Copper Flashings - A Manual - 1925 - Page 38
(§ 64 continued)
After the flashing is in place the reglet shall be filled and caulked, using molten lead on flat surfaces, and lead wool on vertical surfaces.
After caulking the reglet shall be made smooth by filling with elastic cement.
65. Reglets. (Masons' Specification.) Where indicated on the drawings or where directed by the architect cut reglets in the masonry as located by sheet-metal contractor for the insertion of flashings.
Reglets shall be not less than 1 inch wide and 1 inch deep. They shall be cut with true and straight edges, with sides and bottom roughened.
66. Scuppers. Flash all scuppers with copper, making same a part of the roof flashing. Scupper flashings shall cover the interior completely and shall extend through and project outside of the wall. Seams shall be locked, or lapped, and soldered. Scupper flashings shall be joined to roof flashings by soldered seams.
67. Scuppers. (Carpenters' or Masons' Specification.) All enclosed roof surfaces, including balconies, etc., shall be provided with scuppers. The bottom shall be not more than 2 inches above the finished roof surface at the lowest point.
68. Built-in Gutter-Linings. Where indicated on the drawings line all box or built-in gutters with copper. Gutter-linings shall fit loosely and shall have the back edge 3 inches higher than the front edge. Back edges of linings shall lock to copper roof covering and when used with slate, tile or shingles shall extend up the roof as far as possible without being punctured by the nailing of the roof covering, and shall be secured with cleats.
(-A.) Small sheets shall be laid with seams staggered. All seams shall be flat locked and soldered. Sheets shall be secured by cleats.
(-B.) Large sheets used to form gutter-linings shall be laid the long way of the gutter. The ends of the sheets shall be locked to cross strips about 4 inches wide by flat or double-locked seams fastened by cleats.
Great care shall be exercised to avoid any sharp bends or creases in the linings at the sides, and to this end sheets formed in the shop for linings shall not be bent more than 90 degrees. In so far as is possible all linings shall be formed on the job from flat sheets.
All gutter-linings over 24 inches wide shall have a longitudinal seam running the length of the gutter of flat or double-locked type, soldered and secured by cleats.
Linings shall be connected to flashings or to copper roofing by means of large loose-locked seams, folded flat and so placed as to avoid any possibility of leakage. In general the connection shall be made as close to the intersection of the roof slope and the inside of the gutter as is possible.
The back edge of all gutter-linings finishing against vertical walls shall be carried 4 inches above the outside edge of the cornice and shall be covered by cap flashings built into the wall.
(-1.) Gutter-linings in wood cornices shall have the front edges turned under the lower edge of an ⅛ by 1¼-inch brass strip screwed to the vertical face of the top member of the cornice. This strip shall he so placed as to form a proper drip.
(-2.) Gutter-linings set in stone cornices shall be placid over a wood sheathing forming the slope of the gutter. The outer edge shall be secured in a reglet. Where the wash slope slopes out, and where the width of the outer sheet of the lining exceeds 20 inches, a standing seam shall be formed as close as is possible to the reglet to prevent discoloration by the wash from the gutter and to provide for expansion.
(-3.) Gutter-linings in concrete or brick work shall be secured to batten or nailing strips set by other contractors according to directions by this contractor.
(-4.) Gutter-linings formed back of copper cornices shall have the front edge locked to the top edge of the cornice over ⅛ by 1¼-inch brass strip.
