How much does it cost to repair a roof in Australia [2024]

If your roof is damaged or needs repairs, it’s vital that you hire a professional tradie to help fix the issue and keep your property – whether it’s a home or business – protected against the elements. To help you calculate the cost of hiring someone to repair your roof, here’s what you need to know.

How much does it cost to repair a roof?

Roof repair specialists may charge by the hour or per square metre. Hourly rates can be anywhere from $40 to $90 per hour or more, and this rate doesn't give the best indicator of your total roof repair cost.

A square-metre roof repair quote can be more accurate, which can cost anywhere from $15 to $35 per sqm on average. However, the price per square metre will vary depending on a number of factors such as:

• The type of roofing material that needs repairing
• The quality of the roofing materials used in making a repair
• The difficulty or ease of access to the roof
• The roof's pitch and/or complexity
• The expertise of the roof repair service
• The type of repair being carried out (e.g. repointing or roof leak repair)

What are the factors that affect the cost of roof repairs?

Roof repairs can vary significantly in cost based on several factors. Understanding these factors can help you build an appropriate budget and make better decisions around who to hire. Here are some factors that tend to influence the cost of roof repairs:

1. Roof type: Asphalt shingles are generally the least expensive for tradies to work with, while slate and tile shingles can be more costly. Metal roofs tend to be higher on the price spectrum as well.
2. Repair permits: Permits may be required for certain roof repairs, and how much they cost will depend on where you are located and the size or value of your property. Some coastal areas may have additional permits for flooding protection (or cyclone risks, such as in North Queensland), which can increase the overall cost.
3. Scope of repairs: The size of the repair area, measured in square footage, affects the cost. Roofing contractors will charge based on the square footage, even if the repair area is smaller.
4. Existing water damage: Undetected water damage can lead to more extensive repairs or even a complete roof replacement.
5. Chimney and skylights: Chimneys, skylights and other rooftop elements may require specialised professionals to handle repairs or replacements. Hiring these tradies will inevitably add to your labour costs.
6. Leaks: The number and severity of leaks in your roof (if any) will affect the materials required and time spent working on repairs. More leaks and extensive damage will of course result in higher costs.
7. Roof design: Steep roofs or complex designs require more effort and time to complete repairs, increasing the overall cost. The height and accessibility of your house also influences the complexity of the job.
8. Time of year: Repairing a roof during freezing temperatures or heavy rains will be more challenging – and therefore more dangerous and costly.

Scheduling repairs during the off-season when demand is lower may mean you get a discounted rate. Remember to get quotes from a few different roofers and beware of low estimates.

What is the cost of roof repair by material?

If any roofing needs to be replaced, the material it's made from will have a big impact on the roof repair cost. For example:

• Tile roofing costs between $40 to $80 per sqm, according to Vertec Roofing.
• Colorbond roof sheets price can be between $13 and $37 per sheet.
• High-quality corrugated roofing iron prices can be between $50 and $70 per sqm.

Roof repair cost by size

While a larger roof will cost more, the roof repair cost per square metre decreases for larger projects. Smaller jobs have a higher rate to compensate for travel and set-up time. Total roof repair cost and restoration can be:

• 100–150 sqm: $3,000–$4,700
• 150–200 sqm: $4,700–$6,300
• 200–250 sqm: $6,300–$9,400
• 250–300 sqm: $9,400–$12,500

Roof repair cost by service

Minor roof leak repair costs will be different from replacing broken tiles. For example:

• Minor repairs: $1,000
• Replacing gutters: $1,200
• Replacing roof tiles: $1,300
• Repairing ridge caps: $2,000
• Replacing mortar: $2,500

Why is it important to repair a roof ASAP?

Repairing a roof as soon as possible helps prevent further damage that can occur as a result of leaks or a totally compromised roof. Water leaks can lead to extensive structural deterioration and mould growth. So addressing the problem promptly means you can prevent these issues from spreading to other areas of your property.0

A timely roof repair is also essential for protecting your belongings. Water leaks can damage furniture, electronics and personal items very quickly. The alternative is cutting into your savings to replace expensive possessions.

Energy efficiency is another concern for roof repairs. If your roof is damaged, it can compromise the insulation, leading to rapid heat or cool-air loss. This places additional strain on your HVAC system and increases energy bills.

Last but certainly not least, a damaged roof poses safety risks. Whether it's the potential for a roof collapse or hazards like loose shingles, addressing repairs in a timely manner means you can rest easy knowing your home and family are safe.
