Does anyone have any suggestions on clearing blocked downpipes?

Position garden hose at top of downpipe. Squirt, full blast, down the pipe.
Usually the hydrostatic pressure, or just the nozzle pressure, will dislodge
the contents, depending on how long they have been blocked. If a hose won't
do it, try an auger or snake, from the top.
