The choice of modular metal roofing for a mountain-style roof depends first on the pitch of the slopes and the project requirements, and only then on the embossing pattern, colour and coating. It is worth checking how the modules are laid out around dormers, valleys and chimneys, and whether a sample confirms the expected texture and shade. Where there are numerous breaks, the possibility of reusing cut-off pieces also matters. Leave the final choice to the designer, who will account for loads and fixing.

The choice of roofing for a mansard roof depends primarily on the permissible pitches, the fixing method and the details, not on the material alone. Each slope has an upper and a lower part, so the covering must suit both and the break line. Modular metal roofing simplifies work on complex geometry, while cut-to-length sheets work well on simple sections. Before deciding, check the cross-section with actual angles and lengths, the model's approval for both pitches, and the continuity of ventilation and insulation.
