What is the minimum pitch for a zinc roof?
3 degrees
SIG Zinc and Copper recommend that the minimum pitch for a standing seam zinc roof is five degrees, with an absolute minimum of 3 degrees. We recommend 5 degrees, however, due to site conditions and execution. A 3-degree roof pitch means just over 50mm in every metre, so over 3 metres you only have 150mm to play with.
