Roof framing attached to masonry veneer??

[JCraver]

New construction, 2009 IRC

I found the section in the code that says you can't attach a deck ledger board to a masonry/brick veneer. My situation is a covered porch hip roof, approx. 12' x 5' - framer wants to attach roof framing to a properly-installed full height (2 story) brick veneer. I would have sworn that wasn't allowed, but not finding it.

Any ideas? Thanks.

For bearing or uplift?

Look at figure R703.7...maybe....Scratch that, now I see what you are asking....Standby..My gut says that a veneer is nonbearing by definition, but I haven't found a definition yet...

Prescriptive codes give requirements on how something must be accomplished and exceptions to those requirements. If something is not covered in the codes it is not permitted. I would agree that generally attaching roof framing to brick veneer is a poor idea, not just for the load bearing conditions, but also due to the moisture load that the wood will experience from the brick.

Masonry veneer walls consist of a single non-structural external layer of masonry work, typically brick, backed by an air space. The innermost element is usually structural wall, and may consist of wood or metal frame within the Cavity wall (where inner and outer layers are both structural) while others are distinct to masonry veneer walls:

2009 703.7.3, 2015 703.8.3 might be what you are looking for. Both indicate that masonry veneer can not support any load other than the load of the veneer above.

Thanks Sifu...I knew that was there somewhere.....

Yes, Thank You. I knew it was there too, just couldn't find it.

Thanks again, all.

I'd think flashing would be very difficult as well.
