Thomas Jefferson’s skyline is coming back to the University of Virginia’s Lawn.
Jefferson designed his Academical Village with flat roofs over the student rooms – an angled, serrated roof topped with a flat deck. Jefferson wanted the water to run through the deck boards and onto the tin-lined valleys of the serrated wood roofs before running off onto the ground.
But these roofs leaked, and in the 1830s, carpenters installed pitched slate roofs over the Jeffersonian roofs, stopping the leaks and preserving the original roofs by encapsulating them.
“These are the Jefferson serrated roofs – the ‘ridge and furrow,’ as it was called in the day,” project manager Amy Moses said. “There are still sections remaining that didn’t get removed when they installed the 1830s roof, nor when they redid the 1830s roof in the 1990s.”

Now, using modern materials, University workers are restoring the original appearance. Workers started on the west side of the Lawn in 2010, replacing the roof sections every other year, and are now nearing completion on the east side.
“We are removing the gable roofs and going back to a flat roof,” Moses said. “It is slightly higher than the Jefferson era/designed roofs, because we are preserving the remaining portions of the Jefferson era roof underneath the new, but it’s mostly in line with where Jefferson would have had his flat roof.”
While Jeffersonian in appearance, the new roofs incorporate modern technology: multiple layers of rubber membrane, with “sleepers,” or structural supports that hold the deck over the roof surface.
The workers are not just replacing the gabled roofs, which were last replaced in 1994; they are also replacing the Chinese rails, again returning to the original Jeffersonian design. The railings, which have been replaced many times over the years, have become misaligned and their patterns altered.
