As mentioned in an earlier post on this blog, this past winter ATC undertook to replace the siding and doors on the smaller "sheep" barn. This project has meandered along and been mostly quiet this summer, but is 98% complete. Lumber ran short in early summer and I decided that the project could sit until later in the fall when the last 3 doors would be built and installed in time for winter.
The next barn project, which has really been going on for a year and a half now if you count the pre-planning and fundraising stages, was to renovate the roof of the main barn. This was a large project that required a roofing contractor, engineer, building permits, etc. The impetus for this project was that the existing roof (asphalt) was failing and ATC was concerned that the irreplaceable chestnut timber-frame structure would be damaged. I frequently observed shingles blow off of the barn in high winds, particularly in winter. The structure gets full sun and wind exposure and takes a bit more of a beating from the elements being the tallest building on the property. ATC has spent the last two years convening a group of staff, board members, and volunteers each quarter to discuss the future of the property and how to make it sustainable. Out of that conversation we have identified the need to renovate the barn, in multiple phases, to serve as a more "public" space: a spot for events, meetings, and education. The first phase we settled on is to insulate and replace the existing roof so that we would be able to eventually convert the structure to 4-season use. This is a multi-year project that will require a significant capital investment by ATC.
Interestingly, when Henderson Roofing began stripping shingles off they found that there were 6 layers: 1 layer of cedar shingle, 5 layers of asphalt. That is 28,000 lbs on the roof!! So the structure is undoubtedly breathing easier now. ATC is in the process of applying to Historic New England to hold the Historic Preservation Restriction on all of the buildings here, so we asked them to render an opinion on which material was most suitable for the replacement given the age and history of the structure. The choices were standing-seam metal, cedar, or asphalt shingles. Standing-seam was our first choice for its longevity while asphalt was our last for the same reason. We never really considered cedar until it was discovered to be the original covering. As a result we decided that restoring the roof to its original covering made the most sense. Henderson Roofing replaced the degraded wood gutters with copper and also insulated the roof with 3 inch foam board. The whole job start to finish took about 6 weeks.
