Japantown gets its rainfall in a handful of concentrated winter storms, which means drainage that sat dry collecting debris has to move everything at once. Dust and grit settle on Japantown roofs through the dry months and wash into the drainage the soonest time it rains.

On most jobs, standing seam on a Japantown property hides its fixings, which removes the most common leak path on exposed metal. It is the same story on most Japantown streets.
