09/20/2022 KEN VAN KARSEN BUILDING-RESIDENTIAL REVIEW Reqs Change An unvented roof assembly requires an air-impermeable rigid insulation material with a minimum R-5 value applied correctly to either side of the roof sheathing, R806.5. Show a roof design with insulation types and minimum thickness for meeting the condensation control requirement and the minimum total insulation value of R-38. Update sheet #4 & 6 for consistancy with #13 & 17.

Please clarify the unvented ceiling insulation with 2018 IRC code compliance. Batt against the roof deck is not an option. Either show R-38 spray foam or a 2-layer system of a minimum of R-5 foam board (or spray) against the roof deck with R-30 batt in contact with the foam. The first method is expensive so the less costly 2-layer method is common.
