Historic church's copper roof good after 213 years
Examination of roof of Christ Church, Philadelphia, shows weathering loss equivalent to corrosion rate of 0.000033 in. per yr; higher rates reported to have been shown by recent corrosion tests on copper sheets in industrial atmosphere; difference may be explained by relatively unpolluted atmosphere in Philadelphia during initial service of roof.
