As a general guide, in non cyclonic areas, for every 1m2 of roof area drained, 70mm2 of downpipe is required. This calculation is based on the assumption that the maximum rainfall does not exceed 125mm per hour.

It is considered the best practice to drain to different points, using smaller downpipes rather than to one large outlet. Where possible, downpipes should be spaced at not more than 12000mm centres.

For a more accurate guide, consult the Installation Code for Metal Roofing and Wall Cladding SAA HB39-1997.
