Cut edge corrosion repair is the process of treating and restoring the exposed edges of metal roof sheets that have become susceptible to rust and corrosion. This repair involves cleaning the affected areas, applying a rust inhibitor, and sealing the edges with a specialised protective coating to prevent further deterioration. The goal is to restore the integrity of the metal roofing and extend its lifespan by stopping the progression of corrosion at the vulnerable cut edges.
What Is Cut Edge Corrosion Repair?
Cut edge corrosion repair is the process of addressing and restoring the exposed edges of metal roof sheets, which are particularly vulnerable to rust and corrosion after the original protective coating is removed during installation. This type of repair typically involves several key steps: cleaning the affected area to remove any rust or debris, applying a rust inhibitor to halt the corrosion process, and then sealing the edges with a specialised protective coating designed to prevent further deterioration. The protective coating, often a high-performance paint, creates a barrier that shields the metal from moisture, oxygen, and other corrosive elements.
Effective cut edge corrosion repair not only stops the progression of existing corrosion but also prevents future damage, significantly extending the lifespan of the roofing system. This process is essential for maintaining the structural integrity of metal roofs, particularly in environments with harsh weather conditions or high exposure to pollutants. Regular maintenance and timely repairs can prevent small issues from developing into major problems, helping to avoid costly replacements. Therefore, investing in proper cut edge corrosion repair is a cost-effective strategy for preserving the durability and performance of metal roofing systems.

How Do You Repair Cut Edge Corrosion?
To repair cut edge corrosion, clean the affected area, apply a rust inhibitor, and seal the edges with a protective coating. Cut edge corrosion occurs when the protective layer on roof sheet edges is compromised, exposing the metal to moisture and air. The first step, surface preparation, involves thoroughly cleaning the area to remove rust and contaminants. Next, treating the corrosion with a rust inhibitor halts the rusting process. Finally, applying a specialised protective coating restores the protective layer, preventing further damage and helping to reduce future maintenance and repair costs.
- Clean the Affected Area
- Apply a Rust Inhibitor
- Seal the Edges with Protective Coating
1. Clean the Affected Area
Begin by meticulously cleaning the affected section of the roof sheet to remove rust, grime, and other contaminants. Proper surface preparation is vital to ensure the rust inhibitor and protective coating bond effectively with the metal, offering lasting protection. Use appropriate cleaning tools and techniques to make sure the area is free from debris and ready for the next treatment step.
2. Apply a Rust Inhibitor
Once the area is clean, apply a rust inhibitor to the exposed edges where cut edge corrosion has developed. The rust inhibitor halts the corrosion process by chemically neutralising the rust, preventing it from spreading further. This step is essential to ensure the corrosion is fully treated before applying the final protective coating.
3. Seal the Edges with Protective Coating
Finally, seal the treated edges with a specialised protective coating designed for metal surfaces. This coating reinstates the protective layer that was compromised when the roof sheets were cut, shielding them from future exposure to moisture and air. By applying this coating, you not only prevent further damage but also reduce maintenance and repair costs, ultimately extending the lifespan of your roofing system. Taking these steps ensures your roof remains durable and well-protected, safeguarding your investment for years to come.
What Are The Signs Cut Edge Corrosion Repair Is Required?
The signs cut edge corrosion repair is required include; visible rust or discolouration along the edges of roof sheets, indicating the protective coating has been compromised. You may also notice peeling or flaking of the existing coating, which exposes the underlying metal to the elements. Water ingress or leaks near the sheet edges can be another indicator, as corrosion weakens the metal, leading to gaps and vulnerabilities. Additionally, if the roof sheets or metal cladding exhibit signs of distortion, such as warping or buckling, it could be a result of prolonged corrosion and a clear signal that repair is necessary. Regular inspections can help identify these early signs, allowing for timely repairs that prevent further damage.
- Visible Rust or Discolouration Along Edges
- Peeling or Flaking of the Protective Coating
- Water Ingress or Leaks Near Sheet Edges
- Distortion, Warping, or Buckling of Roof Sheets
1. Visible Rust or Discolouration Along Edges
Visible rust or discolouration along the edges of roof sheets is the most apparent sign cut edge corrosion repair is needed. When the protective coating deteriorates, the exposed metal reacts with moisture and oxygen, leading to oxidation, which manifests as rust or discolouration. This not only affects the aesthetic appearance of the roof but also signals underlying structural damage that could worsen if ignored. Regular inspections help detect these early signs, allowing for timely repairs to prevent further deterioration and expensive repairs.
2. Peeling or Flaking of the Protective Coating
Peeling or flaking of the protective coating is another clear indicator cut edge corrosion repair is required. As the coating starts to degrade, it loses its ability to shield the underlying metal from environmental factors like moisture and UV exposure. Once the coating begins to peel or flake, the metal becomes exposed and vulnerable to rust and corrosion. Addressing this issue promptly by applying a new protective layer can prevent further damage and extend the lifespan of the roof sheets.
3. Water Ingress or Leaks Near Sheet Edges
Water ingress or leaks near the edges of roof sheets are significant signs cut edge corrosion has compromised the roof's integrity. Corrosion weakens the metal, creating gaps and vulnerabilities where water can penetrate. This can lead to internal damage to the building, including to insulation, electrical systems, and structural components. If you notice any signs of water leakage, it is crucial to inspect the roof edges for corrosion and take immediate action to repair the affected areas to prevent further damage.
4. Distortion, Warping, or Buckling of Roof Sheets
Distortion, warping, or buckling of roof sheets often occurs as a result of prolonged corrosion, which weakens the metal’s structural integrity. When the metal edges corrode, they lose strength, leading to deformities in the roof sheets. These issues not only affect the roof’s appearance but also pose a risk to the overall stability of the structure. Repairing cut edge corrosion at the first sign of such distortion is essential to prevent more extensive damage and ensure the roof remains secure and functional.
What Is The Best Cut Edge Corrosion Repair Solution?
The best cut edge corrosion repair solution is Desmoflex Fiberfix, particularly in situations where the roof requires added reinforcement due to high exposure or wear. Desmoflex Fiberfix is favoured for its ease of application, elasticity, and the inclusion of glass fibre particles, which enhance the durability and strength of the protective coating. For industrial roofs with complex profiles or contoured surfaces, Desmoflex Thix is superior due to its thixotropic properties and anti-slump capabilities, ensuring excellent adherence and coverage on challenging surfaces. Another strong option is MPM Starflex Monotix, which offers robust protection with similar thixotropic properties, making it ideal for industrial applications where maintaining the roof’s integrity is essential.
