Waterproof Ledger Protection

Self-adhesive ledger tape creates a continuous waterproof barrier between the deck ledger board and house rim joist, blocking water infiltration that causes rot, mold, and structural failure behind the wall.

Butyl Rubber Adhesion

Butyl rubber formulation bonds permanently to wood, concrete, and steel framing surfaces, maintaining a watertight seal through Missouri's freeze-thaw cycles and seasonal temperature swings.

Z-Flashing Integration

Metal Z-flashing directs water away from ledger connections and rim joist penetrations, channeling moisture off the structure before it reaches framing members or house sheathing below.

Post Base and Beam Protection

Flashing tape wraps post bases, beam ends, and joist hangers to seal hardware penetrations, preventing corrosion at metal-to-wood contact points that commonly fail in high-moisture environments.

Maintenance

Clean the Ledger Surface Before Application

Remove all dust, debris, and moisture from the ledger board and rim joist surface before applying tape, contaminated surfaces reduce adhesion and create gaps where water can penetrate.

Overlap Tape Seams by a minimum of 2 Inches

Always overlap ledger tape seams by at least 2 inches, working from bottom to top like shingles. This ensures water sheds away from the structure rather than behind the tape layer.

Install Z-Flashing Above the Ledger Board

Tuck metal Z-flashing behind the house siding, and over the top edge of the ledger board. This diverts roof and wall runoff away from the ledger connection before it reaches the tape layer.

Seal All Fastener Penetrations

Apply a patch of ledger tape over every lag bolt and screw penetration point after fastener installation, unsealed penetrations are the most common entry point for water behind Missouri deck ledgers.

Wrap Post Bases and Beam Ends Completely

Use flashing tape to fully wrap post base hardware and exposed beam ends. Direct wood-to-metal and end-grain contact points absorb moisture fastest and require complete coverage for lasting protection.
