I am contracting a roofer to install a steel shingle roof on a three story Victorian in Iowa. All but about 15% of the roof has plaster and wood lath on the other side of the rafters. I figured that when the shakes and three layers of asphalt shingles came off, it would be a great time to roll in some fiberglass insulation, or if the current sheating is satisfactory, drill holes and blow in some fiberglass insulation. I believe that this would help fireproof the home since filling this open channel would eliminate any “chimney effect” in the event of a fire. Since I would not be using “faced” insulation, I suspect that the house would breathe adequately, also.
ANY SUGGESTIONS OR INPUT? SCOTTY/SIOUX CITY.
