Pitch is at or near the minimum

Low-pitch roofs need more flashing cover, more care at side laps, and a drainage check. Confirm as-laid pitch after deflection.

Cladding pitch is not design pitch

NZMRM CoP 7.1.1A: tabulated minimums are roof cladding pitch, not the building-design roof pitch. Wide purlin or portal spacing can leave the as-laid pitch below the table even when the drawings say otherwise.

This is a takeoff, not a quote

Numbers assume rectangular planes, constant pitch, sheets laid ridge-to-eave, and published nominal cover widths. Hips, valleys, penetrations, stop-ends, and end laps change the order. Confirm on the current product sheet and the latest CoP at metalroofing.org.nz.
