Installing a Ledger Board Around a House Corner for Your Composite Deck
Technical note: Installation details vary by municipality, product line, board profile, fastening system, loads, and site conditions. Use this article as general guidance only; confirm the final design with your local building department, the manufacturer's current installation guide, and a qualified contractor or engineer when structural loads are involved.
To ensure the strength and durability of your composite deck, proper ledger board installation is essential, especially when going around a corner of your home. At Magasin de Patio, we guide you step-by-step through this key process for your outdoor living space.
1. Preparation and Removal of Exterior Siding
When your ledger board needs to extend around a corner, it is necessary to:
- Remove siding and corner post: To ensure a solid attachment, remove the siding and corner post to expose the house structure.
- Level both ledger board sections: The two segments meeting at the corner must be perfectly aligned and level to avoid any misalignment.
2. Professional Fastening and Waterproofing
To prevent infiltrations and ensure long-term hold, follow these recommendations:
- Overlap assembly without miter cut: Opt for a direct overlap rather than a miter cut to strengthen the joint.
- Use the right hardware: Firmly nail or bolt the ledger board with specific fasteners for composite wood like those from Fiberon, TimberTech, Trex, or TruNorth.
- Install appropriate flashing: Install continuous flashing and a water-resistive detail above and behind the ledger as required; do not rely on caulking alone.
- Silicone caulking: Use compatible sealant only as part of a complete flashing detail, especially at the vertical corner joint.
3. Do Not Treat the Ledger as a Freestanding Beam Without Design
A ledger board should not be extended past the house and treated as a load-bearing beam unless that condition is specifically detailed in the approved framing plan. Where the deck continues beyond the wall, use a properly sized beam, post, and footing/pile layout, or have the condition reviewed by an engineer.
- Load path: deck loads must transfer through beams, posts, and foundations sized for the project.
- House attachment: the building structure should not be used to eliminate required frost-protected supports unless the design allows it.
- Fasteners: use structural fasteners specified for ledger connections and compatible with treated lumber.
