Abstract:
1. A building roof monitoring system comprising: a fiber optic filament positioned between a water barrier layer and a roof substrate layer of a building roof; a water transport layer in contact with the fiber optic filament having a weave spacing sufficiently large to allow roof adhesive to pass through the water transport layer to adhere the water barrier layer positioned above the water transport layer to the roof substrate layer positioned below the water transport layer; an optical analyzer for injecting laser light into the fiber optic filament and detecting a change in propagation of the laser light through the fiber optic filament indicative of water coming in contact with the fiber optic filament to detect a roof leak; a response system comprising a controller, alarm or remote communication unit operatively connected to the optical analyzer configured to respond to the roof leak detected by the optical analyzer.
