Drill lookout framing for soffit ventilation?
I’m currently installing insulation baffles in a mostly new build (kept old basement, but completely gutted main floor and added 2nd story).
I’ve attached some pictures to help explain.
We have some fairly standard raised heel roof trusses, soffit & ridge peak venting, and 2 foot overhangs at the eaves and gable ends. To support the wide overhangs, the trusses have “lookouts” (see diagram-1). The lookouts are fine, but block the airflow from the soffits (see diagram-2). This is only a problem in the corners of the roof. Everywhere else, I’m venting with a 2″ air channel (diagram-3).
How do greenish builders vent in the corners with the lookouts in the way? I’m currently thinking of drilling a few 1/2″ holes in each lookout to allow for a bit of air flow.
I’m in chilly Winnipeg Manitoba Canada.
Thanks for your help.
