South Bend's older lots often have aging wood decks with ledger flashing failures — a common inspection red flag after Michiana winters. Snow load, freeze–thaw, and wet springs punish skimpy footings and missing flashing.
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.
