ABSTRACT:
A moisture intrusion detection system is provided, wherein a plurality of independent and insular moisture detecting units are placed in a predetermined spaced apart relationship across the surface of a roof structure, or other system incorporating a water impermeable membrane, beneath the water impermeable membrane thereof. Each of the detecting units includes a moisture detecting and power supply unit and signalling unit. When moisture penetrates the water impermeable membrane of the roof structure, a leak condition exists and a water activated battery is activated. Each detecting unit in contact with water is activated. In combination with the detecting units, position and direction locator apparatus are used in combination with the detecting units to localize the source of the leak and the extent of any water damage caused thereby.
