- Calculate the height and horizontal position where the edge of the deck will be attached to the house. Place a 2-by-6 board of the correct length in position and mark its location on the siding. Use a level sitting on the top edge of the board to determine the correct pitch. This will be your ledger board.
- Cut along the outline of the ledger on the vinyl with a utility knife and remove the siding from the outlined area. Remove any insulation or other flexible material inside the cutout.
- Use an electronic stud locator to find and mark all of the framing studs inside the cutout. Place the finder flat against the wall and depress the buttons on either side. Move the locator along the wall and make a mark every time it lights up and the locator beeps. Mark these stud positions lightly in pencil on the siding directly above where the ledger will be attached for easy reference.
- Bore 1/4-inch holes through the ledger corresponding with the studs on the wall with a wood boring bit and a cordless drill.
- Hold the ledger board in position, making sure to line up the holes with marked stud locations. Drive one 1/4-by-3 inch lag screw into each stud through the pilot holes you drilled previously.
- Cut a piece of L flashing long enough to cover the top of the ledger board. Apply a bead of flashing caulk along the back of one face of the L flashing. Slip it up under the siding directly above the ledger with the caulking against the wall. This will prevent water seeping behind the siding below the ledger.
- Attach a joist hanger to the face of the ledger board every 16 inches using 5/8-inch treated deck screws. Use them to support the deck joists. This will create a tight bond between the vinyl sided wall and your deck.
How to Attach a Deck to Vinyl Siding
Vinyl siding is a common material used in both new construction and remodeling. It can be applied directly over wood, plywood siding or chipboard sheathing. Its flexibility and lightweight construction make it long-lasting and easy to work with, but less than ideal as a foundation for secure attachments. The use of a rim joist, or ledger board, attached to the substrate and framing of the wall itself is the best solution. Always use treated lumber and screws for outside construction, particularly projects that attach to the house.
