1 Make sure your ledger board (main support board attached to house) is properly secured and flashed. There should be a minimum of 8” of flashing out from ledger board (FIG.1-A) . If flashing does not extend past the gap between the first two deck boards, install gutter along ledger board after DrySnap system is installed.
