Methods for detection of the presence or absence of water leaks in building roofs and for tracing any leaks to the zone or area thereof in the roof by applying on all or part of the roof fluorescent dye-containing water, shining a fluorescence-inducing light, e.g., actinic or U/V light, onto the underside of the roof, its support structures, roof-penetrating structures and/or surfaces of walls beneath the roof, tracing the path or paths of fluorescence (if present) along the underside of said roof, and/or roof-penetrating structures, and/or roof support structures, and/or the building wall(s) to or near the point of origin of the area or zone of water leakage through said roof, and optionally applying the fluorescent dye-containing water onto the roof in the form of a spray in a fast-moving air stream or as a water jet or jet-spray to simulate wind-driven rain.

A method for detection of an area or zone of water leakage through the roof of a walled or unwalled building, which comprises applying on all or part of a roof known to have, or suspected of having, water leakage therethrough a sufficient amount of water, having a fluorescent dye dissolved or dispersed therein, to cause said dye-containing water to flow through a roof leak point or zone onto the underside of the roof, and/or roof-penetrating structures, and/or roof support structures and/or the walls of the building beneath the roof, said fluorescent dye-containing water being applied in the form of a spray in a stream of air moving at a velocity of at least about 20 miles per hour; thereafter shining onto the underside of said roof, and/or said roof-penetrating structures, and/or said support structures and/or surfaces of walls of the building a light having a frequency band or spectrum which induces said dye to fluoresce; and tracing the path of fluorescence along the underside of said roof, and/or roof-penetrating structures, and/or roof support structures and/or the building wall to or near the point of origin of the area or zone of water leakage through said roof.
