The cost of roof replacement depends on a number of factors, including the size and layout of your roof and the roofing materials used.
The four main considerations that will affect the cost of replacing your roof include:
1. The type of roofing material you choose
The most common materials used in roofing are:
With industry leader Colorbond offering flexible roofing solutions built to withstand the varying weather conditions across Australia, metal roofing provides strength, stability, and durability.
With energy and money-saving benefits, Colorbond steel is a popular choice when it comes to roof replacement.
Available in slate, terracotta, or concrete, tiled roofing may take a larger chunk out of your budget, however, these materials offer a significantly longer lifespan than metal roofing.
If you are replacing a metal roof with this type of roofing, your home may require some additional structural work to accommodate the heavier materials.
2. The size of your roof
The cost of roofing is priced per square metre (m2). Therefore, the size of your roof and the materials you choose will directly impact how much you pay:
$18 to $37 per m2
$40 to $60 per m2
$80 to $130 per m2
$200 to $500 per m2
3. The layout/design of your roof
There are a number of different types of roofing designs that determine whether the replacement process will be relatively easy or more complex.
A skillion roof, for example, usually has one flat surface with a slight pitch for water runoff. This type of roof is comparably straightforward to replace than a curved or hipped roof which is more complicated in design and therefore more costly to replace.
4. Labour charges
A major part of replacing your roof is the removal and disposal of your existing roofing material. The associated labour costs will vary depending on the type of roofing you have, with asbestos removal increasing costs considerably due to safety requirements.
Ease of access to your roof and any necessary structural repairs will also affect the overall costs of roof replacement.
