What flashing detail BEST protects the house at a deck ledger connection?
a.No flashing, just caulk the top
b.Corrosion-resistant flashing that directs water out over the ledger and integrates with the wall's water-resistive barrier
c.A strip of untreated cardboard
d.Painting the ledger black

Proper ledger flashing is a corrosion-resistant metal or approved flashing lapped so water sheds out and away over the top of the ledger and integrates with the WRB, preventing rot behind the ledger. Caulk alone, cardboard, or paint do not create a durable, integrated drainage detail.
