Standing-seam metal roofing with a groove spacing of 6.3 mm. At a factor of seventy-two the joint works out at four hundred and fifty millimeters, at a factor of eighty-seven at five hundred and fifty.

A sheet 15 x 30 cm with the lengthwise pattern of standing metal joints. The groove spacing is 6.3 mm, which is a third more than on the finest variant of this group of four.
With the previous spacing it makes sense to count from the sheet to the building. Here it pays to reverse the direction and start at the model. Say you are building in 1:72 and want seams every five hundred millimeters. Five hundred divided by seventy-two works out at seven millimeters, so you are looking for a sheet somewhere around that value. A spacing of 6.3 mm corresponds in the same reduction to a joint every four hundred and fifty-four millimeters, which is inside the real range and nobody will notice the difference from the ideal.
What is more interesting is that the same sheet also stands up some way further off. In 1:87 the spacing works out at five hundred and fifty millimeters, that is, credible roofing again. One sheet thus covers two usual reductions without looking out of place in either. That does not happen often with textured surfaces and it is why this spacing in particular tends to be the first choice for shelters and halls.
On the finished roof do not forget the ridge and the flashing at the chimney; these are not on the sheet and are added from strips of thin plastic. Without them the surface looks like an unfinished panel.
Deal with a roof light or a hatch by cutting the opening along two neighboring grooves and edging it with thin plastic. A cut led across the pattern is visible at first glance, whereas a cut along a seam merges with the surface. The same rule applies to the hip of a hipped roof, where two parts meet at an angle: miter them and run a narrow edging over the joint, which on a real building corresponds to the capping metal.
