Working on insulating my recently acquired 1965 home in East Tennessee.

Pictures tell the story best.

More details:
– Climate Zone 4a (Humid area in Cherokee Forest)
– 1300 sq ft
– No insulation other than old useless fiberglass batts. Even those were installed wrong with the paper up.
– Low slope roof: 2.8/12 (13.1°)
– Vent soffit cracks at top of eave where it contacts the roof. But notice the eave area is ~3-4 inches below the ceiling. (2 pictures for this, one is zoomed in)
– Notice the upright 2×6 making it impossible to physically get to the edges. Otherwise. I’d attempt to crawl in and install rafter vent and baffle.
– Previous water damage through old shingle roof
– Metal roof installed in 2020 on furring strips over the old shingles.
– Another roof leak after the metal roof was installed, but was determined to be due to missing washers on the roofing screws!!! 🤦
– Claimed there have been no leaks since then. I hope so.

Q: What would you do?

My thoughts:
– 1. I’m inclined to blow in cellulose or fiberglass, accepting that it will get wind washed and that it won’t be to depth at the edges. Anything is better than nothing.
– 2. I’m wary of spray foam due to the potential for moisture/condensation between the metal roof and the foam. Not to mention the cost.
– 3. And though I know cellulose is better and considerably cheaper, the concern over another roof leak has me considering fiberglass.
– 4. Local insulation companies are booked out ~4 weeks out, so I’d have to DIY before the winter storm. Or wait and burn more wood to stay warm (I have plenty of fallen trees).
