety requirements, and the type of roof, will influence the final price.

Conclusion
Roof replacement is a significant investment. The average costs encompass the roofing materials and labour needed. Premium materials and quality workmanship will cost more upfront but provide long-term durability.
The project’s complexity, such as a steep roof pitch, and the need to avoid structural damage by using different roofing materials are factors. The handling of dangerous roofing materials like asbestos requires specialised licensing, which will cost more.
