The batten roll method is the oldest of the traditional techniques and is particularly suited to rehabilitation projects.
This method consists of joining the strips by interposing a timber batten in the direction of the slope.
In this system, weathertightness between the steel strips is provided by a capping covering the timber battens.
This capping provides the roof with its characteristic wide-joint appearance.
This technique may just as well be used on warm or cold roofing systems.
