One of American Wood Council’s most commonly downloaded publications is the Prescriptive Residential Wood Deck Construction Guide (DCA6). This presentation provides a deck experts perspective on deck construction which is not included in DCA6. One of the leading contributors to exterior deck collapses is decay of the supporting structure - namely the rim joist of the house - due to poorly detailed or damaged deck ledger flashing. This program will examine a step-by-step flashing process that protects the wall behind the ledger and flashes over the top to block and redirect water onto the face of the ledger and cladding at three critical areas. A flashing approach to seal cantilevering deck / balcony joists where it penetrates through an exterior wall and WRB will also be examined.

Also discussed are solutions to address critical deck stair support, connections, construction and safety details: specific attention to the top of a stairway to the deck; the required footing at the base of a stairway; stairway landings; riser openings and stabilizing the bottom stairway guard post.

Learning Objectives:

1. Describe a redundant ledger flashing system that reduces the chance water leakage into the wall assembly of the dwelling
2. Identify IRC provisions for deck ledger flashing and label the layers of a ledger flashing system
3. Differentiate between decks that require stairway footings that extend below frost line from decks that do not require frost-depth footings
4. Describe common issues with deck stairway to deck frame attachments

Equivalencies: 1.5 Hour of Instruction = 0.15 Continuing Education Units (CEU) = 1.5 Professional Development Hours (PDH) = 1.5 Learning Units (LU)
