How to Attach a Ledger to Vinyl Siding

What You'll Need
Measuring tape
Table saw
Large carpenter's square
6-foot carpenter's level
Utility knife
2 x 8 lumber
1-1/2 inch wood screws
Masking tape
Power drill
1/2-inch spade bit
1/2 inch bolts

Attach your ledger board to your vinyl siding properly to have a sturdy moisture-proof deck support by following these steps.

Step 1 - Take Measurements

Measure the distance between floor joists, the height of the sill plate and add 1/2 inch for flashing to vent moisture from the ledger. Measure the length and width of your deck to attach the ledger correctly.

Step 2 - Cut Away the Vinyl Siding

Carefully cut away the siding with a utility knife braced along the edge of the carpenter's square to avoid slicing through the house wrap.

Step 3 - Add 2 x 8 Planks Between Joists

Measure and note from the basement and outside where the joists are, and insert 2 x 8 planks between them with 1-1/2 inch wood screws.

Step 4 - Insert the Flashing

Slip the flashing under the siding so it will cover the ledger board. Get 4 inches of the flashing under the bottom of the siding. Secure flashing with galvanized nails.

Step 5 - Attach Ledger Board

Drill 1/2 inch holes through the ledger board into the planks between joists. Fasten the ledger board with 1/2 inch bolts and washers.
