How To Install Duraflash Vinyl Deck Flashing Under Door Lights

A+ and n+ pdf. Attaching a deck to your house creates the potential for rot, not only to the ledger board that you attach to the house to support the deck, but to the house framing. Builders avoid rot by installing flashing along the top edge of the ledger board, but even when this is done according to accepted practices, it creates a pocket for debris to collect, and this can rot the decking board closest to the house. Whether you have wood, vinyl or aluminum siding, you can avoid this by oversizing the ledger board and creating space for water to run off.
