I have a downspout that is falling apart. I'll try to explain the best I can. The downspouts I have are one piece, all metal. At the bends, it looks like the metal is cut, bent, then soldered. Anyway, one of the downspouts has pulled apart at the top bend,...the one that bends away from the house to join with the gutters. I'm not really sure if this requires soldering, brazing or some kind of patch. Can anyone help?
