Metal Roof Restoration
Profiled metal roof edges
Cut Edge Corrosion
Treat damaging cut edge corrosion on suitable metal roofs. Our specialist systems are designed to restore weathertightness, with 20-year guarantees available on qualifying systems subject to written terms.
Survey note
What is cut edge corrosion treatment?
Cut edge corrosion treatment protects exposed, corroding edges of profiled metal roof sheets that remain suitable for refurbishment. Survey findings and the chosen system determine preparation, primer, edge sealing and protective coating requirements. Perforated or otherwise unsuitable sheets may need replacement rather than coating.
Why Specialist Treatment, Not Standard Painting
A suitable treatment approach depends on the corrosion extent, substrate condition and specified product. The survey identifies the preparation, primer, edge treatment and topcoat required for the project.
Product selection depends on substrate, movement, exposure and preparation requirements. Applicable product data and test information are reviewed within the written specification.
How Is Cut Edge Corrosion Treatment Specified?
The treatment sequence is determined by the survey and written specification. It may include condition records, preparation, primer, edge treatment and protective topcoats; the programme identifies any operational restrictions or access arrangements.
The programme and access method depend on roof size, condition and site constraints and are set out in the fixed-price written quotation.
Treatment vs Full Re-Sheeting
Full metal re-sheeting requires removal of the existing roof, protection of the building interior and disposal of the old sheets. Cut edge treatment can retain structurally sound sheets and reduce disruption where the roof condition is suitable.
Treatment may be suitable when sheet profiles remain structurally sound and survey findings support the selected system. Where sheets are perforated or distorted, the written recommendation may instead identify partial replacement or over-roofing.
What Does Cut Edge Corrosion Treatment Cost?
The price depends on corrosion severity, access requirements, preparation and the system specified. Qualifying systems can include a 20-year guarantee subject to written terms.
Pricing is fixed in writing following our free condition survey. The quotation reflects the access method and project-specific scope.
What the specification covers
01
Manage Corrosion
Specified treatments are designed to manage corrosion on suitable metal roof sheets following condition assessment.
02
Treat Exposed Edges
Specified coatings can be used to protect prepared cut edges where corrosion has been identified.
03
Specified Weatherproofing Details
Prepared eaves, ridges and flashings can be detailed within the specified treatment where condition assessment supports it.
04
Assess Replacement Options
Where survey findings support treatment, suitable roof sheets may be retained instead of complete re-sheeting.
05
Rope Access Capability
Rope access may be used where the project-specific access plan and risk assessment confirm it is suitable.
06
Colour-Matched Finishes
Colour matching may be available, subject to the specified product and existing roof finish.

Protective Coating
Coat type, number and application requirements follow the selected product data and written specification.
Common Questions
What causes cut edge corrosion on metal roofs?
When profiled metal roof sheets are cut to length during installation, the factory-applied protective coating is removed at the cut edge, leaving raw metal exposed. Over time, moisture, air, and atmospheric pollutants oxidise the exposed metal, creating rust that gradually spreads up the face of the sheet. The galvanised protective layer degrades first, followed by rust propagation into the base steel.
How much does cut edge corrosion treatment cost?
Pricing depends on the extent of corrosion, roof access requirements and the system specified. We provide free condition surveys and fixed-price written quotations with no obligation.
How do I know if my commercial roof has cut edge corrosion?
The most visible signs are orange or brown rust staining running down the face of roof sheets from the lower cut edge, dark streaking on external walls below the roofline, and visible pitting or flaking at the sheet edges. In more advanced cases, you may notice water ingress during heavy rain. We offer free condition surveys with a written report and photographic documentation.
Is cut edge corrosion treatment better than replacing the roof?
Treatment can avoid full re-sheeting when the sheet profiles are still structurally sound and corrosion is in the early to mid stages. Our free survey assesses the extent of corrosion and informs the recommendation on whether treatment or replacement is appropriate.
How long does cut edge corrosion treatment last?
Qualifying treatment systems can carry a 20-year guarantee, subject to the written terms supplied for the project. The specified treatment includes preparation, primer, edge sealing and a protective topcoat.
Can you treat cut edge corrosion without scaffolding?
Rope access may avoid scaffolding where the roof, access plan and risk assessment make it suitable. The access method is confirmed for each project following survey.
How long does cut edge corrosion treatment take?
Project duration depends on the specified product, weather, access, roof condition and scope. The written programme and product system data control sequencing, cure periods and completion requirements for the project.
