I have a 1940s Cape Cod house and we are having severe heat issues with our upstairs.

There are no soffits or ridge vents, only 8 box vents near the top. Currently, there is R-19 fiberglass going up the roof slant. However, the floor joists (above the downstairs ceiling) and the vertical knee walls are completely uninsulated and bare.

I live in a mixed/four-season climate. Because there is no low-eave ventilation intake, what would you recommend? Should I pull the R-19 down to insulate the floor/knee walls instead, or look into an unvented hot roof setup?
