About
Joist tape and deck flashing protect deck framing — joists, beams, ledger boards, and stair stringers — from moisture intrusion, the leading cause of wood rot and structural decay. Applied before decking installation, these self-adhesive tapes seal around fasteners and block water penetration, extending the life of your deck for a fraction of the total build cost. Shop joist tape and flashing from Trex, FrogTape, G-Tape, CAMO, Deckorators, FastenMaster, and more in widths from 1-5/8" to 12".
