Hi Jon,
I thought I would look up and add the following from the SSTD 10-99 (the 1999 version).
The following is from wood framed exterior wall section.
- 307.3 Bracing
- - 307.3.1 When a gable endwall extends from the uppermost floor to the roof sheathing and is not supported by a ceiling diaphragm, andwall roof bracing shall be provided perpendicular to the rafters or trusses in the first two rafter or truss spaces at each end and shall be spaced at 4 ft maximum on center as shown in Figure 307F. Bracing members shall be full depth of rafters or truss top chords. Roof sheathing shall be attached to bracing with panel-end nailing recommendations.
Figure 307 simply shows the bracing at the top chords or rafters going back the first two rafter/truss spaces, the roof sheathing would have been nailed through to these braces. These braces are *not* diagonal or 'X' bracing, just lateral bracing at the top chord.
