Adapting Josh Salinger’s Roof Assembly
I like the look of the roof design in Josh Salinger’s article “a new take on insulating a roof” in issue 299 of Fine Homebuilding. I’m wondering whether the basic approach would translate to a my zone (northern Maine, 7a) by using a parallel chord truss sized to allow for ~2 feet of cellulose to get to R-80. Would it need changes such as increased the strapping or using sheathing to support the additional weight of the cellulose, or perhaps different barriers/membranes because of our climate? Are there examples of similar roof structures available online?
