I just moved into a new home where the builder installed R-30 in the ceiling truss area. I had requested R-30 as a minimum. After looking at their work, the electrical wiring is woven in and out of the insulation to where we probably only have R-11 or less in several locations. You can tell by the snow melt on the roof that it is poorly insulated too. What is the best way at this point to improve this situation? But you know I think they might have saved them selves a few bucks on their wire material!
