Is the contractor right?
My home is a 1 1/2 story (?) 1300 sq ft home. Upstairs on both sides of the house the ceiling slopes down (where the roof is). I asked a contractor friend about insulating the attic (he would have to first open the ceiling to allow attic access- there currently is none) and he said in order to insulate properly the ceiling would have to come down and would have to be re-built. He said this is due to the fact that the roofing would rot if insulation were stuffed in the space and the roof not allowed to breathe. Does this sound right? I was just going to open the access and blow in cellulose. (cheap and easy) Will the cellulose make any difference in heating, or would it cost me a roof?
