The Slate Dome

We visited quarries in the same area of Vermont that the original slate had come from 80 years earlier. If you look very closely today, with binoculars, you may be able to see the line of the replacement shingles, although we count on them weathering to match the original shingles still in place.

The “flat” sections of the roof were finished with an unusual Monel flat seam roof. Monel is a naturally occurring binary alloy of nickel and copper, which is no longer widely used now that the deposit is depleted. Since we couldn’t replace in kind, we designed flat and standing seam copper roofs, integrating a layer of rigid insulation for the previously uninsulated attic.
