Rooflock Twelve HR for Metal Cladding & Roofs
Rooflock Twelve HR for metal cladding and roofs is a guaranteed coating system for refurbishing metal pitched roofs and wall cladding, that is appreciated by specifiers for its very hardwearing finish (does not get pecked by birds) and by contractors for its ease of use. Suited to general refurbishments and dilapidations projects.
For application either by spraying or by brush and roller.
Very high scratch resistance.
A guaranteed coating system
With warranties of up to 25 years available in certain applications, you have the assurance of a high performance and durable coating system. (For projects requiring a warranty, Rooflock technical team must be consulted prior to commencement of project.)
WATERPROOFING WARRANTY available
Make your metal roof waterproof again - go further than a protective-only coating.
Available on a project-by-project basis, and subject to a site survey, a roof waterproofing warranty is available to address the common water ingress issues found on metal roofs.
(For projects requiring a waterproofing warranty, Rooflock must be consulted prior to commencement of the project).
Superior aesthetics - does not attract dirt
The durable, semi-gloss UV stable finish provides superior aesthetics and a neat smooth appearance that does not attract dirt or lichen like other coatings.
Very hardwearing finish that does not get pecked by birds.
Very easy to use - spray directly from the tin
The low viscosity easy-to-use formulation gives significant time savings compared to other coating types. It is applied using either brush and roller or airless spraying techniques. When using spray application, installation is rapid and weather-related delays are reduced.
No catalyst required - saves time and labour with quick cure speeds
The cure time of Rooflock Twelve HR is approx 2 hours at 20°C. There is no requirement for a separate catalyst, saving time and labour costs.
Treats corrosion
Includes rust-inhibiting base coat primer to treat cut edge corrosion and other damaged areas.

What is cut edge corrosion?
Cut Edge Corrosion is the term given to corrosion that develops at the factory guillotined tail ends of profiled steel roof sheets. As the bare steel at the sheet end begins to corrode, the original coating peels off and the corrosion moves progressively up the roof sheet.
Additionally, as the original mid-lap sealants break down, water can be driven in by capillary action and retained between the roof sheets, exacerbating the corrosion from within.
It is estimated that that around 2 in 3 of metal roofs in the UK are affected by cut edge corrosion, and if left unchecked, this issue can progress to become a serious problem affecting both the weatherproofing and structural
integrity of the roof. The roof can deteriorate to the extent that replacement is the only option.
However, by addressing cut edge corrosion early with application of a dedicated metal protection product such as Rooflock Twelve HR Coating System, potentially costly and disruptive remedial action can be avoided.
Rooflock Twelve HR Coating – reducing embodied carbon write-off
CAt 9.85t CO2e, steel has one of the highest values of embodied carbon in construction (even higher than concrete). When a steel roof is removed and replaced, this embodied carbon is written off and added directly to the organisation’s Scope 3 emissions reports.
By making a timely, sustainable choice and using Rooflock Twelve HR Coating to either treat cut edge corrosion or as coating to the entire metal roof, the environmentally costly option of roof replacement can be avoided, and the roof is protected
for the future.
