Abstract:
An apparatus for detecting leaks in a metal roof having a plurality of metal roof panels which are secured in position to form a roof structure by mechanical fastening elements, the apparatus comprising:an elongate tubular stand having a lower extent and an upper extent connected by an internal bore, the lower extent terminating in a bore end opening; pressurization means communicating with the internal bore for supplying positive pressure or drawing a vacuum on the internal bore; seal means located within the bore end opening for forming a pressure tight seal about a selected one of the mechanical fastening elements used to secure the metal roof panels; gauge means communicating with the internal bore for measuring a change in pressure within the internal bore, such pressure change being indicative of a leak present at the mechanical fastening element being tested; wherein the gauge means includes a pressure gauge located on the exterior of the tubular stand, the gauge being observable by a user during operation of the hand pump; and a check valve located in the tubular bore between the piston element of the hand operated pump and the pressure gauge.
