This past autumn, workers from Peter Post Restorations lead by Peter himself added the shingles to the roof of the Washington house at Ferry Farm. The handmade riven shingles were sawn from a tree trunk, smoothed on one side, and decoratively scalloped. Because they were handmade, each shingle was a different width. The roofers laid the shingles in a pattern to compensate for the different sizes and then nailed them into place.
The most challenging aspect of roofing the Washington house was shingling where the roof met the dormers. In the 18th century, roofers curved the wood from the roof to the dormers creating “swept valleys” that are gorgeous examples of historic craftsmanship.
