Water distributing apparatus for uniformly wetting a roof to provide evaporative cooling. The apparatus includes a generally horizontal water conduit supported on a roof, a flexible tube attached to an upper surface of the conduit and a directional nozzle attached to a second end of the flexible tube. The directional nozzle has an outlet angularly displaced from the longitudinal axis of the second end of the flexible tube to provide rapid generally random movement of the nozzle about its point of attachment to the water supply conduit. In one preferred embodiment the conduit includes spaced apart conduit tee components having upstanding branches into which are fitted plugs supporting connector fittings for the flexible tubes. A filter screen is mounted in each of the plugs. An upstanding sleeve surrounds the tube connector fitting and is operable to engage the flexible tube to minimize snagging of the directional nozzle under the edges of the roof shingles and control the flailing action of the tubes.
