Step 16 Install Roof Sheathing
1.
Starting at the rear of the building, install 4x8 OSB roof panels and 1x6-8' white pine
fascia boards on each side. Install the roof sheathing and the 1x6 fascia boards flush with
the face of the siding on the back gable. Install the fascia so the bottom edge of the roof
sheathing will rest on the 1x6. See detail below.
Make sure the trusses are plumb and the roof sheathing meets the center of the truss.
Use 7d sinkers spaced 12" apart. Cut a 6' long sheet for the top row. If you are installing
ridge vent, cut the roof sheathing about 1" below the ridge to allow for ventilation.
