There is disclosed a sprinkler apparatus which may be coupled to an exterior roof of a building, typically a house, in order to provide fire suppression for the exterior of the building. The sprinkler apparatus can substantially withstand the radiant heat from nearby fires. It may be crafted as a single, seamless, unobtrusive unit having a telescoping active sprinkler body that can rotate a full 360 degrees. Further, the sprinkler apparatus may be coupled to an external roof of a building in such a fashion that the longitudinal axis of the sprinkler body forms substantially a 90-degree angle to the plane of the roof.
