    I remember others saying something about having seen it and tracing it down to what was used for the flashing, I think it was something with the applied flashing tape not withstanding the temperatures and the sealing membrane softening/liquefying and running down. Evidence that gravity wins.

    CVF,

    I am with Jerry on this. I seem to recall this occurring with some of the bitumen peel & stick window/door flashings. Might have been a defective material that started flowing when the weather warmed-up. I see it on occasion, and it's only at windows and doors.

    Sorry that I'm late to the party on this one, as I just saw it. It might not necessarily be heat related. It could also be a material compatibility issue. If the window flashing and and sealant/caulk aren't compatible (or even two different kinds of window flashing), then it could cause a chemical reaction and cause the black goo to melt and drip like that.
