Just got back from re-inspecting a 1974 home i did last week. 2 story, 4 bed, 2 1/2 bath. The attic was insulated to 74’ standards. (74’ build) R-11 in the attic floor.
Some body added R-19 foil faced insulation between the rafters. 2 x6 rafters. There was a few areas where the insulation was loose and also around roof vents where i could see the deck. The vents basically rendered the rafter insulation useless, other than perhaps an R-2 for the reflective value of the foil.
The roof deck underside was darkened and saturated. (22% moisture content) when i inspected it last week. I HIGHLY recommended removal of the rafter fiberglass IMMEDIATELY. Looked like only 3/8 plywood. 5 YR. old re-roof with tear off. Architectural shingles. The west side was starting to delaminate in one small area, but it looked like it was drying out nicely and would be o.k. Wonder what people are thinking sometimes....
