Designed for flashing deck ledgers, 11-inch-wide Trex Seal Ledger Tape combines butyl tape with a reinforcing aluminum liner. With the wider size, the tape doesn’t need to be lapped, so it can create a seamless seal over the gap between the ledger and the house. A split release liner allows installers to attach half the flashing to the house wall, and then fold and attach the other half to the ledger. We found 50-foot rolls online for between $235 and $275. trex.com
