Should there be a gutter formed at the eave, let the shingle rest on it as you would in using the ordinary wood shingle. (Remember every other course commences with a half shingle, as shown in Cuts A and B.) The same rules that govern the laying of slate or the common wood shingle along valleys, or about chimneys and dormer windows, are applicable to ours, except the tin shingles are bent up against the sides of chimneys, which cannot be done with wood or slate. When our shingles turn up against the sides of chimneys or brick walls, insert flashing by sawing out the mortar joint above the line of tin work; where the upper edge of our shingles butts against the brick wall, as they do on the lower side of chimneys, cut them off on the line where the chimney comes to the roof, and use a strip of tin bent in this manner. (See Cut F.) The upper end at A is to fit in mortar joint. The lower edge, B, is nailed to the sheathing before the shingles are put on. The upper ends of shingles are then to be pressed up under the fold, C. Great care should be used in finishing about chimneys and dormers, the details of which cannot well be explained to suit each case; but a workman of ordinary skill can suggest the proper manner in which the work should be done to secure thoroughly tight work.
It is much easier to secure this result with the use of our shingles than it is with either wood or slate.
Where the upper end of shingle butts against the side of a frame house, use the same means as on the lower side of chimneys, only let there be no bend at the point A, as shown in Cut F; but let it extend an inch or so up under the weather boarding. Where the weather boarding is vertical there is no way of making tight work but to put the tin work, as before described, back of the vertical weather board.
In laying the valley, cut the tin so it extends to about one-half inch over the lock, and bend it under, as shown in Cut D. We furnish to each customer a small pair of hand-tongs, which is handy to turn this edge over and pinch it together after the shingle is laid.
Cut D.
The Cut D represents the shingles laid to and from the valley. In starting from the valley it is best to hold several shingles together, or tack them at the top, then with a straight-edge mark and cut where they overlap the valley; and with the hand-tongs edge and lock them to the valley, as shown in cut D.
Use the Hip Coping by nailing the edges to the roof boards, and press the shingle up under the folds on each side after they are cut to suit the angle of the hip. (See Cut E.)
