Roofing Nails Explained: Uses and Types

Did you know that the average roof installation requires thousands of nails to secure the shingles and other materials in place? That’s right – the number can range from 10,000 to 15,000 nails for a typical roof! Roofing nails play a crucial role in the stability and longevity of your roof, ensuring it can withstand the elements and protect your home.

Key Takeaways:

  • Roofing nails are essential for securing shingles, roofing felt, and other materials in place.
  • There are different types of roofing nails, including smooth shank, ring shank, and square cap nails.
  • The choice of roofing nail material depends on factors such as strength, corrosion resistance, and compatibility with the roofing material.
  • Length and size of roofing nails vary based on the thickness of the roofing material and sheathing.
  • Using the recommended nails for specific roofing materials is crucial for optimal performance.

Types of Roofing Nails

When it comes to roofing nails, there are three basic types: smooth shank, ring shank, and square cap. Each type serves a specific purpose, offering unique advantages for different roofing applications.

  1. Smooth Shank Nails: These nails have a plain, smooth surface and are the most basic and affordable option. They are suitable for general roof installations but may not provide as much grip or holding power as other types.
  2. Ring Shank Nails: With grooves along the shank, ring shank nails provide extra grip and strength. This makes them ideal for areas prone to high winds, as they offer better resistance against pulling forces.
  3. Square Cap Nails: Square cap nails feature a square-shaped head and are specifically designed for fastening felt underlayment. The large surface area of the cap helps secure the underlayment effectively.

Choosing the right type of roofing nail for your project is crucial to ensure proper installation and long-lasting performance.

Roofing Nail Materials

Roofing nails are available in various materials, each with its own unique properties that make them suitable for specific roofing applications. The choice of material depends on factors such as durability, weather resistance, and cost.

Here are some common roofing nail materials:

  • Steel: Steel nails, whether stainless or galvanized, are popular choices due to their strength and corrosion resistance. They can withstand the elements and are suitable for most roofing projects.
  • Copper: Copper nails are often preferred for slate roofs because they are highly resistant to rust and corrosion. These nails add an aesthetic appeal to the roof while providing durability.
  • Galvanized steel: Galvanized steel nails are coated with zinc to enhance their corrosion resistance. This makes them ideal for areas with high humidity or coastal regions.
  • Aluminum: Aluminum nails are lightweight and cost-effective. However, they are not recommended for coastal areas due to their susceptibility to rust.

Roofing Nail Materials

Choosing the right material for your roofing nails is important to ensure the longevity and performance of your roof. Consider the environmental factors and specific requirements of your roofing project when selecting the appropriate material.

Material Strength Corrosion Resistance Suitable Roofing Applications
Steel High High Most roofing projects
Copper Medium High Slate roofs
Galvanized Steel High High Coastal regions, high humidity areas
Aluminum Low Low Non-coastal regions

Length and Size of Roofing Nails

Roofing nails come in various lengths, typically ranging from one to two inches, depending on the thickness of the roofing material and sheathing. The length of the nail should allow the diamond-shaped point to penetrate completely through the wood or decking. The length of the nail is often referred to in penny length, with common sizes including 2d, 3d, 4d, 5d, and 6d. Additionally, roofing nails come in different gauges, with 12-, 11-, and 10-gauge being the most common options.

Recommended Nails for Different Roofing Materials

When it comes to specific roofing materials, it is important to use the recommended nails. Screws should not be used for roofing shingles; instead, roofing nails should be used as approved fasteners. For shingles, ring roofing nails made of hot-dipped galvanized steel with a gauge of 12 or thicker are recommended. Felt/underlayment requires roofing cap nails with large plastic caps for heads. Roof flashing and sheathing can be fastened with standard nails, depending on the building code and local regulations.

Quantity and Cost of Roofing Nails

When it comes to roofing projects, understanding the quantity and cost of roofing nails is essential. The number of nails required per square depends on the exposure and coverage of the shingles. Generally, higher coverage results in fewer nails needed per square. The cost of roofing nails can vary based on factors such as material, type, and length.

Roofing nails are typically sold by the pound, making it important to estimate how many nails you’ll need for your project. Professional roofers often buy nails in bulk to save on costs. Comparing prices from different suppliers can also help you find the best deal.

Roofing Nails

As an example, a small 5-pound box of galvanized steel roofing nails can cost approximately $10 on average. Remember to consider the specific requirements of your roofing project and choose nails that meet the necessary standards and specifications.

Comparison of Roofing Nail Costs

Nail Material Average Cost (per pound)
Galvanized Steel $5 – $15
Stainless Steel $15 – $40
Copper $20 – $70
Aluminum $5 – $15

Note: These prices are approximate and may vary depending on the supplier and location.

Tips for Fixing Nail Pops in a Roof

Nail pops in a roof can be a common occurrence due to various reasons such as underdriven nails or warped decking. It’s important to address these nail pops promptly to prevent further damage to your roof and ensure its longevity.

  1. Remove the nails: To fix a nail pop, carefully remove the nail using a pry bar or hammer. Make sure to remove any loose pieces to create a clean and stable surface.
  2. Replace the shingle: After removing the nail, it’s essential to replace the damaged shingle. Use a new shingle that matches the existing ones in terms of size, color, and material to maintain a cohesive appearance.
  3. Choose the correct nail length: When installing the new shingle, it’s crucial to use the appropriate nail length. Ensure that the nail fully penetrates through the shingle, allowing for a secure and tight fit.
  4. Avoid temporary fixes: Hammering the nail back in, renailing it in the same spot, or reusing the same shingle are temporary fixes that should be avoided. These methods may not provide a long-lasting solution and can leave your roof vulnerable to water penetration.
  5. Seal exposed nails: After installing the new shingle, it’s recommended to seal any exposed nails with a roofing sealant. This will provide an extra layer of protection against water intrusion and help maintain the integrity of your roof.

Remember, reusing roofing nails is generally not recommended for optimal roof performance. It’s best to use new nails to ensure the stability and longevity of your roof.
