Re-Roofing Procedures and Costs

Understanding Re-Roofing Procedures and Costs

Strengthening Your Own Home

Re-roofing Procedures

Re-roofing is a complex process that defines how your home’s aesthetics and durability will be in the long run. Since the roof makes up about 30 per cent of any home’s façade, it is essential to choose the right materials that will match the overall theme and design, as well as the owner’s personal taste. Equally, roofing systems should be prioritised when strengthening a home’s general build, as it is one of the primary components that directly come in contact with South East Queensland’s extreme weather conditions and everyday elements. To provide an overall idea on re-roofing procedures and costs, here is essential information that should be considered before finalizing a re-roofing strategy for your home.

Re Roofing Procedures

There are basically two ways to reroof your home—to do it yourself or get a professional re-roofing company to cover all the hassles for you. The first option may spell “initially” lower costs, but overall, more time-consuming, labour intensive, and expensive procedures. Hiring professional roofers will not only ensure expertise in the whole process, but will also provide you with more options in terms of costs, materials, strategies, and additional installations that will pass Australian standards. When our jobload is too big we often hire crews from our roofing partners from Pro Roofing Brisbane, if you are looking for a company that has great service and pay careful attention to detail just tell them we sent you.

There are basically nine steps in the process of re-roofing that most companies put into practice and are as follows.

1. Inspection

Specialists from your chosen re-roofing company will visit the site and inspect your roof to see what it needs in terms of size, quality, extensiveness of reroofing, and complexity of the process (E.g. Is your roof pitched or not? Is it easy to access?).

2. Quotation of prices

Based on the actual inspection of the roof, you will be given a comprehensive quote of the total expenses that will be spent. Different materials at varying prices will be offered, as well as additional installations, such as accessories (i.e. sarking, which can only be done when a new roofing system is installed) that you can decide upon. The timeframe for completion of the job will also be estimated by the re-roofing company.

3. Selection of materials

You will, then, choose the type of materials that will be used in re-roofing your home (metal, clay tile, slate tile, terracotta, or colorbond—depending on which ones the company offers). Each type of roofing is made with different materials, has diverse designs and builds, and is made to address varied needs.

4. Delivery of chosen materials

The materials will be delivered to your address for installation. Before the roofers begin the actual process of re-roofing, safety rails and other temporary structures will be installed based on the conditions of the site.

5. Removal of old roofing

Your old roof will be removed. Battens may also be removed, depending on their overall state.

6. Installation of new insulation, sarking and ventilation (if applicable)

Sarking, if included in the package, will be installed prior to the bedding of your chosen roofing material.

7. Bedding of new roofing, installation of flashing

Roof tiles or metal roofing will be bedded, pointed, and fixed.

8. Clean-up of rubbish, debris, and scraps

Re-roofing companies make sure that jobs completed include cleaning the site and the surroundings thoroughly so that debris and scraps do not obstruct the gutter or any part of the roofing system.

9. Final inspection

The roofers will conduct a final inspection to check for cracked tiles, correct installation of sarking, and if materials are properly bedded. It is their responsibility to make sure that their job is completed according to Australian roofing standards. Established companies offer lifetime warranties for re-roofed homes at costs for free or for a cost.

How much does re-roofing cost?

Re-Roofing Costs

Re-roofing costs vary upon the materials used, company hired, the additional installations included, and the size of the roof that needs to be replaced. Technically, the roof size (perimeter) is measured and multiplied by 1.1 (if pitched). The product is then multiplied to the cost per square metre ($80 to $130, give or take) to get the general cost that includes all steps of the process, from inspection to cleaning and final inspection.

Which one is cheaper and which one is more expensive?

While the complexity of the job, classified by the site conditions and roof pitch, among others, is a major factor that contributed to how much your roofer will charge, the materials being used in re-roofing will comprise the bulk of the total price that you will shed out. In general, a metal roof replacement costs around $50 to $100 per square metre, followed by clay tile ($100-$400), slate ($400-$600), and terracotta roofing. Colorbond roofs are among the most expensive nowadays.

Sample Quotations

A few sample quotations, based on past re-roofing services that we completed with the help from Pro Roofing Brisbane, are as follows:

  • 170 square metre, tiled roofing with large flashing in Doncaster = $11,000-$14,000
  • 230 square metre, gutter and downpipe replacement included, fascia cover, metal roofing changed into colorbond, gutter guard installed, and solar hot water unit removed and reinstalled = $18,000-$22,000
  • 145 square metre, tiled roof replaced by colorbond, gutters replaced, timber battens replaced with steel battens = $12,000-$14,000
  • 450 square metre, tile roofing replaced with colorbond, downpipes and gutter replaced = $32,000-$36,000


Australian Roofing Standards: The Basics

Australian Roofing Standards

Whether DIY-ing your roof or having it done by a professional re-roofing company, it is fundamental to have a general knowledge on Australian roofing standards that are strictly enforced in any part of the country. The three major factors that should be considered are: fire and safety, minimum energy efficiency, and acoustic ratings. For details on Building standards in Australia you can visit the Master Builders website.

Energy Efficiency

Installing a new roofing system requires employing the minimum energy efficiency rate set by the Australian government. This means energy usage is minimized through enhanced heating, cooling, and lighting through a well-structured roof and overall building quality. It is, among all the required considerations in Australian roofing standards, one of the most valuable principles that should be considered.


When re-roofing your home, you can always choose to save on costs without sacrificing quality and efficiency in the process and the completion of the job. There are plenty of re-roofing companies that offer the most suitable procedure and quote that will match your personal preferences. In the long run, a durable and expertly installed roofing system will increase your home’s value, protect your family from extreme weather conditions, help you save in energy expenses, and improve your home’s aesthetics.
