I've been trying to find a solution for insulating my attic, and have so far received all kinds of different answers. I have a 1950's or 60's home with original batt insulation in the attic that has settled down and is basically useless. I live in upstate NY, and have had very significant problems with ice damming - all the snow melts from the peak of the roof down, freezing in huge sheets along the eaves. I am planning to install blown-in cellulose to R50, but am unsure what to do about the inaccessible areas above the "semi-cathedral" ceilings on the second floor (see attached sketch). There are existing baffles, but I'm unsure what, if any, insulation is down between the rafters (it does seem to stay cooler along the bottom of the roof). The house has soffit vents, ridge vents, and gable vents. I am having a new roof installed this spring.
Any advice? For some reason nobody seems to have seen a house like mine in this area. :rolleyes:
