Truss roof with multiple hips/valleys soffit to roof vents
Hi all. I have been reading some of the roof venting strategies and have not yet figured out my answer. We are in the middle of building our new home which was constructed with trusses for a multiple hip (courtyard in a ranch style house) roof.
The question is this – I am going to use about 24 inches minimum blown-in cellulose for about an R-60 or better rating, but I am not yet sure about using soffit to open space (ridge vented) pass through structures. Since my entire ridge line will be vented, and the soffits will also be vented, what is the reason or do I need to put in air paths from the soffits to the upper truss area?
The R60+ blown in insulation and superior sealing of the home should keep any moisture/heat escape to almost none so what is the reasoning for soffit to roof ventilation in my situation?
thanks all in advance.
