Watertight system for mounting equipment on roof

A watertight mounting system for mounting objects above a roof deck, said watertight mounting system comprising:

• a) a deck mount having a flat plate for fastening said deck mount to the roof deck, and a coupling joint with an insertion opening pointing away from the roof deck;
• b) an elongate joining member having a top end and a bottom end, said bottom end being fitted into said insertion opening, thereby orienting said elongate joining member away from the roof deck;
• c) a top U-channel for grasping an object framework, said object framework upholding the object above said roof deck, said top U-channel having a cap swivelably mounted in said top U-channel for attaching said top U-channel on said top end of said elongate joining member and thereby allowing to adjust said object framework parallel to the horizontal;
• d) a bottom U-channel, said bottom U-channel and said top U-channel being joined by their bases with an elevator bolt;
• and
• e) a flashing for tightly enveloping the lower portion of said elongate joining member to produce a watertight seal around said elongate joining member, said flashing extending downward to cover said deck mount and being fastened to said roof deck, thereby providing a watertight seal to said roof deck.
