Round two of building the roof began by putting up the front porch beam. We used scaffolding to support it temporarily so that we could make minor adjustments and level it more easily. Once we were satisfied with the beam’s placement, we secured it with some additional temporary supports and ran three strings from the ridge to batter boards on the ground to get the slope right. After all the strings checked out alright, we nailed the precut porch rafters to the front knee wall and fixed them to the beam with hurricane ties.
Next we installed the columns. With scaffolding still in place, we built the 4-ply, 2-by columns around the beam and, using off-the-shelf L-brackets, marked on the slab where to hammer drill holes to connect the brackets to the concrete. We drilled the holes, filled them with epoxy, and mucked in threaded rod. Once the epoxy set, we securely tied the columns, metal footings, and slab together with washers and nuts. We also installed the horizontal supports for the benches in the outer bays. We similarly installed the back beam, column, and rafters after the front porch was done. Once all the roof rafters were up, we sheathed the roof in OSB and tar paper.
