Mishawaka ranches and split-levels commonly have first-generation decks from the 1980s–2000s entering replacement. Ledger flashing and footing depth are recurring inspection themes after ice seasons.
Attached decks need correct ledger flashing into the house weather barrier — missing flashing is a top moisture path into rim joists. Footings should reach below frost depth per local code.
Treat decks as outdoor living and inspection risk reduction. Document permits, flashing details, and material warranties for the next sale.
