| Before placing wood shingles, cover the roof with plain paper, if paper is required. Do not use asphalt impregnated paper because it prevents moisture under wood shingle roofs from escaping. Extend the shingles beyond the fascia by 1 inch (25 mm), to allow water to drain off the roof slope. Double or triple the first course of shingles at the eaves. Shingles are placed with their butts downslope, 1/4 inch (6 mm) apart, and nailed with 2 nails, 3/4 inch (20 mm) from the shingle's edge. Shingle joints on the upper layer are not to be any closer to the lower layer shingle joints than 1 1/2 inches (40 mm). A straight edge, chalk line or shingling hatchet can be used to keep shingles in a straight line at their correct location. |
