Triggered by the cut edge of a metal sheet being insufficiently coated during the manufacturing stage, any untreated metal edge exposed to the elements is vulnerable to Cut Edge Corrosion. The process is accelerated by water being retained within the laps and joints of a roof’s structure, with the potential for oxidisation (rusting) to also occur.
Keep an eye out for blisters, cracks and discolouration on your roof sheet, with extra monitoring around the laps and joints of the structure.
Early identification of the problem is key when it comes to Cut Edge Corrosion, as if left untreated, it can quickly progress further into the metal and cause more than a cosmetic problem for your roof – including leaks and brittle sheets, which can affect the integrity of your building. Lack of identification and treatment can even lead to a complete re-roof in the worst cases. As specialists in the roofing industry, HS RoofClad recommend including an annual Roof Condition Survey within your Planned Preventive Maintenance (PPM).
Early treatment will not only save you money in the long run but will also prolong the life of your cladding and roof sheets, preventing potentially lengthy disruptions to your business, should Cut Edge Corrosion be left to fester for long periods of time.
The first step in treating Cut Edge Corrosion is to inspect the damage and determine the level of repairs required. Following inspections, the entire area will require a thorough clean to remove both rust and dirt, enabling waterproof encapsulation of the affected area to be laid effectively. Further protective layers of waterproofing should then be applied to allow for increased protection – most waterproofing treatments carry a manufacturer supported warranty of 10 to 20 years.
It is important to bear in mind that, if Cut Edge Corrosion is left untreated for long periods of time and the damage is extremely severe, preventative measures may not be suitable and complete removal of the entire metal sheet may be required.
