Slope length5,20 m

Ridge (trim elements)10,00 m

Battens (0.35 m spacing)358,00 m

Membranes — net area +10% for overlaps. Soffits — by house perimeter.

Slope area = span/cos(pitch). At 30° the roof exceeds the footprint by ~15%, at 45° — by 41%. Minimum pitches: metal tile 14°, profiled sheet 8°, soft shingle 12°, natural tile 22°. For metal tile also count the effective sheet width (≈1.1 m).
