Attic roofing nails are specialized fasteners designed for securing shingles and roofing materials in your attic or underlayment. In this concise guide, we’ll explore the technical details of attic roofing nails, their uses, and key specifications.

Attic Roofing Nails: What Are They?

Attic roofing nails, often referred to as "underlayment nails" or "felt nails," serve a vital role in the roofing process. These nails are typically used to secure the underlayment, which is a water-resistant layer installed beneath the roofing material. The underlayment acts as a barrier against moisture and provides an additional layer of protection for your roof.

Key Technical Details

Material:

Attic roofing nails are commonly made from galvanized steel, stainless steel, or aluminum. These materials offer excellent corrosion resistance, ensuring the long-term durability of the nail, even in challenging weather conditions.

Shank Type:

The shank of attic roofing nails can be smooth or ring-shanked. Ring-shanked nails provide enhanced holding power due to their twisted, textured surface, reducing the risk of nail pull-out.

Length:

The length of attic roofing nails typically ranges from 1 to 2 inches. The appropriate length depends on the thickness of the underlayment and roofing material being used. For thicker materials, longer nails may be required.

Shank Diameter:

The diameter of attic roofing nails varies, with common options being 11 or 12 gauge. The choice of gauge depends on the specific requirements of your roofing project.

Uses of Attic Roofing Nails

1. Underlayment Installation: Attic roofing nails are primarily used to secure the underlayment to the roof decking. This step is crucial to ensure a waterproof barrier beneath the roofing material.

2. Temporary Fastening: These nails can also be used temporarily to hold roofing material in place before permanent fasteners like roofing nails or staples are applied.

Installation Tips

When working with attic roofing nails, it’s essential to follow best practices:

1. Nail Spacing: Nails should be spaced according to the manufacturer’s recommendations, typically around 6 to 12 inches apart.

2. Proper Angle: Attic roofing nails should be driven in at a slight angle to ensure a secure hold. Ensure the nail heads are flush with the underlayment.

3. Use the Right Tools: A pneumatic nail gun or a hammer is commonly used to drive attic roofing nails. A nail gun can expedite the process while ensuring consistent nail depth.

4. Weather Considerations: Attic roofing nails should be chosen based on the local climate. In areas with high humidity or exposure to saltwater, stainless steel nails are recommended for their superior corrosion resistance.

Conclusion

Attic roofing nails play a crucial role in ensuring the longevity and weather resistance of your roof. By understanding the technical specifications, proper use, and installation tips for these nails, you can contribute to the overall durability and performance of your roofing system. Whether you’re a professional roofer or a homeowner embarking on a roofing project, having the right attic roofing nails and using them correctly is key to a successful roofing endeavor.
