Cut Edge Corrosion Treatment Industrial Roofing Experts
VBS Ltd provides certified cut edge corrosion repair & cut edge protection for industrial and commercial metal roofing. Free survey & guarantees.
What Is Cut Edge Corrosion?
Cut edge corrosion is a form of deterioration affecting factory‑coated profiled metal roofing and cladding sheets. It occurs where the protective coating has been cut, trimmed, or where overlaps exist, leaving the raw metal edges exposed. Over time, coating delamination, weather exposure, rainwater, and capillary action cause the exposed edges to rust, peel back, and ultimately perforate if left untreated.

Why Cut Edge Corrosion Happens
-
During manufacture, metal sheets are coated first, then cut to length. These cut edges lack the factory coating protection.
-
The coating at the sheet ends and overlap joints peels back with time due to UV, rain, temperature changes, or environmental pollutants. This exposes the metal to moisture on both the top and reverse sides.
-
Capillary action and water trapped in lap joints accelerate corrosion underneath the sheet overlaps.
-
Coastal, industrial, and high pollution environments exacerbate the problem due to salty air, chemical contaminants, or frequent moisture.
Why It’s a Serious Issue
-
The structural integrity of metal sheets and laps can be compromised, leading to leaks and water ingress.
-
Over time, corrosion spreads beyond cut edges → perforation, which often forces full sheet replacement. This is more expensive and disruptive.
-
Untreated corrosion increases maintenance costs, reduces lifespan, and can damage internal structure, insulation or interior finishings.
-
Aesthetic damage, possible health & safety risks, possible insurance / warranty issues.

Our Proven Process for Cut Edge Corrosion
Inspection & Assessment
We conduct a site survey to identify and map all cut edges, overlaps, areas showing coating peel, rust, or structural weakening.
Preparation
Clean the affected areas thoroughly — remove loose coating, oxidation, rust scale.
Base Coat and Sealant
Apply a corrosion‑inhibiting base coat specially designed for cut edge treatment systems. Ensures adhesion and stops further rusting. Apply the sealant to encapsulate the edge, overlap joints and exposed metal. Colour matching available.

Once cured, final inspection is carried out to ensure watertight finish, durability, and aesthetic condition. We issue guarantee documentation for the system used. Maintenance advice provided.

“Recently used VBS to overclad an asbestos roof that had reached the end of its useful life. The roofing team that we had took great pride in "their roof" and the finished result has transformed the look of the facility.
We decided upon the overcladding approach to reduce the impact upon our production as they could overclad whilst we continued underneath once the sacrificial safety netting was installed.”

“We own a large textile mill and having repaired the life out of the main roof decided it was time to invest and renew the roof. After 8 months of searching for a reputable roofing firm, I came across VBS and the Valentine family. Their professionalism and knowledge was so apparent and the time they were willing to spend with us in helping us decide which method to adopt was refreshing. At no point in this lengthy process did i ever feel under pressure to accept their quotes. We felt very much at ease and made a gut decision to work alongside VBS to renew our 40,000 sqft roof. Time frames were not an issue and works commenced late in 2024 and have been completed and signed off very recently. I highly recommend this lovely family firm especially on large roofing projects such as ours. thank you for a job well done! I am willing to provide photos and share our journey and experiences with VBS to interested parties.”

“Absolutely made up with this company from start to finish. They have completed all works within the promised time frame and to a very high standard. The lads who completed the works were respectful regarding our site procedures, on time every day, and courteous at all times, what a fantastic bunch. We were informed at every stage of the works as to what was required for each stage, the whole job couldn't have run any smoother. I'm not usually as kind when it comes to reviews, but this company deserve all the praise I can give them. We did our homework before choosing VBS Limited, I'm thankful we did, we chose the right company for our needs.”

“I am extremely impressed with the professionalism and attention to detail of the full team including the quote, account and site team.
They overcladd my commercial unit, and the result of my roof over clad was exactly what I was hoping for.
The team were friendly and knowledgeable and answered all my questions.
Overall, I would highly recommend this company to anyone looking for roof over cladding services.
They truly went above and beyond to ensure that I was completely satisfied, and it was clear that customer satisfaction is a top priority for them.
Thank you for a wonderful experience!”

Nathan Markey - Facilities Manager

Really pleased with the roof replacement of our old corrugated cement sheeted apex roof on our warehouse and factory in Bolton with the latest roofing panels. Thanks to the planned work being carried out efficiently and safely it was completed slightly ahead of time and disruption to our factory operation was minimised. The team kept us informed and we could plan around the situation. The new roof panels save a lot of maintenance issues and the bonus has been a huge improvement from increased natural light. It has visually transformed the whole factory, and is helping us provide and elevated impression to our customers. The outcome has been better than expected. Very impressed with VBS

FAQs
Q: When should I act?
A: As soon as signs of coating peel, rust at edges or lap joints appear. Early treatment is far cheaper and less disruptive.
Q: Can existing treatments be over‑coated or do they need full removal?
A: It depends on the system and condition. Many suppliers require removal of old failed layers before applying certain high performance systems. Overcoating may hide deeper corrosion.
Q: How long does treatment take?
A: Usually depends on extent and access, but isolated repairs can often be done quickly, while large scale operations may need planned scheduling.
Q: Will the colour match my existing sheets?
A: Many topcoats come in colour ranges allowing blending. For best aesthetic result, masking and proper finishing are used.
