Flashing a deck the hard way

摘要

Remodeling contractor Andy Engel replies: It would have been so much easier if they'd done it right the first time! In any event, you'll need to remove a course or two of decking at the house, and a course or two of siding above the deck. If there's siding below the deck, you'll need to remove a course there as well. This will allow access to slip the new deck flashing under the house's weather-resistive barrier (WRB). You'll have to cut the WRB just above the ledger. Fold up the WRB to expose about 1 ft. of the sheathing above. Tape the WRB to the siding above to keep it out of the way.
