Ray, Matt & crew worked tirelessly to get the job done. They did an Excellent job!Posted on Google Andrew WightTrustindex verifies that the original source of the review is Google. Ray and the team were delightful to deal with right from the first moment. Ray's passion for roofing and building (and life!) are incredible and he runs a tight ship. They also went above and beyond to touch up paint and fix a cracked tile. After initially struggling to even find a roofer who would return our calls at all, we're grateful that we ended up discovering Fortified. You'll have to look long and hard to find someone better.Posted on Google sumegh patneTrustindex verifies that the original source of the review is Google. Amazing work. Quick, efficient, considerate, inclusive, on schedule. Can’t find any fault. Especially, Matthew. Well done job!Posted on Google Ana VanderleerTrustindex verifies that the original source of the review is Google. Fortified roofing were great throughout the whole process. Very prompt with the quote and replies. Very easy to pay and make business with. They did an excellent job on our roof removing the old asbestos roof and putting in a new roof colour bond on the same day. We checked when they were finished and it looks amazing, ever since we haven't had to use our heaters because the insulation in the new roof is excellent.Posted on Google Andrew McDougallTrustindex verifies that the original source of the review is Google. Great ServicePosted on Google Lisa MBTrustindex verifies that the original source of the review is Google. We had a fantastic experience with Fortified Roofing. With all the rain Brisbane has experienced this past year, and Cyclone Alfred looming, we were very nervous about the state of our old tile roof. Matt and his team (and especially Ray) were professional, friendly and worked tirelessly - right up to the last possible moment before the weather turned too bad – to make sure everything was secure and ready. During and after the cyclone, our new roof held up beautifully. If you’re looking for a roofing company you can trust, especially in high-stress situations, Fortified Roofing can’t be beat.Posted on Google Claire DaltonTrustindex verifies that the original source of the review is Google. I reached out to Matt who installed our roof prior to purchasing our property. Unfortunately, our builder installed a patio roof which didn't meet code and caused leaking. Matt fixed the issue withoiut delay and his communication was excellent. I can't fault this company and would use them again.Posted on Google Nirmal SinghTrustindex verifies that the original source of the review is Google. Hi had Matt and his team replace an old roof on my old Queenslander using colorbond They did a fantastic job completed the job promptly Left the place clean and tidy Looks fantastic Thanks Matt couldn’t be happier !Posted on Google Marko MaljkovicTrustindex verifies that the original source of the review is Google. Very professional from quote to completion. Highly recommended.Posted on Google Suresh IyengarTrustindex verifies that the original source of the review is Google. I took quotes from five different roofing installers. I consider myself lucky to come across Oz Roofing (Fortified roofing group). Matt Turnbull and his father seventy year old Ray Turnbull are both down to earth people. They were honest, fair and guided me to make the right choice of roofing to replace my asbestos roof. Ray was present throughout the process of re-roofing and took special interest to make sure the job is done perfectly. I will have no hesitation to recommend Fortified roofing for their honest, friendly and fair dealings.

Commercial Roof Replacement FAQs
How long does a commercial roof replacement take?
The time required for a commercial roof replacement depends on several factors, including the size of the building, the type of roofing material used, and weather conditions. On average, a commercial roof replacement can take anywhere from a few days to several weeks. Smaller buildings with straightforward roofing structures may only take a few days, while larger or more complex projects, such as shopping centers or industrial warehouses, can take longer. Our team at Fortified Roofing Group conducts a thorough inspection and creates a tailored timeline for each project to ensure minimal disruption to your business. We also work closely with your schedule to accommodate any operational requirements. By planning each stage carefully and ensuring all safety and quality protocols are followed, we aim to complete every project as efficiently as possible, without compromising on the quality of the work.
What is the best roofing material for commercial buildings in Brisbane?
Choosing the best roofing material for your commercial building depends on several factors, including the local climate, the structure of the building, and your budget. In Brisbane, where weather conditions range from heavy rains to intense heat, materials like Colorbond and Zincalume are highly recommended. These roofing materials offer excellent durability, thermal efficiency, and corrosion resistance, which are crucial in Brisbane’s fluctuating climate. Colorbond roofing is particularly popular because it combines strength with a modern aesthetic, while Zincalume provides cost-effective, long-lasting protection. Both materials are engineered to handle harsh conditions, making them ideal for commercial properties that require low maintenance. Our team at Fortified Roofing Group will assess your building’s needs and recommend the best roofing material for your specific situation to ensure maximum protection and long-term savings.
How do I know if my commercial buildings' roof needs replacing or just repairs?
Knowing whether commercial buildings roof needs a full replacement or just repairs can be difficult without a professional inspection. Key signs that your roof may need replacing include frequent leaks, sagging areas, significant rust or corrosion, and visible damage to roofing materials. If you’re noticing leaks after every storm or having to arrange multiple repairs within a short timeframe, it may be more cost-effective to invest in a replacement. Additionally, older roofs, especially those made from materials like decramastic tiles, may no longer be providing adequate protection. Our experienced team at Fortified Roofing Group can conduct a thorough inspection of your roof, identify the key issues, and provide an honest recommendation. We’ll explain the long-term benefits and costs associated with both repair and replacement, helping you make the most informed decision for your business.
How much does a commercial roof replacement cost?
The cost of a commercial roof replacement varies depending on factors such as the size of the building, the type of roofing material chosen, the complexity of the project, and any specific requirements like guttering or insulation. On average, a commercial roof replacement can range from a few thousand dollars for smaller properties to much more for larger buildings with complex roofing systems. At Fortified Roofing Group, we provide detailed and transparent quotes, so you know exactly what to expect before any work begins. We offer a range of roofing materials, from Colorbond to Zincalume, each with varying price points to suit different budgets. Our goal is to provide a durable, long-lasting solution that fits your financial needs while delivering exceptional quality and protection for your property.
How long will a new commercial roof last?
The lifespan of a new commercial roof depends largely on the materials used and the quality of the installation. On average, a well-installed commercial roof using high-quality materials like Colorbond or Zincalume can last anywhere from 20 to 30 years or more with proper maintenance. Factors such as the local climate, the type of business, and regular upkeep can also impact the roof’s longevity. For example, businesses in coastal areas may require additional protection due to higher levels of salt and moisture in the air. At Fortified Roofing Group, we use top-quality materials and adhere to strict installation standards to ensure your roof lasts as long as possible. We also offer maintenance plans to help extend the life of your roof and protect your investment.
What is involved in the commercial roof replacement process?
The commercial roof replacement process involves several key steps to ensure a seamless and efficient project. First, we conduct a detailed inspection of your existing roof to assess its condition and identify any issues. Next, we develop a comprehensive plan that outlines the materials to be used, the timeline, and any safety protocols. During the replacement, our team will remove the old roofing materials and prepare the surface for the new roof. We then install the new materials, ensuring proper sealing and weatherproofing at every stage. For projects that include guttering, we’ll also install or replace gutters and downpipes to ensure optimal water flow. Throughout the process, we prioritize safety and quality, ensuring minimal disruption to your business operations. Once the installation is complete, we conduct a thorough inspection to confirm everything meets our high standards.
Will my business need to shut down during the roof replacement?
In most cases, your business will not need to completely shut down during a roof replacement, but there may be some temporary disruptions. The level of disruption depends on the size of the roof, the complexity of the replacement, and the type of business you operate. At Fortified Roofing Group, we strive to minimize any impact on your daily operations by working around your schedule and coordinating with other trades where necessary. We also use safety protocols to ensure the protection of your employees, customers, and property. In cases where shutting down certain areas is unavoidable, we will communicate with you well in advance to ensure the process is as smooth as possible. Our goal is to complete the replacement efficiently while keeping your business running with minimal interruption.
What are the benefits of replacing my commercial roof instead of repairing it?
While repairs can be a quick fix, they may not always offer a long-term solution, especially for older or severely damaged roofs. Replacing your commercial roof provides several benefits, including enhanced protection against leaks and weather damage, improved energy efficiency, and a modern, professional appearance. A new roof can also reduce maintenance costs, as it eliminates the need for constant repairs. Additionally, upgrading to materials like Colorbond or Zincalume can improve thermal efficiency, helping to reduce cooling costs, which is particularly beneficial in Brisbane’s hot climate. Investing in a roof replacement is often more cost-effective in the long run, as it minimizes disruption to your business and ensures your property is well-protected for years to come. Our team will assess your roof’s condition and help you determine the best option for your building.
