Sheathing And Covering Roofs4

Roof hips and ridges are shingled with edge grained shingles of the same width. Shingle widths are at least 1 inch (25 mm) wider than the exposure. A chalk line is snapped on each side of the hip centreline at a distance equal to the exposure. The top edge of the shingles are then bevelled to the plane of the adjacent roof surface. The first shingle is placed on the chalk line and the next is placed on the other chalk line. The next pair of shingles is placed in reverse order and so on. Make sure the nails in the shingle below are covered by the shingle placed above it.
