FAQ
What size roofing nail for shingles?
1-1/4 in is standard for three-tab and most architectural shingles; the nail must penetrate 3/4 in into the deck or through it, per the shingle instructions.
Why are roofing nails galvanized?
The roof is the wettest part of a building. A zinc coating keeps the nail from rusting and streaking the shingles.
