A multi-pitched roof is a form with several connected slopes, and the choice of covering depends primarily on the geometry and sheet layout rather than on the name alone. Check the detailed drawing of ridges, hips and valleys, along with a cutting plan for the sheets, to assess waste and how details will be formed. For metal roof tiles, T18 or T35, analyse the pitch of each slope, ventilation continuity and drainage. The suitability of a given format should be decided by a full schedule of material and works, left to the designer.

Before choosing a covering, decide whether the cabin will be used only in summer or also in winter — this is the first question before making a decision. The answer affects the layer arrangement, ventilation and the risk of condensation. Check whether a simple T18 or T35 trapezoidal profile suits the structure, and whether a modular metal tile suits a more residential form. Consider rain noise, pitch, batten spacing and site access. Remember that the metal sheet alone does not solve temperature and moisture issues.

A modern roof look is determined by the coherence of the building's form, roof slopes and façade, not by one specific profile or a mandatory black colour. Before ordering material, check how your chosen variant appears when seen from across the street. Deep profiles and broad flashings read differently on a small house, while a delicate texture may disappear on an expansive slope. Compare the sheet layout, the position of laps and cuts, and the availability of accessories. Remember that appearance must be combined with the requirements for pitch, ventilation and structure, and that attic comfort also depends on thermal insulation.
