Curing Cut-Edge Corrosion

With years of experience in the roofing industry, Cure Roofing possesses an unparalleled level of expertise in addressing cut edge corrosion. Our team of skilled professionals, including technicians and project managers, have in-depth knowledge of the latest industry practices and techniques. We continually invest in training to stay updated with advancements in materials, coatings, and corrosion prevention methods, ensuring that our clients receive the highest quality services.

What is Cut-Edge Corrosion?

Cut-edge corrosion is a common issue that often begins as edge peel at the cut edges of metal sheets. This typically happens when sheets are sheared to length, leaving the base metal unprotected. Interestingly, older generations of plastisol coatings used to fail across the entire roof. However, with the development of more durable coatings with extended lifespans (initially 25 years and now 40 years), cut-edge corrosion has emerged as a distinct problem.

In recent years, various commissioned reports have highlighted the escalating levels of environmental pollution. Consequently, contaminated rainwater tends to accumulate in the exposed overlap joint due to capillary action and surface tension. This trapped rainwater eventually seeps into the coating, whether it’s PVC, Plastisol, or Polyester, and leeches into the protective zinc oxide layer, thus exposing the bare metal. As more zinc becomes exposed higher up on the substrate, the factory-applied coating loses adhesion to the steel, resulting in lifting and curling. Ultimately, once both the top and the reverse sides of the metal are exposed, corrosion occurs.

Quality is the cornerstone of our approach. We understand that cut-edge corrosion poses a significant threat to the durability and performance of your roof. Therefore, we use only the finest materials and coatings from trusted suppliers to provide superior corrosion protection. Our skilled craftsmen adhere to strict quality control measures throughout the treatment process, ensuring that every project meets or exceeds industry standards.

Cut-Edge Corrosion Solutions

Cut-edge corrosion occurs when the protective coating on metal roof sheets deteriorates over time, leaving the exposed edges vulnerable to rust and corrosion. At Cure Group, we offer a range of effective solutions to address this issue:

Cut Edge Treatment

Our expert technicians thoroughly clean the affected areas, removing any existing corrosion and loose coatings. They then apply specialist primers and high-performance coatings to protect the exposed edges from further corrosion, ensuring a durable and long-lasting solution.

Coating Maintenance

Regular maintenance is crucial to extend the lifespan of the coating and prevent the recurrence of cut-edge corrosion. We provide comprehensive maintenance programs tailored to your specific requirements, including periodic inspections, cleaning, and reapplication of protective coatings as needed.

Roof Refurbishment

When the extent of cut-edge corrosion is significant, a roof refurbishment may be required. Our team of professionals assesses the roof’s condition and recommends appropriate solutions, which may include replacing damaged sheets, treating cut-edge corrosion, and applying new protective coatings to ensure the roof’s structural integrity and longevity.

Frequently Asked Questions

What is cut-edge corrosion?

Cut-edge corrosion refers to the deterioration of the protective coating along the cut edges of metal roof sheets. Over time, exposure to the elements can cause the coating to degrade, leading to rust and corrosion.

How does cut-edge corrosion occur?

Cut-edge corrosion occurs due to the natural ageing process of metal roof sheets. The original protective coating gradually breaks down, leaving the exposed edges susceptible to moisture penetration and corrosion.

What are the signs of cut-edge corrosion?

Signs of cut-edge corrosion include rust stains, flaking or peeling coating, and visible deterioration along the edges of metal roof sheets. Water ingress, leaks, and compromised structural integrity may also indicate cut-edge corrosion.

Why is it important to address cut-edge corrosion?

It is essential to address cut-edge corrosion promptly to prevent further deterioration and potential damage to the roof structure. Failure to address it can lead to leaks, water damage, and a shorter roof lifespan.

Can cut-edge corrosion be repaired?

Yes, cut-edge corrosion can be repaired. The process involves cleaning the affected area, removing loose or corroded material, and applying specialised coatings to protect the edges and prevent future corrosion.

How long does cut edge corrosion treatment last?

The longevity of cut-edge corrosion treatment depends on various factors, such as the quality of the coatings used, the severity of the corrosion, and the environmental conditions. With proper treatment and regular maintenance, the repaired edges can remain protected for many years.

Does cut-edge corrosion treatment affect the appearance of the roof?

No, cut-edge corrosion treatment is designed to blend seamlessly with the existing roof. High-quality coatings are available in a range of colours to match the roof’s appearance and provide a visually appealing finish.
