Laying sheets

Sheets can be laid left to right or right to left*. Sheets should be laid perpendicular to and starting at the eaves. Don’t forget to leave an overhang to go into the gutter or beyond the wall plate (usually 50mm (2”) is sufficient.

* Please be aware that tile effect sheets can only be laid one way Brit-Tile is left to right lay, Flow and Wave Tile is right to left lay. This is due to the gutter detail and, in the case of Flow-Tile and Wave-Tile profiles, the capillary groove for side laps. 

Quick tip prevailing wind

When laying sheets on an apex roof (double sided) remember to leave a gap of approx. 2” (50mm) at the ridge (tip of the apex). Also, if you are using profiled g.r.p rooflights on an apex roof and wish to keep them in the same position on both sides you will have to lay right to left on one side and left to right on the other. (Tile effect sheets do not have profiled rooflights available)

Below we have provided numbered diagrams showing you a recommended lay pattern for each direction of lay.

Alternative lay patterns may be used depending on the profile of the sheet being fitted. If you are unsure about lay patterns please speak to a qualified roofer or contact our technical team before attempting to lay and fix the cladding as mistakes made at this point could result in the need to order additional sheets.
