Sure they do. Nice, solid copper ones - solid copper screens, that is, floor
to ceiling. Even a modest windy rain sprays water 4 feet in, then it ponds,
the wind blows the ponds in even farther. (Father-in-law sort of forgot
about slope, apparently. That darned Gropius guy!) He also put the
perimeter weepholes (horizontal) in about 1/2' above the surface. But
they're brass tubed, and very nicely detailed.
Sign me, I don't care what happens in the winter.
