As mentioned in the April 17th post about historic nails, the wood sheathing for the two small roofs on the tower is historic fabric. The boards measure somewhere between 17-20 inches in width. Boards of that size are most likely from old growth forests and in our case that means the boards likely date to 1747-8. The majority of these boards are being put back into place in preparation for the new copper roofs being installed this week. The only boards not going back are ones that are in too poor shape to be reused.
