   Standing seam metal roofs can have a lower pitch than asphalt shingle roofs because shingled roofs need a higher pitch to keep the wind from blowing up the shingles and potentially blowing them off in high winds. Standing seam metal roofs come in sheets up to or sometimes more than 30 feet (9.1 m) long and widths of 12, 14, 16 or 18 inches (300 ...

   A study by Ducker International in 2005 identified the average cost per year of a metal roof to be US$3.2 per square metre ($0.30/sq ft) while single-ply roofs stood at $6.1/m 2 ($0.57/sq ft) and built-up roofing at $4.0/m 2 ($0.37/sq ft). [25] Metal roofs are also one of the most environmentally sound roofing options, with most metal roofing ...
