Keeping your home ventilated is crucial for stopping the spread of mould and damp – which starts with a well-maintained roof. Properly sealed roofs also ensure thorough protection, therefore improving energy efficiency and creating a comfortable living environment for your family.
However, from the size of your home to the extent of the damage, several factors can impact how much you’ll pay for a quality roof repair job in Australia. Understanding these factors can be incredibly useful when comparing contractor quotes and choosing a cost-effective deal that fits into your budget.
Whether you require a few simple tile replacements or major repointing, discover the average roof repair cost for your home.
What Are the Average Roof Repair Costs in Australia?
Whether you require some small repairs or a complete roof replacement, the national average roof repair cost ranges from $15 to $35 per square metre.
The most accurate way to estimate your roof repair costs is by square-metre, as this considers the amount of material needed to cover the size of your home. However, roofing contractors may instead charge an hourly rate of $40 to $90, although this can vary depending on their professional expertise level, plus the size of the job and your location.
Key Factors Affecting Your Roof Repair Cost
Type of Roofing Material Used
Asphalt shingles are among the cheapest and most popular roofing materials to repair, while slate or metal roofs can be more expensive.
Roof leak repair costs are also lower than fixing broken tiles, as you’ll have to pay for roofing tar or bitumen rather than a full set of replacement tiles.
Roof Design and Features
Intricate design features such as skylights, chimneys, roof flashing, or vents can increase the average roof repair cost for your home.
Steep roofs are also harder for contractors to navigate and require special safety equipment such as harnesses, making them more expensive to repair than flatter roof types.
Severity of the Roof Damage
Small roof leaks or basic roof maintenance jobs like fixing your gutters tend to cost less than a full restoration or tile replacement. Any undetected water damage may also require a complete roof replacement, which can be expensive particularly if damp or mould are detected.
Expertise of the Roof Replacement Service
Experienced roofers often charge more for labour as they produce a higher-quality end result, using specialised equipment like shovels for removing old asphalt shingles, tin snips, power tools, and safety harnesses
They also have the expertise to advise you on reducing your roof repair cost in the future with more durable, long-term solutions, such as a watertight dry fixed roofing system.
Time and Location
The average cost for roof repairs tends to increase during the peak spring or summer months when our weather provides more suitable working conditions for contractors. Material prices and labour prices also vary depending on the region, especially in areas like North Queensland where flooding or cyclone protection permits are required for repairs.
Roof Repair Cost by Size
Expect to spend anything from $9,400 to $12,500 for larger roofs sized between 250 and 300 square metres, which require more time to complete. Based on size per square metre, complete restoration and roof repair jobs cost on average:
- 100 to 150: $3000 to $4,700
- 150 to 200: $4,600 to $6,300
- 200 to 250: $6,300 to $9,400
Although larger roof repairs take longer to complete, therefore increasing labour prices, the roof repair cost per square metre of material used is lower. Some companies may also charge a higher rate for smaller jobs, which compensate contractors for their travel and set-up time.
Extensive vs Minor Roof Repair Cost
For minor roof repairs, the average price of a gutter replacement is $1,000, or $30 to $160 per linear metre of guttering. A leaky roof repair cost is priced at around $28 to $38 for each square metre of patching required.
More complex jobs that involve handling delicate plumbing or electrical systems often cost as much as $12,500, depending on the extent of the roof damage and size of your home. Significant engineering or HVAC work also requires specialised equipment and materials, including repairing chimneys, fixing wiring, getting rid of mould, or addressing roof slumping.
Extensive roof repairs on older homes or a full roof replacement are generally priced between $5000 and $20,000 in Australia, depending on the type of tiling chosen.
Average Cost of Roof Repairs By Material
Tile replacements cost between $5 to $35 on average, but this varies depending on the materials used. For instance, durable concentre is the cheapest and most commonly used material as it creates the lightest tiles, while terracotta is a premium, higher-cost option.
Steel Colorbond roofing can be an expensive choice particularly if you opt for the Ultra material, which ensures longevity with three layers of protective coating. The average roof maintenance cost for Colorbond ranges from $13 to $37.
Corrugated iron sheets are another ideal, yet expensive choice for Australian homeowners at $50 to $70 per sheet as they’re built to withstand extreme weather conditions, including intense heat and heavy hail.
