A deck post (or brace) having a non-circular cross-section is secured in place by bolting its mounting bracket to the roof deck. A lead pipe jack is slid over the post, and its lower flange is nailed to the deck. 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 lead pipe jack and the skirt extends down over it. A stainless steel hose 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 jack and the waterproofing assembly cannot be slid into place on the post, a modified waterproofing assembly and jack are used to provide the waterproofing. The modified jack is a prior art split lead flashing jack with an open seam on one side. The jack 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 snap-fit closure can be provided. A further 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.
