Copper Flashings - A Manual - 1925 - Page 37
58. Linings for Molded Gutters. Where indicated on the drawings install gutter-linings of soft (roofing temper) copper. They shall be shaped to fit the bottom of the gutter and shall slope toward the outlet. All joints shall be lapped and soldered.
59. Pole Gutters and Gutter-Strips. Where indicated on the drawings form gutters over wood poles or strips set by the carpenter contractor. Linings shall extend up the roof as far as is possible without puncture by nails, and shall be secured with cleats spaced 24 inches. Linings shall turn down over the pole and lock to a flashing strip, secured to the outer face of the pole by cleats and extending out over the roof covering at least 4 inches.
Outlets shall be provided with tubes soldered to the lining and of length sufficient to connect to the leaders.
60. "Shingle Flashings." All outlets of molded or pole gutters set on sloping roofs covered with shingles, slate, etc., shall be provided with a "shingle flashing," and a tube of length sufficient to connect to the leader.
This flashing shall consist of a sheet extending down the roof from the outside of the gutter at least one course of shingles and at least 6 inches up the roof under the gutter. It shall extend 6 inches on either side of the outlet. A sleeve shall be soldered to it and shall be inserted into the leader. The tube shall be set into this sleeve, which shall project down the leader beyond the end of the tube.
The flashing shall be constructed to prevent leakage under the gutter and down the outside of the tube through the hole in the roof sheathing.
61. Wire Strainers. (-A.) All gutter outlets shall be fitted with approved copper wire strainers of the basket-type set in loose.
(-B.) All gutter outlets shall be fitted with No. 14 gage copper wire strainers of the basket-type set in loose.
Vertical wires shall be spaced ½ inch, and shall be reinforced with horizontal wires 3 inches apart, extending around the basket, with each joint soldered.
62. Leaders, Conductors, or Downspouts. Leaders shall be installed where shown on the drawings, of the shapes and sizes indicated. They shall be held in position, clear of the wall, by
(-1.) Brass hooks, driven into the wall not more than 6 feet apart.
(-2.) Heavy brass or copper straps, ⅛ by 1½ inches, spaced not more than 6 feet apart, soldered to the leaders, and fastened (1) to wood work by brass screws; (2) to masonry by brass screws set in lead sleeves.
(-3.) Ornamental straps of (1) stock design; (2) the design shown, and made of (1) hard (cornice temper); (2) soft (roofing temper) copper.
Leaders shall be in 10-foot lengths, and shall be lapped, tinned inside and out, and soldered. A 1½-inch slip joint shall be provided every 20 feet of leader.
When leaders connect with underground drains they shall be fitted into drain-pipes and shall have the joint neatly cemented. All leaders not so connected shall have elbows at the bottom. Those discharging at ground level shall have heavy shoes with reinforced ends.
63. Leader Heads. Leader heads of (1) stock design; (2) the design shown, shall be placed where indicated on the drawings. Outlet tubes from gutters shall extend into them about 2 inches. The bottom of the leader head shall be soldered to the leader.
Large leader heads (12 inches wide or over) shall have a heavy copper-wire removable screening over the top.
64. Reglets. Where indicated on the drawings or where directed by the architect flashings shall finish in reglets in the masonry cut by others where located by this contractor.
The flashing shall be turned into the reglet the full depth and shall be turned back to form a hook.
