Step 28
Install 2x8 Ridge Beam
1. Cut a 2x8 board to a length of 140-1/2" and install as a ridge beam into the slots
of the dormer trusses.
2. Secure the ends of the 2x8 with a metal joist hanger and 10d coated sinker nails.
3. Layout where the 2x6 rafters will be installed on the ridge beam; see below.
4. On both dormer walls, layout where the 2x6 rafters will be installed; see below. Install H1
hangers where the rafters will be placed over the 'X' marks. Use 6d common nails to nail the
hangers to the truss plate. When the rafter is set (next step), use a 1-1/4" screw on each side
of the hanger, and toenail the rafter to the truss plate using 10d coated sinker nails.
