Double lay the first shingle course with the upper shingles overlapping the joints in the course beneath and both rows extending about 25 mm (1 in.) beyond the fascia boards at the eaves. This will prevent water from backing up underneath the shingles. Place shingles 6 mm (1⁄4 in.) apart to allow for swelling. Offset the joints between shingles in one course at least 40 mm (19⁄16 in.) from a joint in the
Use only two nails per shingle. The distance of the nails from the butt edge should be the shingle exposure plus 40 mm (19⁄16 in.), with an edge distance of about 20 mm (13⁄16 in.). For example, if the shingle exposure is to be 125 mm (5 in.), a nail should be 165 mm (69⁄16 in.) from the butt edge of the shingle being nailed. Use hot-dip galvanized or other corrosion-resistant shingle nails.
