ABSTRACT:
A method and apparatus for fastening an object, such as a board to which another object may be fastened, to a clay tile roof utilizes rod threaded at both ends with a wing expansion nut on one end that is passed through a hole drilled in the tile and supporting wood at a wing point where the tile rests on the wood. A rubber washer backed by a metal washer and nut seals the hole in the clay tile and secures the rod in an upright position. A washer and second nut at the other end of the rod then secures the object to the roof with the object spanning the ridge points of two or more tiles. A third nut locks the second nut on the rod, and allows the rod to be turned like a bolt to drive the excess rod into the roof. To facilitate installation, the rod is preferrably threaded from end to end.
