DIY work can be enjoyable and satisfying, save you money, and avoid the inconvenience of waiting for an appointment or being unable to have work done at a time that suits you. For some projects that you might be tempted to DIY, the risks and requirements can actually mean that calling in the professionals is the most sensible solution.

One home improvement that you might want to complete yourself is metal roofing. You might think that installing metal sheets yourself is simple enough that professional services are a waste of money.

Licenses for DIY metal roofing

First of all, let’s consider the legal requirements for DIY metal roofing in Queensland. For metal roofing installation and repairs taking place throughout the state, it’s necessary to be appropriately licensed by the Queensland Building and Construction Commission. This includes having a license for cutting metal tiles or installing pre-fabricated metal roofing tiles.

Professionals pay fees and demonstrate that they meet the requirements for licensing. They also have to renew licenses as necessary. For consumers, this gives you the added benefit of having confidence that the professionals you hire meet the necessary standards. If you don’t possess the appropriate license it could create more significant problems for you later on. These include the roof performing ineffectively due to a lack of certified expertise. If you work as a roofer and have the appropriate licenses you might be in a position to install your own roof at home, but otherwise, this might be best left to licensed professionals.

The risks of installing your own roofing

Aside from licensing requirements, installing your own metal roof comes with a significant level of risk. It’s worth considering the consequences of the risks associated with this work and deciding if you want to accept the burden. Risks are present whilst you’re working on the roof and afterwards. These are some of the risks that are commonly related to installing a DIY metal roof.

Working at a height

Working at a height without the appropriate safety training and equipment poses a real risk. Without the knowledge of how to work safely on a roof, there’s a risk of falling, which could cause serious injury and even death. Working at a height close to electrical lines can also pose a serious risk of harm. Professional roofers are fully trained to work safely and carefully on roofs and at heights. They’re able to work efficiently without posing harm to themselves or other members of their team. When you’re considering a DIY metal roof, it’s important to recognise the risk of severe injury this might cause.

Risk of leaks

The primary purpose of a roof is to protect the interior of the building from leaks and debris. Installing your own roof without the necessary knowledge and training can mean there are more likely to be faults. The roof also may not last as long as when it’s installed by professionals. An ineffective roof can increase the chances of leaks in the property, which can damage the building’s structure as well as possessions inside the building. Leaks can cause substantial damage that’s costly and time-consuming to repair, so a sub-standard DIY roof simply isn’t worth the trouble.

Insurance issues with DIY roofs

In some cases, a roof that isn’t installed by professionals can cause difficulties with your insurance provider. Before you proceed with any kind of roof installation, it’s vital to check the terms of your insurance policy. This might include stipulations about what type of DIY work is permissible. If you need to claim on your insurance, your claim might be affected by having an unapproved DIY roof. When you choose professional roof installation, you can be certain that the roof complies with insurance requirements and that it won’t present a problem when you need to renew or claim on your policy.

Contact the professionals

Whilst it may be tempting for DIY fans to embark on their own metal roofing project, in most cases the risks are simply too great. As well as the practical risks of accidents and injury whilst you work, installing your own roof can affect your insurance policy and might be less effective than a roof installed by a professional team. Lack of appropriate licensing can also be an obstacle when you’re installing a roof yourself.

Choosing professional services is worth the financial investment for the greater peace of mind that it brings. If you’re looking for metal roofing services in Townsville get a quote from Top To Bottom Plumbing now.

Roofing Issues? Here’s How the Pros Fix Them

By Top To Bottom Plumbing • July 29, 2025

Roofing Issues? Here’s How the Pros Fix Them When it comes to protecting a property, the roof is the first line of defence against the elements. Yet many property owners overlook the importance of timely maintenance and repairs until small issues become major headaches. Whether you’re a homeowner or running a business, addressing roofing problems early can prevent costly damage to interiors, structural elements, and personal belongings. Professional roofing services don’t just patch holes—they deliver thorough assessments, quality materials, and skilled workmanship to keep roofs safe, functional, and looking their best. In this blog post, we’ll explore a few common roofing issues and how roofers tackle them. Leaky Roofs: Why Professional Repairs Are Essential A leaking roof is one of the most common—and damaging—issues a property can face. Even small leaks can cause structural damage, mould, and stained ceilings. Because water often travels before appearing indoors, it’s important to have a professional accurately find and repair the true source. Professional roofers take a thorough approach to ensure leaks are properly resolved: Locate hidden entry points using inspection tools. Replace damaged flashings or tiles that allow water to enter. Apply high-quality sealants and membranes to restore watertight protection. With expert repairs, a leaking roof can be transformed from a persistent problem into a reliable shield against the elements. Storm Damage Assessment: Restoring Safety & Integrity Severe weather can batter roofs with high winds, hail, and torrential rain, often leaving behind obvious and hidden damage that threatens a building’s integrity. Even minor storm impacts can create weaknesses that lead to serious problems if left unaddressed, including leaks, mould, and structural instability. Professionals know what to look for after a storm to catch damage early and prevent further issues: Inspect for lifted or missing tiles and metal sheeting. Check seals and flashings for breaks that let water in. Assess structural damage or weakened roof trusses. Thorough post-storm assessments help document damage for insurance claims, prioritise urgent repairs, and ensure the roof is restored to provide reliable protection for occupants and their belongings. Dealing with Rusted or Corroded Metal Roofing Metal roofing is known for its durability and long lifespan, but it’s not immune to corrosion, especially in areas exposed to salt air or high humidity. Over time, rust can develop and spread if left untreated, weakening roof sheets, compromising fixings, and eventually leading to leaks or structural failure. Professionals provide tailored solutions to address corrosion effectively: Inspect for rust spread and depth of damage. Treat minor rust with anti-corrosion coatings. Replace severely corroded sheets or fasteners. Sagging Roof Structures: Hidden Dangers Uncovered A sagging roof isn’t just unsightly—it’s a warning sign of serious underlying problems. Possible causes include water damage weakening timber supports, structural overload, or long-term neglect. Left unaddressed, sagging can lead to partial collapse. Professionals approach this carefully: Conduct detailed inspections to assess the extent and cause. Replace or reinforce damaged structural components. Ensure repairs meet all building standards for safety. Comprehensive structural repairs restore the roof’s appearance and integrity, helping ensure the building remains safe and secure well into the future. Blocked or Damaged Roof Gutters & Drainage Systems Roof drainage is often overlooked until problems become impossible to ignore. Blocked or damaged gutters and downpipes can cause water to overflow in the wrong places, damaging fascia boards, walls, and even the foundations of a building. Overflowing water can also lead to unsightly stains and encourage mould growth around the home. Professional roofing services ensure: Thorough cleaning of gutters and downpipes to restore flow. Repairs or replacements for cracked, rusted, or sagging sections. Recommendations for guards or regular maintenance schedules. Reliable gutter maintenance and repairs help prevent costly water damage and ensure the entire roof drainage system stays effective in all weather conditions. Poor Roof Ventilation & Its Impact on Your Home Roof ventilation is critical for managing heat and moisture in roof spaces. Without adequate ventilation, a home can experience excessive heat buildup in summer, condensation issues in winter, and accelerated deterioration of roofing materials. Over time, poor ventilation can also contribute to mould growth and higher energy costs as heating and cooling systems work harder. Professionals assess existing ventilation and offer tailored solutions such as: Installing ridge vents, whirlybirds, or eaves vents to encourage natural airflow. Balancing ventilation to prevent moisture build-up that can damage insulation and structural components. Providing advice on best practices for maintaining energy efficiency and indoor comfort. Properly designed and installed ventilation improves comfort year-round and helps extend the lifespan of the roof by reducing heat stress and moisture-related damage. Ageing & Weathered Roofing Materials: When to Replace All roofing materials deteriorate over time due to constant exposure to sun, wind, rain, and temperature changes. Older roofs can develop issues like cracked or broken tiles, faded or corroded metal sheets, or weakened underlays without reliable protection. Professionals help determine when repairs are no longer enough and replacement is the better option: Detailed inspections to evaluate overall condition. Advice on the remaining lifespan and risks of delaying replacement. Planning re-roofing projects that improve protection and add value. Roofers specialise in delivering safe, efficient roof replacements using durable, high-quality materials designed to withstand harsh weather and extend the life of the roof for years. The Value of Professional Roof Inspections & Maintenance Preventive maintenance is far more cost-effective than emergency repairs after a failure. Regular professional inspections catch small problems before they escalate, helping property owners avoid unexpected disruptions and expensive damage. Professional maintenance typically includes: Checking for loose or broken tiles, flashings, and ridge caps that can let water in or be dislodged in high winds. Inspecting sealants and joints for signs of cracking or wear that compromise waterproofing. Clearing gutters and drains to prevent blockages that cause water to overflow and damage walls or foundations. Assessing overall roof condition to identify early signs of ageing, corrosion, or structural movement.
