When installing shingles or a metal roof, the question often asked is what length roofing nails should I use? Generally, nails of 1.75″ in shank length should penetrate the material they are fastened to. The length will depend on the number of layers, thickness of shingles, underlayment, flashings, and other variables. Roofing nails should be corrosion-resistant. Copper and stainless steel nails are good choices for basic roofing. If you have wood shingles, you’ll need longer nails. best roofing company near me
When installing shingles, the nails should penetrate all layers of material, including the roof deck. The nails should extend at least one-eighth of an inch through plywood or wood planks unless the materials are thinner. In these cases, a nail that is 1/8 inch long is appropriate. If the shingles are thicker, use a nail of at least one-half inch long. You should always measure the shingles to be installed and then determine the length of the nails used.
If you are installing new shingles or decking over an old layer, you should use a one-half-inch nail. If the decking is less than 3/4-inch thick, use a nail with an inch-long shank. If you are installing new shingles or a thin layer of old shingles, you can use a nail with a one-half-inch shank. However, remember that a 1.5-inch nail is too short if the material is too thick or if the nail is too long.
The guidelines for the length and diameter of roofing nails are more vague than the ones for their diameter. This is because nails have different lengths depending on the shank type. For example, wood shingles need a longer shank than architectural shingles. Fiberglass shingles require shorter nails, while asphalt-style shingles do not require nails with longer shanks. If you’re unsure of what length to use, you should contact your local building department and ask for specific nailing applications.

And don’t forget to consider your exposure and coverage to wind, since the more exposure, the fewer nails you’ll need.
If you’re using 1” nails, keep in mind that they are more likely to pop out of the sheathing during installation and may need to be removed. While this may seem like a trivial thing to consider, it’s crucial to avoid overdriving nails as these can damage shingles. If you don’t know the correct length of roofing nails, you could end up with a damaged roof and need to replace the entire roofing.
