Angled bird blocks seem to be the norm around here (Western Washington) however vertical blocking inline with the ext. wall framing seems to be the more acceptable and approved method. A max. 2" space is usually allowed for venting purposes however as a structural engineer I like to see full height blocking to the roof sheathing/diaphragm especially over shearwalls or braced wall lines.
I can probably provide two to three option for blocking once I have arrived at a consensus on what is the most popular method(s) for blocking at the truss heel. Please feel free to chime in with suggestions or preferences in this regard.
