Hips are finished as shown at a, Fig. 55. The edges of the shingles should be cut to the proper angle and fitted into the groove b of the hip flashing.

Fig. 55.

Valley flashings, as at a, Fig. 56, should be made with a lock or fillet b at the edges of the gutter portion.

Fig. 56.

The edges of the shingles should be trimmed to the proper angle and turned over with a pair of hand tongs. The edges of the shingles should be made to clasp the edges of the valley fillet.

The chimneys and wall junctions are flashed as indicated in Fig. 57. The brick joints, as at a, are raked out, and a flashing of tin, of the shape shown at b, is formed with a groove into which the shingles are pushed. The flashing, having been inserted into the joint a, is secured to the wall with flashing hooks d, d, and the joint is carefully repointed with elastic cement.

Dormers and skylights may be flashed as shown in Fig. 58. The flashing a is turned up against the sheathing boards b and under the clapboards c, or other vertical side covering; the edges of the shingles are then carried up and fitted into the grooves.

The gable cap and flashing used with square-tailed shingles are indicated in Fig. 59. The molding a caps the start of all the rows of shingles and laps over the barge board b to which it is nailed.

70. Diamond-shaped shingles, as shown in the views (a), (d), and (c), Fig. 60, are laid in the same general manner as the Gothic, with the exception that the start may be made from either the right or left hand, as the case may require. The fillet a on the two upper flanges becomes a water-tight joint. The shingle is nailed through the lower edge of the flange b on each side. The central longitudinal rib c imparts rigidity and adds to the effect.

Fig. 61.

Hexagonal shingles, Fig. 61, are of the same construction as the diamond, save for the right-hand flange a, which is extended. The additional fillet necessitates the laying of these shingles from the left to the right.

71. The method of laying tile shingles, from the ridge to the eaves, is shown in Fig. 62. The ridge cap is the same as that used in the other methods. The lower flanges a of the shingles are made with a groove b into which the next course fits. The chief advantage of these shingles is that all scaffolding is removed as the roof is laid, and all difficulty in making a tight joint at the point of support for the scaffold is obviated.
