The house is a 1942 cape cod, in Ohio. Roof hits external walls with no overhang. Currently, the attic has a bedroom carved out of it, leaving two triangular-shaped storage areas to it's left and right. There's also a triangle above the bedroom (under the peak of the roof), but I have no idea what's there. There are gable-end vents (they probably open into the "triangle" above the bedroom and below the peak).
The storage areas seem insulated ok, though the fiberglass is mixed with a lot of dust, random little crap, and a lot of mouse droppings (the flooring nailed over the fiberglass is rather sub-par) The fiberglass covers the roof side, the bedroom wall, and the floor. In most places they're continuous rolls (it starts being on the floor, moves up the inside of the roof and finishes on the bedroom wall.
The roof is about to be changed. The roofing company wants to install a ridgetop vent (I'm for that), and also install these funny metal dealies that will basically add a soffit vent above my gutters.
The roofing guy swears this will work.
Will that actually work?
Is there a problem with there not being a gap, as such, in the insulation at the joing between the roof and the exterior walls?
How would one optimally insulate these spaces?
