Directions
for Style A and Style C Metal Shingles
Any
carpenter with experience laying wood shingles will have no trouble with
metal shingles. They can be used on roofs one-quarter pitch or steeper.
Metal
shingles may be applied over old roofs. 6d nails should be used instead
of 3d, so that they will drive through the wood shingles into the
sheathing. The old roof acts as in insulator for heat and cold.
Otherwise start your roof with solid sheathing and waterproof paper.
Use a 2 x 4
toe hold for fastening to the roof, with galvanized strips 1½" to 2"
wide and about 18" long. Nail one end of the iron strips to the under
side of 2 x 4. Nail the other end into the sheathing above the last
course of shingles. After completion, snip strips off close to the
shingles.
Begin
laying shingles at the lower left corner of the roof. To make sure the
shingles run parallel to the eave, lock 3 or 4 shingles together and
place them on the roof without nailing. Remove all but the first,
carefully holding it in position. Nail the first shingle then proceed.
Project the first course 1" below the sheathing.
Start
alternate courses with a half shingle to break the joints. Use a chalk
line to lay shingles straight. Nail only on the nailing flange that will
be covered by the next shingle. When necessary to nail elsewhere, use a
galvanized nail with a rubber washer. Locate the nails where very little
water will run over them.
When
flashing against a side wall, bend the shingles so they project up the
wall 3", and counter flash within 1" of roof. This applies to dormers,
chimneys and skylights.
Where
applicable, lay a valley from eave to comb, nailing only the outer
flange. Cut the shingles to the same angle as the valley, allowing them
to project ¾" over the pocket, and turn them under to form a hook.
For ridge
and hip areas, we recommend our individual tiles or our continuous
finishes. A variety of finials will complete your job. Any questions
