Picking up where you leave off after nicking a finger on a table saw is a bit of a sketchy proposition, but the work has to get done, and the only way to do that is to get right back on that horse and ride, ride, ride.
After finishing the milling process (exactly one week after the table saw incident) for the various treated roof framing pieces that go together to make the 1/4" per foot sloped roof decking and the mini-parapet that presents a clean fascia to the roof overhangs, and getting all of that screwed down to the SIPs, it came time for much super-human lifting. 3/4" tongue and groove plywood decking had to be lifted up to the roof in order to create the required slope over the tapered sleepers at 24" o.c. I swear, the Egyptians never had it so hard... And doing it in full sun on a 100˚ day made it all the more exhausting, but we got it done all done in a day and a half.
You can plainly see the tapered 2x6 pieces that define the needed slope, as well as the 2x6 parapet beyond that hides the slope from view. After a much needed weekend the roofers showed up to install the actual finished roof surface.
For a roof of such minimal slope, the obvious type of roofing to pick is a membrane roof. The lightBOX is capped off with a fully adhered single-ply TPO roof. Contact cement is applied directly to the plywood decking and to the underside of the membrane roll, and then rolled into place in the field of the roof. After the membrane boundaries are screwed down to prevent any uplift the parapet is stripped in with narrower strips of membrane material to turn up the sides of the parapet and to cover the mechanical fasteners of the membrane boundary. Once all of that is finished all of the seams are heat welded to accomplish the final waterproof surface. The vent boot is also heat-welded to the TPO surface to make that waterproof as well. The final step will be the installation of custom metal fascia flashing to cap the eaves of the roof and the top of the siding. This flashing will be installed after the wall siding is installed.
The housewrap was applied over the wall panels in preparation for window installation and the the 1/2" furring strips required to properly install the snap-lock paint-grip metals siding. The bathroom window was set as well. Now we are just waiting on the imminent arrival of our fixed clerestory windows and the installation of the furring strips before we jump into having the siding installed. The exterior is really close to being wrapped up.
