An adjustable roof drain has an extension and a base ring. An adjusting mechanism on an inner surface of the extension engages an adjusting mechanism on an outer surface of the base ring to adjustably set the position of the extension relative to the base ring. Preferably the adjusting mechanisms are threaded connections. A bead of sealant may be placed in a groove that is exposed at the joint between the two parts after the position is set.
