Finish at HipsHips are made, in this type of roofing by cutting, the strips to the proper angle, and allowing 2 inches in the length. A single-lock joint is then formed as for a ridge. The seams in the roof are also neatly flattened as shown in shown in Fig. 21.

Finish at Valleys Valleys are formed of full-width strips of the roofing, laid from bottom
to top of the valley, care being observed to have the cross-seams a, Fig.
38, so laid that the water will run over the seam instead
of against it. The edges "b" of the valley strip are
turned over ½ inch to form a single-lock seam, and are fastened
with cleats "c" at 12- or 14-inch intervals. A corresponding
lock "d" is formed on the lower edge of the roofing
strip e. This strip is fitted against the strip "f",
already in place, and locked into the valley strip. The seam at "b"
is flattened down, making a tight joint. |
