Flashing deck ledger board vinyl siding.

A simple metal or plastic cap flashing is probably adequate to flash a deck ledger in a dry climate while the 3 layer system described in this video is suitable for high rainfall and damp climates. You should allow the flashing to move from side to side in the slotted hole provided. When you install the floor joists you ll need to make some small cuts in the flashing to allow the top of the joist to line up with the top of the ledger board. Make the outline large enough to include space for the deck boards on top the ledger and any trim boards on the sides.

Step 2 cut away the vinyl siding. Properly installing a ledger board for your deck is one of the most important structural components of building a safe and strong deck. The irc doesn t provide prescriptive measures for flashing other than the minimum thickness for metal flashing 0 019 in. Snap a chalk line cut out the siding and tack up the ledger board.

Next you ll want to install a piece of metal drip cap flashing above the ledger board. Measure the length and width of your deck to attach the ledger correctly. Then slip flashing behind the siding covering the top edge of the ledger. Window and door cap 1 25 in x 120 in x 1 56 in aluminum z flashing.

The nails should not be nailed tight to the flashing. Cut a length of metal z flashing with tin snips to cover the entire length of the ledger board allowing an extra 1 2 inch to overhang each end. Start by making an outline on the siding where you want to position the ledger board. Make sure the house wrap is long enough to cover over the top of the drip cap.

Slip the top edge of the flashing under the siding.
