Most of all, though, you are beset by what in other contexts is the veritable stuff of life: water. It always wants in.
After we’re gone, nature’s revenge for our smug, mechanized superiority arrives waterborne. It starts with wood-frame construction, the most widely used residential building technique in the developed world. It begins on the roof, probably asphalt or slate shingle, warranted to last two or three decades—but that warranty doesn’t count around the chimney, where the first leak occurs. As the flashing separates under rain’s relentless insistence, water sneaks beneath the shingles. It flows across four-by-eight-foot sheets of sheathing made either of plywood or, if newer, of woodchip board composed of three- to four-inch flakes of timber, bonded together by a resin.
Newer isn’t necessarily better. Wernher Von Braun, the German scientist who developed the U.S. space program, used to tell a story about Colonel John Glenn, the first American to orbit the Earth. “Seconds before lift-off, with Glenn strapped into that rocket we built for him and man’s best efforts all focused on that moment, you know what he said to himself? ‘Oh, my God! I’m sitting on a pile of low bids!’”
In your new house, you’ve been sitting under one. On the one hand, that’s all right: by building things so cheaply and lightly, we use fewer of the world’s resources. On the other hand, the massive trees that yielded the great wooden posts and beams that still support medieval European, Japanese, and early American walls are now too precious and rare, and we’re left to make do with gluing together smaller boards and scraps.
