Selecting the appropriate nails for roofing paper installation is a critical aspect of ensuring the longevity and effectiveness of your roofing project. In this guide, we will cover the key technical details and considerations for choosing the right nails for roofing paper, making the process clear and straightforward for both professionals and non-technical enthusiasts.

Understanding Roofing Paper

Before we delve into the specifics of nails, it’s essential to understand the role of roofing paper in the construction and maintenance of roofs. Roofing paper, also known as roofing felt or underlayment, serves as a protective barrier between the roof deck and the final roofing material, such as shingles. Its primary functions include:

1. Moisture Barrier: Roofing paper acts as a moisture barrier, preventing water and moisture from infiltrating the roof structure. This is crucial in preventing leaks and water damage.

2. Protection from Weather: It provides an extra layer of protection against wind, hail, and other environmental factors that can affect the longevity of the roof.

3. Deck Protection: Roofing paper also shields the roof deck from resin and sap in wooden shingles, which can cause rot.

Types of Roofing Nails

Roofing nails come in various types, each suited to different roofing materials and applications. The most common types are:

1. Coil Roofing Nails:

• Material: Coil roofing nails are typically made of galvanized steel, which is corrosion-resistant.
• Shank: They often have a smooth shank for easy penetration.
• Head: These nails have a broad, flat head for secure fastening.
• Application: Coil roofing nails are suitable for asphalt and fiberglass shingles.

2. Cap Nails:

• Material: Cap nails are also made of galvanized steel for corrosion resistance.
• Shank: They have a smooth shank.
• Head: Cap nails have a larger head with a plastic or metal cap, which helps to secure roofing paper in place.
• Application: They are specifically designed for fastening roofing paper or underlayment.

3. Roofing Staples:

• Material: Roofing staples are often made of galvanized steel.
• Shank: They have a narrower, flat shank.
• Head: Staples have a smaller, crown-shaped head.
• Application: Roofing staples are primarily used for attaching roofing paper and housewrap.

Key Considerations for Nails

When selecting the right nails for roofing paper, consider the following factors:

1. Material Compatibility:

Ensure the nails you choose are compatible with the roofing material you intend to install. For most standard roofing papers and underlayments, coil roofing nails or cap nails are suitable.

2. Corrosion Resistance:

Galvanized steel nails are the preferred choice for roofing projects due to their resistance to rust and corrosion. This ensures the longevity of the fasteners and the integrity of the roof.

3. Shank Type:

For roofing paper, smooth shank nails are generally adequate. However, if you’re working in an area with strong winds or require extra security, consider ring shank nails for superior holding power.

4. Length:

The length of the nails should be sufficient to penetrate the roofing paper and secure it to the roof deck beneath. A typical length for roofing nails ranges from 1 to 1.25 inches.

Installation Tips

When using nails for roofing paper, adhere to the following best practices:

1. Spacing: Nails should be spaced approximately 6 inches along the edges and 12 inches in the field. This ensures adequate support without overusing nails.

2. Securely Fasten: Ensure that the nails are driven flush with the roofing paper. This prevents tearing and provides a smooth, even surface for the final roofing material.

3. Safety: Always use appropriate safety gear when working with nails and roofing materials, including eye protection and gloves.

Conclusion

Selecting the right nails for roofing paper is a critical step in ensuring the durability and effectiveness of your roofing project. By considering the compatibility, corrosion resistance, shank type, and length of the nails, you can make informed decisions that will contribute to a long-lasting and reliable roof. Following installation best practices guarantees a secure and weather-resistant roofing system that will protect your home for years to come.
