Roof Replacement vs. Roof Restoration: What’s More Cost-Effective for Aging Roofs?


Roof replacement can be an expensive undertaking for homeowners, but it is a one-time investment that will guarantee the safety of a building and the capital worth of the house. Roof replacements may vary widely in cost, depending on the square footage of the roof, material, labour prices, and the complexity of the installation or project.
We at Action Roofing, carry out your roof replacement with premium materials and craftsmanship, knowing that the roof of your house is safe. Whether you are after a complete roof recovery or just want expert roofing advice, we are here to help you through every step of the process.Â
Understanding the Cost of Roof Replacement
The cost of replacing a roof is based on several factors, including:
Roof Size and Complexity
A larger roof requires more materials and labour, which increases the price, naturally. Also, the complexity of the roof design is fundamental. Roofs that have more than one slope or with valleys, dormers or penetrations like skylights and chimneys will be more complex and cost more in labour and materials to complete.
Material Choice
The roofing material chosen is directly related to the overall cost.  The characteristics of the materials determine their prices as some exhibit durability, beauty, and longevity. Colorbond Steel has been one of the most weather-resistant and durable materials of modern architecture. While terracotta tiles are appealing and durable, the cost of these will be quite a bit higher than other methods of flooring.  Concrete Tiles are a cheaper alternative than terracotta, used for durability and vintage appeal. Slate Roofing is an expensive, but very durable material. Asphalt Shingles are a budget-friendly option, though not as common in Australia as in other regions.
Labour Costs
The location, complexity of the installation project, and expertise level of the roofing personnel can create great differences in labour costs. If a skilled professional does the installation, the roof works properly, and there is less likelihood of problems down the line. Urban areas, where labour costs are higher, may result in more expensive roof replacement projects.
Removal of Old Roof
Removing the old roof adds to the total cost since it should be removed before a new roof is installed. Removing the roof means extra labour, extra disposal fees, and potentially temporary protective coverings.
Structural Repairs
Repairs need to be done if there are damages to the roofing, such as rotting timber battens or degrading insulation, and these will need to be repaired before the new roof is installed. The scope of these repairs can greatly affect the sale price.
Roof Pitch and Accessibility
Steep roof designs require more safety measures and equipment such as harnesses and Scaffolding to work safely. If the roof is difficult to reach, here is another factor that will add time, effort and inevitably cost.
Average Cost Estimates for Roof Replacement
Below is the approximate cost of roof replacement in Australia, depending on the material type:
Metal Roofing (Colorbond or Zincalume): $100 – $150 per square metre
Concrete Tile Roofing: $80 – $120 per square metre
Terracotta Tile Roofing: $120 – $180 per square metre
Slate Roofing: $200 – $500 per square metre
Asphalt Shingles: $50 – $80 per square metre
A complete roof replacement for a standard Australian house (with a 150m² roof area) might range from $15,000 to $30,000 in cost, depending on the material used and the complexity of the job.
At Action Roofing, we offer competitive pricing and flexible financing options so that homeowners can buy quality roofing solutions without hurting their wallets.
Best Roofing Options for Australian Homes
Proper selection of roofing materials is very important for durability, aesthetic, and financial reasons over the long term. Given Australia’s diverse weather conditions, including intense heat, heavy rains, and storms, choosing a roof that can withstand these elements while complementing the home’s design is crucial. Here are some of the most effective types of roofing.
Colorbond Metal Roofing
Colorbond has been a widely popular choice for many people due to its durability, weather resistance and modern appearance. Light in weight, it reduces structural load on buildings and only in one of its many colours and finishes. Its reflective coating keeps the heat off and is also an energy-efficient colour option. It is also very low maintenance, needing no upkeep over time. It is more expensive than concrete tiles, but creates greater insulating effects without noise during heavy rain; however, it is more expensive initially.
Concrete Tile Roofing
Concrete tiles are a less expensive and widely available roofing choice that offers excellent insulation keeping indoors tempered. There are many styles and colours available, allowing the homeowner to achieve the aesthetic they desire. If taken care of, these tiles may last for up to 50 years, thus being a long-term investment. This material is considerably heavier than that of metal roofing. Therefore, the framing must be very strong to bear the weight. They also get wet and become places for moss and algae to grow in humid areas, and can crack with temperature changes down the line.Â
Terracotta Tile Roofing
Terracotta tiles exude timeless beauty and retain their natural colour without fading over time. They provide better insulation, keeping homes cooler in the summer and warmer in the winter. They also are fire-retardant and able to withstand severe weather. They also have a life expectancy of over 50 years, so they make great long-term investments. However, terracotta tiles are heavy and relatively less durable than concrete tiles, making them vulnerable to breakage from heavy impacts e.g., branches falling or unintentional foot traffic during maintenance.
Slate Roofing
Slate roofs are a great choice if you want a luxury look and tight, sturdy durability. It is one of the longest-lasting roofing materials on the market, lasting for over 100 years. Slate is naturally fireproof, eco-friendly, and highly resistant to weathering damage. However, slate roofing is very expensive, both in materials and installation. Its substantial weight can require additional structural support under the roof, which increases construction costs. However, while a great investment piece in terms of durability, the price point is not attainable for all homeowners.
Asphalt Shingles
It is made of asphalt which is a great flexible roofing solution. Their variety of colours and textures makes them a versatile choice for different kinds of homes. Installation is easier and less work-intensive than tiles or metal roofs.
Asphalt shingles, on the other hand, have a shorter lifespan of 15-30 years and are less durable through extreme weather conditions. They can need replacing regularly in windy, hail-prone areas or places with extreme heat.

Roof Replacement Process: What to Expect
Roof replacement is a major investment that improves the safety, durability, and aesthetics of a home.  Knowledge about the process enables a seamless and stress-free experience.
Roof Inspection and Assessment
A professional roofing contractor must conduct a thorough inspection to assess the condition of the current roof, and whether it should be replaced or not. At Action Roofing, we use advanced techniques such as drone imaging and thermal scanning tools to identify hidden structural issues ensuring an accurate evaluation is made before any work is performed.
Choosing the Right Material
The right roofing material is critical to longevity, energy efficiency, and aesthetics. Deciding between a new structure or an addition depends on factors such as budget, climate and design preferences. Metal (Colorbond) roofs, concrete slab tiles, terracotta tiles and slate all offer durability and aesthetics. We at Action Roofing assist homeowners every step of the way and recommend the right material that meets their needs while ensuring functionality and aesthetics.
Removal of the Old Roof
The old roofing system is carefully stripped off to avoid damaging the underlying structure in preparation for the new roof installation. At this point, a thorough examination is done to look for underlying problems, such as weakened supports or water damage. Repairs and reinforcements, if needed, are made to establish a solid base for the new roofing system.
Installation of the New Roofing System
When the old roof has been stripped away and the structure is safe and solid, the new roof system is laid in. The process involves applying protective underlayment, securing battens, and finally laying the chosen roofing material. Properly installed material is important for weather resistivity, insulating properties and longevity. Our experts retain the current industry standards to provide you with the remaining and utmost results.
Final Inspection and Cleanup
Once everything is finished, a final inspection is done to make sure that the work has been completed satisfactorily. These steps ensure that the roof is sound, waterproof, and durable over time for harsh weather conditions. Once approved, a site cleanup is undertaken, clearing away debris, and leaving the property neat and ready to enjoy.
How to Save on Roof Replacement Costs
The cost of a roof replacement can be high, but homeowners can save money without sacrificing a quality job. Using long-lasting materials will save you money over time and minimise the need for maintenance and replacement. That’s where getting multiple quotes from different contractors can help you out, as this gives a range of pricing ideas while ensuring that you are getting quality service. Additionally, can benefit from having the replacement scheduled during off-peak seasons, when roofing services are less requested, thereby reducing costs.
If the roof has sustained storm damage or other insurable events, verifying insurance coverage is key because many policies will provide repair or replacement coverage. Where the roof remains in sound structural condition, restoration options like cleaning, repointing and resealing make economic sense when compared with total replacement. Investigating these options helps homeowners make wise, cost-effective choices and achieve a solid and long-lasting roof.
Final Thoughts
Replacing a roof could be a major investment, but with the right material and appropriate installation, your home could be durable, efficient with energy, and increase in resale value.
