Roof mounted mast support

A device for mounting a structure to the roof of a building, said device comprising:

• a base plate removably secured to the building roof, said base plate having an upper planar surface and a lower planar surface;
• a standoff comprising an elongated housing which extends outwardly away from said roof and presents a bottom planar surface being removably secured to said roof, a top planar surface parallel to and remote from said bottom planar surface;
• a mounting plate presenting a radially extending planar mounting surface said mounting surface being parallel to and spaced from said top planar surface and further being removably secured to said top planar surface;
• at least one gusset fixedly attached to said structure and extending radially therefrom, said gusset further being fixedly attached to said mounting plate;
• an upper housing extension that projects upwardly from said mounting plate;
• wherein said mounting surface and said top planar surface are adapted to receive a first locking device for removably securing said mounting surface to said top planar surface;
• and
• wherein said roof, said base plate, and said bottom planar surface are adapted to receive a second locking device.
