I have a zinc roof, shallow pitch and not galvanised but just zinc sheets> It has after only 18 months got holes in it with white dust in place of what was the zinc! What could be repsonsible for such aggressive wear of the zinc?		MAtt Lewis What is a tag? 5/23/2008	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/11478/find/
Is it trapping moisture behind the zinc? That can cause rapid deterioration of rolled zinc.		Todd Miller Isaiah Industries, Inc. 5/24/2008	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/11479/find/
