Rooflock Twelve for Cut Edge Corrosion Treatment

by Rooflock

Rooflock Twelve is a BBA certified, liquid applied roof waterproofing system for pitched steel roofs.
It is widely specified for the protection of corroded metal roof sheets, in particular cut edge corrosion.
Applied directly to corrosion affected lap joints as an external seal, it has a strong adhesion to most metal roof coatings. With its high elasticity and flexibility, it

withstands sheet movement and is unaffected by extremes of temperature.
Applied by a network of approved contractors, Rooflock Twelve is a very cost-effective method of extending the life of the roof with little disruption.

What is cut edge corrosion?

Cut Edge Corrosion is the term given to corrosion that develops at the cut edges of a steel roof sheet. It can develop from poorly coated machined edges of the metal

sheets, or by breakdown of the original lap sealants, allowing water to be retained between the roof sheets. As the steel begins to corrode, the original coating peels

off and water is further retained between the roof sheets, exacerbating the corrosion further.
If unchecked, cut edge corrosion can progress to become a serious problem affecting both the weatherproofing and structural integrity of the roof. By addressing this

issue early with application of a dedicated metal protection product such as Rooflock Cut Edge Corrosion System, potentially costly and disruptive remedial action

can be avoided.
