We are having a new house built. The builder has been working on another house and the insulation he used was soaked in an uexpected rain storm. He pulled the insulation and was drying it out in his workshop. We're concerned that once the insulation is dried out he will use it in our new house. Can wet insulation be dried out and reused without any future problems? What actions should we take to ensure we have no problems with this insulation.

Hello, I'm going to have my roof (4/12 pitch cathedral ceiling) in Vermont replaced soon and the latest proposal from a roofer is to remove everything from the existing 2X6 tongue and groove ceiling/decking and put down Typar RoofWrap 30 underlayment, then 4 inches of ISO foam board, then 1/2 inch OSB plywood directly over the insulation, then standing seam roofing over that (Kynar-500 coated galvalume, coil fabricated 24 guage, 1 inch high seam profile, double lock mechanical seam). No ventilation. I currently have 2 inches of rigid foil wrapped foam with asphalt shingles on top. My questions are these: 1. Is unvented OK since it's standing seam? 2. How much different will my energy bills be with the extra 2 inches of foam? Right now in the winter with heat source in lower floor, there's a 10 degree variation between up and downstairs. it get much warmer upstairs? How do I figure this out? I have been offered a less expensive option of just roofing over the existing insulation without adding more. Should I not bother to add insulation? Thanks CT
