Fixing leaks in a corrugated metal roof starts with locating the source of the leaks. Breaches are found by detecting a water path to building ground.

The roof test standards are astm e1680 standard test method for rate of air leakage through exterior metal roof panel systems and astm e1646 standard test method for water penetration of exterior metal roof panel systems by uniform static air pressure difference. The integriscan is a low voltage quality control test that pinpoints breaches in roofing or waterproofing assemblies. Superior electronic leak detection testing for vertical horizontal waterproofing roofing membranes including black epdm. Flood testing to detect leaks and verify the quality of newly installed assemblies has a long history in the roofing industry.
