    Default Shed roof attachment to brick veneer wall

    I understand the requirements (including the 2007 supplement) for deck's ledger to the structure, but what are the code requirements governing the attachment of shed roof over a patio or deck to a brick veneer wall?

    Engineering. The space behind the brick creates a big problem and an engineer would have to spec out an attachment method.

    Agreed.

    But in the case of a deck, R502.2.2.1 and R502.2.2.2 make it clear that engineering is required.

    Is there and equivalent for the situation where the "ridge board" of a shed roof meets a brick veneer wall?

    From the 2006 IRC. (underlining is mine)
    - R703.7.3 Lintels. Masonry veneer shall not support any vertical load other than the dead load of the veneer above. Veneer above openings shall be supported on lintels of noncombustible materials and the allowable span shall not exceed the value set forth in Table R703.7.3. The lintels shall have a length of bearing not less than 4 inches (102 mm).

    - R201.3 Terms defined in other codes.Where terms are not defined in this code such terms shall have meanings ascribed to them as in other code publications of the International Code Council.

    From the 2006 IBC.
    - VENEER. A facing attached to a wall for the purpose of providing ornamentation, protection or insulation, but not counted as adding strength to the wall.

    JP: Agreed. That makes all deck and roof ledgers non-compliant on brick and stone veneer. It also makes sellers and agents howl . . .
    poor babies.

    No, it means that ledgers at brick veneer have to "be designed in accordance with accepted engineering practice."

    I've seen it done, it don't know if it was these, but it was with something similar:

    Maine Building Materials; The Maine Deck Bracket Company; Minot, Maine

    the brackets had an ESR, and according to the builder getting approval was straightforward.

    No, it means the brackets are attached through the brick veneer to the structure, then the stairs, roof, etc., attached to the brackets, but NOT the brick veneer.

    Exactly, the ledger-bracket system was engineered to carry the load back to the rim joist.

    Michael: So then, your point is moot.

    My question was whether there is a code requirement equivalent to the quite specific ledger attachment requirements for decks.

    Based on the discussion above, it appears that there is not, and tat the only applicable code requirement is the more general requirement that a brick veneer wall not support a structural load.

    There is no specific ledger attachment of roofs and decks to brick veneer as the specific general requirement does not allow those loads to be attached to brick veneer.

    Thus, typically, the deck or roof is attached to the structure, the brick veneer run up to the underside of the roof or deck, then continued from shelf angle above the roof or deck and run up higher. Another way I've seen it done is to cantilever out main deck (balcony) supports from inside, then run the brick up behind the balcony floor and around the cantilevered beams. Either way, a compressible membrane sufficiently thick enough to allow for expansion of the brick and settlement of the structure is to be provided between the brick and the protrusion through the brick - otherwise the two will meet and one will fail, or at the very least the load is now unintentionally transfered to the brick veneer by virtue of full contact between the two.
    Other than that, like Aaron, I'm not quite following what you are asking.
