Substructures for metal roofs must be designed, as far as possible, with a >7° (13%) roof slope. This is the initial value to guarantee relative security regarding gradients and inflections of the substructure. The minimum tolerated slope is 3° (5.2 %). Only in exceptional cases are zintek® roof coverings recommended for slopes from 3–7°, consult manufacturer for details.
