[Greenbuilding] Flashing On To Concrete Deck Roof

[Eli Talking]

I have a flashing challenge I hope this list can help me with.  I am making 
a link to an addition.  It meets up to existing building that features a 
concrete slab roof.  I am framing  gable end roof over the concrete slab to 
the interior side of the existing exterior wall.  The framed soffit of the 
gable roof is to set about 10" above the deck.  I need an adhered flashing 
that can protect this wall from moisture.  I will not be able to overlap 
flashing as I would normally want to.  I hope someone can advise me as to a 
good product for this purpose. Thanks in advance for your consideration.
