Roofing felt is a crucial component of any roofing system, providing an additional layer of protection against water infiltration. When it comes to fastening roofing felt, the choice between using nails or staples is a common dilemma. In this article, we’ll provide clear and concise information to help you make the right decision.

1. Roofing Felt Overview

Roofing felt, often referred to as tar paper or underlayment, is a lightweight, waterproof material placed beneath the shingles or other roofing materials. Its primary purpose is to act as a moisture barrier, preventing water from seeping through the roof and causing damage to the underlying structure.

2. Nails for Roofing Felt

Nails have long been the traditional choice for fastening roofing felt. Here are some key points to consider:

• Material: Roofing nails are typically made of galvanized steel, which resists corrosion and rust.

• Size: Commonly, 1-inch nails are used, but 1.25-inch nails are also suitable for added security.

• Spacing: Nails should be spaced approximately 9 to 12 inches apart along the horizontal seams and about 6 inches apart along the vertical seams.

3. Staples for Roofing Felt

Staples are an alternative option for securing roofing felt. Here are the essential details:

• Material: Stainless steel staples are preferred as they are resistant to corrosion.

• Size: 1-inch staples are typically used, ensuring proper penetration without damaging the felt or over-penetrating.

• Spacing: Similar to nails, staples should be spaced 6 inches apart along the vertical seams and 9 to 12 inches apart along the horizontal seams.

4. Considerations for Your Choice

When deciding between nails and staples for roofing felt, consider the following factors:

• Local Building Codes: Some regions may have specific building codes that dictate the fastening method for roofing felt. Always check with local authorities to ensure compliance.

• Climate: In areas with high winds, nails are generally recommended due to their superior holding power.

• Personal Preference: Some roofers prefer one method over the other based on their experience and comfort level.

5. Installation Tips

• Use a roofing hammer or a pneumatic nail gun for nails.

• For staples, a staple gun designed for roofing applications is ideal.

• Always follow the manufacturer’s recommendations for the specific roofing felt you are using.

6. Conclusion

Whether you choose nails or staples for fastening roofing felt, the key is to ensure that the material is securely attached to the roof substrate. Both methods have their merits, and your choice should be based on local regulations, environmental conditions, and personal preference. Proper installation is crucial to the longevity and effectiveness of your roofing system, so take the time to do it right.
