Step 15 Install Roof Sheathing
1.
Starting at the rear of the building, install 4'x6' OSB roof panels and 1x6-6' 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. Use 8d galv. nails.
Make sure the trusses are plumb and the roof sheathing meets the center of the truss.
Use 7d sinkers spaced 12" apart. The upper roof sheathing will be about 1" below the
ridge to allow for ventilation.
