How To Attach A Ledger Board Stucco House For Patio Cover

How to Attach a Ledger Board to a Stucco House for a Patio Cover

Creating a sturdy and weather-resistant connection between your stucco house and your new patio cover requires proper installation of a ledger board. This guide provides a step-by-step explanation of the essential aspects you need to know for a successful and secure installation.

Materials Required:

Ledger board (typically pressure-treated lumber)
Lag bolts (with washers)
Concrete screws (with washers)
Drill with appropriate drill bits
Impact driver
Level
Masonry bit (if drilling into stucco)
Caulk (for sealing gaps)

Step 1: Determine Ledger Board Placement

Mark the desired height and location of the ledger board on the house wall. Ensure it aligns with the supports of your patio cover and is positioned at the appropriate height for drainage.

Step 2: Install Flashing

Install flashing over the top of the ledger board to prevent water from entering behind it. Flashing should extend at least 6 inches beyond the edges of the ledger board and should be secured with concrete screws.

Step 3: Create Pilot Holes (for Stucco)

If installing into stucco, use a masonry bit to create pilot holes for the lag bolts. These holes should be slightly smaller in diameter than the lag bolts and should be deep enough to penetrate the stucco and into the underlying wood framing.

Step 4: Install Ledger Board (for Stucco)

Position the ledger board against the house wall and insert the lag bolts through the pilot holes. Use an impact driver to tighten the bolts securely into the wood framing. Ensure the ledger board is level and flush with the wall.

Step 5: Create Pilot Holes (for Concrete)

If installing into concrete, mark the locations of the concrete screws on the ledger board. Use a drill with an appropriate concrete bit to create pilot holes for the screws.

Step 6: Install Ledger Board (for Concrete)

Position the ledger board against the house wall and insert the concrete screws into the pilot holes. Tighten the screws securely using an impact driver. Ensure the ledger board is level and flush with the wall.

Step 7: Seal Gaps

Caulk any gaps between the ledger board and the house wall to prevent water infiltration. Use a caulk that is compatible with both stucco and wood.

Additional Tips:

Use corrosion-resistant lag bolts and concrete screws for durability.
Space the lag bolts or concrete screws no more than 24 inches apart.
Consider using a ledger board connector for added strength at the connection point.
Consult with a licensed contractor if you have any concerns or require professional assistance.

By following these steps and adhering to the additional tips, you can ensure a secure and long-lasting attachment of your ledger board to your stucco house for your patio cover.
