Single- and double-module metal roof tiles: which differences matter?
What matters is not the number of modules itself but the covering area of a specific panel. Before comparing, check the product dimensions and the cut plan on the actual roof slope, including the ridge, eaves and obstacles. A module is a repeating section of the pattern along the slope; overall length also includes the parts needed for joining, so it is not equal to the covering length. The format affects handling, the number of joints and the fit of edge rows, but it does not by itself determine steel quality or coating durability. The choice should be driven by roof geometry and installation organisation, not by the label ‘single-’ or ‘double-module’.
