Ridging End-Closure

Roll-top End Cap

Roll Top End Cap

The gable end termination of roll ridging must be made vermin-proof by cutting the ridging and closing.

An alternative to continuous ridging on ribbed profiled sheets is using individual rib or ridge caps, fitted to each rib after the ribs have been cut and the roof cladding bent over the ridge. Each cap should be accurately fitted and sealed.  This method does not allow for free expansion at the ridge of long length roof cladding or for ventilation at the apex.

One-piece ridge caps, such as Canterbury prickles or shark's teeth, are the preferred caps. All caps rely on sealant to be made watertight.
