Marley Type A brown batten: preservative brown treated to Use Class 2. Marley states explicitly that it is NOT suitable for BS 5534 applications and that JB Red is the graded batten to use for roofing. This is the distinction that decides whether a batten is legal to tile onto, and it is not visible on site once fitted.

Marley Universal 10mm Roof Eaves Ventilation System provides a continuous 10mm free vent area to the roof void, sized for lower pitched roofs with deeper insulation. It compresses the insulation at the eaves to preserve airflow, allows clip fixing of all tiles at the eaves, and prevents ponding on the underlay behind the fascia board and wildlife ingress. Meets BS 5534 requirements and NHBC guidelines. Fascia or tilting fillet height must be checked against the tile type and rafter pitch, allowing for the over-fascia ventilator and comb filler strip.

Marley western red cedar shingles: 400mm long with random widths 75mm to 350mm, 10mm thick at the butt tapering, minimum pitch 14 degrees, fixed to 38mm battens. Gauge, coverage and laid weight change sharply with pitch. At 75-90 degrees (vertical cladding) maximum gauge 175mm, 3.20 m2 covered per bundle, laid weight 4.0 kg/m2, 5.3 lin.m/m2 of battens. At 22-74 degrees maximum gauge 125mm, 2.28 m2 per bundle, 6.1 kg/m2, 8.0 lin.m/m2 of battens. At 14-21 degrees maximum gauge 95mm, only 1.73 m2 per bundle, 8.1 kg/m2, 10.5 lin.m/m2 of battens. Dropping from a 30 degree roof to a 15 degree roof therefore costs roughly a third more shingles and battens.
