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. From there the method used to fix a particular leak depends on the cause.

Spray testing is the use of controlled water flow deposited on building components in a manner that simulates normal to severe weather conditions. Breaches are found by detecting a water path to building ground. Fixing leaks in a corrugated metal roof starts with locating the source of the leaks.

Per foot i e.

1 1 this test method covers the determination of the resistance of exterior metal roof panel systems to water penetration when water is applied to the outdoor face simultaneously with a static air pressure at the outdoor face higher than the pressure at the indoor face that is positive pressure.
