Anyone got any details for deck joists landing on a shed roof? A client wants me to replace her existing second story deck, which has a ledger for 12 feet or so, which butts into the 1/2 gable of a shed roof over an addition. There are currently 6 joists which land on the 3/12 shed roof. These joists appear to be sitting on the sheathing and roofing over the rafters of the addition’s shed roof. The current situation is structurally unacceptable, and also has caused damage to the roofing. I know I won’t be allowed to re-create it. Any thoughts? Thanks. k

I looks to me that the roof actually Supports the deck some? Or is the roof notched around the deck joists?
Hey, wow, I got e-mail notification. Sweet.
Yes, you're right, those joists rest directly on the roofing. The deck was apparently done by the previous owner, who decided to land right there instead of changing the roof slope.
My client has of course gotten used to the deck (and addition) as it is, even though it never should have been.

Looking over the photos, to do a proper job would require you to either lower the pitch on the roof to allow a full height ledger and joists to be used straight across or step the deck up at that point to clear the existing roof. If there is a door entering onto the deck in that area, then you will be limited to building a flat, one level deck. But a two level deck could be done very creatively without having to touch the existing roof pitch.
Just make sure with either option, that the flashing is properly done where the deck ledger meets the wall and where the shed roof meets the wall.
That's pretty much what I'd
That's pretty much what I'd been thinking, but wanted to see if anyone else had a special counterflashing detail if I let the new joists into the shed roof, or something crazy like that.
The biggest problem with lowering the roof is that the bump-out now accommodates part of the kitchen, including can lights up above. Still doable, but a bit of work.
I warned the client that the whole back of her house may need to get opened up, as there are a number of messed up details that have undoubtedly been dumping water inside the structure.
I can't imagine how the contractor who did the kitchen re-model managed to not see any of the issues with the shell into which they inserted new counters, sinks, dishwasher, lighting, etc. But then, I've worked for a few companies like that- if you point that stuff out, you get labeled as "difficult".
There is a door above, although it's one of two, and could conceivably be done away with. A split level deck might work, although it would make tying the upper section to the house tricky, as it would be above the interior floor framing. Still, it is worth thinking about, especially as it will let the client know that I'm not hell-bent on ripping her semi-new kitchen open just for fun; the other options are problematic as well.
Thanks for the thoughts, keep 'em coming. Oh yeah, Happy New Year too.
