Roofing felt, a critical component of roofing systems, plays a pivotal role in protecting your home from moisture and leaks. To securely attach roofing felt, choosing the right type of nails is essential. In this article, we’ll provide straightforward guidance on the nails best suited for roofing felt installation.
The Basics of Roofing Felt
Roofing felt, also known as tar paper or underlayment, is a protective layer installed between the roof deck and the final roofing material, such as shingles or metal roofing. It serves as a moisture barrier, preventing water from infiltrating your roof and causing damage to the underlying structure.
What Type of Nails to Use
When it comes to attaching roofing felt, you should opt for roofing nails that are designed specifically for this purpose. Here are the key considerations:
1. Material
Choose roofing nails made from corrosion-resistant materials, such as galvanized steel or stainless steel. These materials are less prone to rust, which is crucial for ensuring the long-term effectiveness of the underlayment.
2. Shank Type
Roofing nails for felt typically have a smooth shank. The smooth design allows for easier installation and minimizes the risk of tearing the felt. Avoid using nails with barbed or ringed shanks, as they may damage the underlayment.
3. Length
The length of the nails should be adequate to penetrate through the roofing felt and securely into the roof deck. Nails that are around 1 inch to 1.5 inches in length are suitable for most roofing felt applications.
4. Head Style
Roofing nails used for felt generally have a large, flat head. This wide head helps secure the felt in place and prevents it from pulling through the material or lifting during high winds.
Installation Tips
When installing roofing felt, keep the following tips in mind:
-
Spacing: Space the nails evenly along the edges and in the field of the roofing felt. Typically, nails should be spaced around 6 to 8 inches apart.
-
Overlap: When overlapping multiple strips of felt, ensure there is a 2-3 inch overlap between sheets. Nail through the overlapping area to secure both layers.
-
Edge Nailing: Pay particular attention to nailing along the edges, which are more vulnerable to wind and water penetration.
-
Avoid Overdriving: Be cautious not to overdrive the nails, as this can tear the felt. Use the appropriate air pressure or nail gun setting to control the depth.
-
Check Local Codes: Always check local building codes and manufacturer recommendations for specific requirements regarding roofing felt installation in your area.
In Conclusion
Selecting the right nails for roofing felt is a simple yet crucial decision in the construction or repair of your roof. By choosing the appropriate material, shank type, length, and head style, you can ensure a secure and weather-resistant underlayment. Proper installation techniques further guarantee that your roofing felt will effectively protect your home for years to come.
