Designed for modern low-pitch applications, the Level RS system performs reliably on roof pitches as low as 10° , supporting rafter lengths of up to 10 metres. Engineered for durability and reliability, the Level RS features deep interlocking joints on all sides, incorporating triple head and side interlocks. This sophisticated system enhances weather resistance, prevents damage from wind uplift, and provides exceptional long-term protection in the toughest environments.

Recognised internationally for its excellence, the Level RS is the proud recipient of both the iF Design Award. This prestigious accolades reflect its outstanding combination of form, function, and innovation.

Low Pitch Specification

For verge to verge and lean to roofs with Rafter pitches between 10° - 16°, and a maximum rafter length of 10 metres.
The roof structure should be fully boarded using suitable timber decking. A continuous layer of Stoneleaf Sovereign 330g/m2 underlay installed over the decking, with all laps sealed using the integrated tape.
Install Counter battens 38×50mm, vertically over the underlay at centres not exceeding 600 mm. Counter battens to be installed over a self-sealing tape ensuring all fixings are sealed against water ingress.
Tile battens of 25×50mm are then be fixed horizontally to the counter battens in accordance with the required gauge for Level RS tiles, ensuring that each tile is securely clipped.
