A standard minimum for a sheet of metal placed on the roof so that it overhangs the edge is at least of an inch to 1 inch 2 2 5cm.
On the other hand a maximum is around 8 11 inches 20 30cm.
Oil canning in metal roofing is an observed waviness or buckling across the flat areas of sheet metal panels that does not normally affect the roof s structural integrity.
In fact if you re building a house or an addition you can often downsize or reduce the number of roof support members.
