Unvented cathedral eave/soffit insulation?
Is it correct that roof overhangs should be insulated due to the potential for warm air (heated by solar energy on the wall of the house) to rise up and cause ice dams on an uninsulated roof overhang?
Based on the attached diagrams, I am wondering about the regular 2′ overhangs, as well as about the boxed-in void areas above the 6′ covered walkways on some sides of the house.
Climate Zone: 6B
Unvented cathedral ceiling/roof assembly
What advice do you have for me on this?
