A deck post (or brace) having a non-circular cross-section is secured to a roof deck. A lead pipe jack (sleeve) is slid over the post. A waterproofing assembly having a collar and a skirt is provided; the collar has an opening with generally the same non-circular cross-section as that of the post. The collar opening is positioned on the deck post, and the unit is slid down the post until the collar is at the top of the sleeve, the skirt extending down over the sleeve. A clamp is then positioned and tightened around the collar to provide a watertight seal on the deck post. When the post is already installed on a roof deck and the sleeve and the waterproofing assembly cannot be slid into place on the post, a modified retrofit waterproofing assembly and sleeve are used to provide the waterproofing. The modified sleeve is a split lead flashing jack with an open seam on one side. The sleeve is opened up, wrapped around the post and soldered closed. The modified waterproofing assembly has a split joint through the skirt and collar. To position this assembly on the post at the top of the split lead flashing jack, the joint is opened up, the assembly wrapped around the post and the slip joint closed with a watertight flap. A locking closure can be provided having a locking clasp and a locking slot. Another alternative waterproofing assembly forms the collar as a plug separate from the skirt; the skirt is opened and the plug inserted therein. This arrangement allows a plug having the desired opening configuration to be selected from an inventory of different plugs and used with a single skirt design. Another alternative of the waterproofing assembly provides a series of flanged tabs on the top edge of the collar for connecting to the collar plug. The flanged tabs may each have a projection on them which increases the pull-out resistance between a connected skirt and collar. The collar plug may also have a series of cavities which line up with the flanged tabs of the skirt. The collar plug may have a recess for the clamp. As an alternative assembly, multiple skirts can be connected together using their locking clasps and locking slots and the resulting larger skirt can then be connected to a collar.
