No 1 Roofing & Building Supplies are the premier manufacturer and stockist of Snap Lock Roofing and Cladding products,


Snap Lock is a lightweight architectural cladding system ideal for both roof and wall applications in commercial, industrial and residential environments. Its thin distinctive ribs and wide pans give it visual appeal.

Snap Lock looks similar to Standing seam without the need of crimping the joints due to the “snapping” process. Available in 25mm and 38mm ribs, Snap Lock can be manufactured in various widths to suit new construction or renovation projects.

Snap Lock Technical Specification

The support needs to be ventilated, rigid and continuous where all parts of the Snap Lock panels are laid. The plywood minimum thickness shall be 15mm for cladding and 18mm for roofing. Snap Lock panels are laid directly over the ply substrate and held in place with a concealed clip.

Clips are fixed with countersunk screws onto the timber supports at maximum 600mm centres. Each panel has a male and female rib. The female rib is held in place by a clip.

The male rib is placed over both the clip and female rib. Material choice to be verified by client and installation must comply in accordance with the BCA.
