Settled fiberglass batts leaving bare spots at the eaves
Why it happens here
Builder-grade batts compress and shift over time, especially in attics that see big temperature swings. In South Pleasant Grove, the outer edges of the attic floor are usually the first to go bare, which is exactly where ice dams start.
Our approach
We air-seal the attic floor first, then blow cellulose to a consistent R-49 depth. The blown material fills around joists and wiring that batts miss. We mark the depth so you can verify it.
