‘Test’ shingles, I’m guessing, have been going up since the new year at the Low/Martin House in Walkerville. I’m not too sure if it’s a direct replacement using cedar shingles. These look like just a test because they haven’t been stained/finished – unless the plan is to go with a lighter roof.
The roofing of this place is a big investment by its new-ish owner, who is putting much love and care into preserving this house! There’s a great discussion about the house on one of JohnTIZ’s flickr photos.
