Roofing felt, commonly used as an underlayment for various roofing materials, plays a crucial role in protecting your roof from moisture and ensuring its longevity. When it comes to securing roofing felt, the choice of nails is equally important. In this article, we will explore the key considerations for selecting the right nails for roofing felt installation.
1. Nail Type:
When securing roofing felt, it’s essential to use nails specifically designed for this purpose. Roofing nails or felt nails are the most suitable choice. These nails have a wide, flat head that holds the felt firmly in place without tearing it.
2. Nail Material:
Roofing nails for felt are typically made of galvanized steel or stainless steel. Galvanized steel nails are cost-effective and offer adequate corrosion resistance. However, if you live in an area with high humidity or near the coast, stainless steel nails are a better choice due to their superior rust resistance.
3. Nail Size:
The appropriate nail size for roofing felt typically falls in the range of 1 inch to 1.5 inches. This size provides enough penetration to secure the felt but not so much that it risks damaging the underlying roof structure. It’s crucial to avoid using excessively long nails, which can lead to over-penetration and potential roof leaks.
4. Shank Type:
Roofing felt nails are available with smooth or ring shanks. Ring shank nails offer better holding power and are less likely to back out over time. They provide added security, especially in areas prone to strong winds.
5. Application Method:
The preferred method for attaching roofing felt is with a hammer, specifically a roofing hammer or a hammer tacker. These tools are designed for roofing applications and make it easier to drive the nails consistently and evenly.
6. Nailing Pattern:
To secure roofing felt effectively, it’s important to follow a consistent nailing pattern. Typically, nails should be spaced 6 to 8 inches apart along the edges and 12 to 16 inches apart in the field of the felt. This pattern ensures even distribution of the fasteners and prevents sagging or wrinkling.
7. Roofing Felt Thickness:
The thickness of the roofing felt can also influence nail size and length. For standard 15-pound felt, 1-inch nails are usually sufficient. However, if you are working with heavier 30-pound felt, opt for 1.25 to 1.5-inch nails to ensure proper attachment.
In Conclusion:
Selecting the right nails for roofing felt installation is vital to ensure the structural integrity and water-resistant properties of your roof. Choose roofing nails with the appropriate size, material, and shank type, and use the correct nailing pattern for a secure and long-lasting roofing felt installation. When in doubt, consult with your roofing material manufacturer or a professional roofer for guidance specific to your project.
