How do you attach shingles?
Shingles are easy to nail in place with roof nails. They have a flat wide head, which makes them easy to nail. You drive a nail above each tab incision and at the edge of the shingle. A 3-tab shingle calls for 4 nails per shingle; a 5-tab shingle requires 6 nails. You always nail through 2 shingles.
